System integration testing, ServerPac delivery and installation, an extended service plan, and a broader release-to-release coexistence policy define OS/390 Version 2 as a comprehensive network application server operating system for the entire range of IBM's S/390 customers. Release 6's availability as the third release in Version 2, and the function and value coming in Release 7 sustain S/390's delivery of the OS/390 objectives.



OS/390 Version 2 Release 6 Overview

S/390 Server Consolidation Initiative: The S/390 Server Consolidation Initiative's goal is to help customers consolidate workloads to S/390, help achieve customer-required cost reductions, and exploit new technologies and functions that can enhance enterprise management, security, and application integration. In this way, customers can have the ability and flexibility to compete in their market and grow their business.

With OS/390 Release 6, S/390 continues to deliver the ability customers require to rehost their workload to OS/390, a traditionally strong application environment. The following items are new, enhanced, or run with OS/390 Release 6 for the Server Consolidation Initiative:

  • Application Consolidation through Enhancements in OS/390 UNIX Systems Services (OS/390 UNIX): Multiple performance enhancements in OS/390 UNIX can make it more attractive for customers to consolidate UNIX applications on OS/390. More details are provided in the Applications Initiative section.

  • Tivoli Management Framework: The complexity and, consequently, the costs of managing the entire IT environment of an enterprise can be reduced with the agent functions of the Tivoli Management Framework and applications becoming available on OS/390.

  • Security and Directory: Among several improvements to RACF is an enhancement to Digital Certificate support. Certificates can now automatically be authenticated to RACF. In addition, LDAP client support is elevated to the Version 3 protocol level.

  • RMF's Parallel Sysplex Configuration Support: Several new RMF monitors enable customers to analyze performance bottlenecks or problems in the Coupling Facility. Customers can see the immediate state of the Coupling Facility and the results of a tuning action. New overview report results can be directly integrated into the spreadsheet report facility for easy presentation and evaluation.

  • As part of the Novell Network Services for OS/390 Release 1, Novell Directory Services (NDS) will provide directory support for new and existing Novell customers and will be available in the Release 6 time-frame. It will run on S/390 and enable clients to login, administrators to manage their networks, and customers to reduce and consolidate their PC-based directory servers.
S/390 e-business Initiative: The S/390 e-business Initiative's goal is to continue the rapid evolution of S/390 as the platform of choice for highly available, scalable, and secure e-business. S/390 is a key player in the Internet/intranet opportunity and will remain so as new leading-edge capabilities are added to OS/390. IBM expects to continue to deliver functional extensions to the Java (TM) Development Kit (JDK), enhancements to the eNetwork Communications Server and Security Server, further support Firewall technologies, provide a value-added framework by delivering companion products for Domino for S/390, and a host of other e-business deliverables. IBM will also provide an easy to use OS/390 Automated UNIX System Option that will support S/390 e-business applications. For a summary of recent announcements and deliverables, refer to the following Web site URL: The following items are new or enhanced in OS/390 Release 6 in support of the e-business Initiative:

  • eNetwork Communications Server enables optimal IP communications over high-speed links and helps improve throughput and reduce overhead for large FTP files. In addition, it provides:
    • UNIX standard sendmail
    • Open Shortest Path First (OSPF) routing
    • Secure Sockets Layer (SSL) security for TN3270 users
    • Virtual Private Network (VPN) enhancements
    • Significant performance improvements over MVS TCP/IP V3R2
  • OS/390 Network File System (OS/390 NFS), formerly delivered as DFSMS/MVS (R) NFS, is enhanced to continue the improvement of OS/390 as an effective participant in a distributed enterprise. OS/390 NFS provides a UNIX file system with the OS/390 capacity, storage management, and reliability. Enhancements help address important customer productivity, usability, and performance requirements.

    In addition to supporting the SUN NFS Version 2 protocols, the OS/390 NFS client and server is enhanced to support the SUN NFS Version 3 protocol specification. Both versions coexist in this OS/390 NFS release. OS/390 NFS now supports TCP (Transmission Control Protocol) as a transport, in addition to UDP (User Datagram Protocol) for the server for both NFS Version 2 and Version 3 protocols. OS/390 NFS is enhanced with the WebNFS protocol, an extension of the SUN NFS Version 2 and Version 3 protocols. This enhancement enables a customer's Java applications to exploit the NFS file sharing capabilities.

S/390 Applications Initiative: The S/390 Applications Initiative's goal is to deliver new applications, new infrastructure in support of programming environments, and new support for application growth through tools for S/390 and OS/390. The Applications Initiative's customer-driven focus is based on Object-Oriented Component Broker technology, OS/390 UNIX technology, and technologies that can optimize application development, porting and execution while delivering a low-cost hardware and software platform solution.

Component Broker for OS/390 will provide an environment for hosting new business applications on S/390 that can help enable customers to rapidly design and develop their applications. The Component Broker's new programming model is the same across multiple platforms. Upon completion of its concept validation program, Component Broker for OS/390 may be ordered through a Beta program by customers with OS/390 Version 2 Release 5 or later releases.

The following items and enhancements are delivered in OS/390 Release 6 in support of the Applications Initiative:

Language Environment support includes performance improvements (new runtime option and reduced path lengths for multiple functions) and RAS enhancements (better data capture during formatting of CEEDUMP).

OS/390 UNIX contains key enhancements in support of customer requests for improved performance. Current CMOS machines offer the capability for applications to take advantage of Binary Semaphores using Perform Locked Operations (PLO). Shared Memory improvements can dramatically reduce the real storage usage. NFS customers can achieve path length savings with the new optimization of the Logical File System (LFS).

An easy-to-use OS/390 Automated UNIX System Option will be available as an additional OS/390 delivery vehicle during the OS/390 Release 6 time-frame for an additional charge. This new delivery option is intended to provide a UNIX application platform that is easily installed and designed to not require any OS/390 system programming skills for management or maintenance. It can help provide a low total-cost-of-computing solution for small remote or departmental solutions in large enterprises.

S/390 Technology Leadership Initiative: S/390 provides an infrastructure of hardware, software, and Parallel Sysplex technology that responds quickly and easily to dynamic customer requirements and new opportunities. S/390's enhanced leading-edge technology integrates software and hardware functions to offer comprehensive end-to-end (from small to very large) enterprise solutions required in today's extremely fast-paced and competitive business environments. These capabilities are the defining standard in enterprise computing, and are the focus of the S/390 Technology Leadership Initiative.

The following items and enhancements are delivered in OS/390 Release 6 in support of the Technology Leadership Initiative:

IBM continues to enhance Parallel Sysplex, the S/390 industry-leading clustering technology. New functions in Release 6 provide reduced complexity for certain coupling facility management situations and enhanced Coupling Facility availability.

Release 6 support for the common industry standard IEEE Floating Point hardware in the IBM S/390 Generation 5 Server enhances OS/390 openness. This support provides improved performance for Java applications using floating point operations (with a new release of JDK available year-end 1998) and for C/C++ applications (when recompiled). Portability is improved for C/C++ applications and Domino Companion Products that use floating point.

To address a scalability concern, BCP Base enhancements remove the BCP architectural limit of 10,000 concurrent dynamically allocated DB2 (R) data sets. In combination with a DB2 V5 APAR change, customers can use more than 10,000 dynamically allocated data sets to define their DB2 data bases.

The S/390 Open Systems Adapter 2 (OSA-2) feature is enhanced to support 100 Mbps Ethernet (Fast Ethernet). This new support satisfies network performance problems by providing direct access from S/390 or S/390-compatible servers to high-bandwidth and high-capacity campus LAN backbones.



OS/390 Version 2 Release 7 Overview

The following information is an early look at a subset of significant items that will be new or enhanced in Release 7. The complete list of Release 7 items and enhancements will be announced prior to the March 1999 general availability of Release 7.

S/390 Server Consolidation Initiative: IBM will provide the next step toward enabling OS/390 to be a key platform in a Tivoli management environment by integrating the Tivoli Management Agent into OS/390 Release 7. Major OS/390 Systems Management Products, such as Security Server and HCM will provide support for their Tivoli counterparts. Customers will now be able to use Tivoli management software to integrate management of OS/390 with management of other servers and to leverage the strengths of traditional Systems Management products on OS/390 at the same time. This will be a significant step toward enabling OS/390 to be the management server for the entire enterprise. Concurrent with this new support, the SystemView (R) for MVS Base Version 1.1-level element that has been integrated into earlier OS/390 releases will no longer be available starting with Release 7.

S/390 e-business Initiative: IBM plans to deliver functional extensions to the WebSphere Application Server that will be integrated into OS/390 Version 2 Release 7. Performance enhancements will provide up to a two times performance improvement for basic Web page serving.

eNetwork Communications Server's Firewall Technologies are being enhanced with upgraded IPSec function, performance and RAS improvements, and support for Triple DES encryption in a Virtual Private Network (VPN).

eNetwork Communications Server for OS/390 (CS OS/390) Version 2 Release 7 -- An Enterprise Class Solution for e-business Networking: CS OS/390 will provide enhanced usability, availability, and performance for TCP/IP in a Parallel Sysplex environment through the use of Sysplex Sockets, XCF Dynamics, and System Symbolics. CS OS/390 will provide Fast Response Cache Accelerator which will extend S/390's lead as the e-business server of choice. CS OS/390's service policy agent will provide prioritized networking for TCP/IP enabling control according to:

  • Service Level Agreements
  • Classes of users
  • Application needs (for example, high bandwidth)
  • Mission-critical applications
  • Time of day
CS OS/390 Internet security will be further improved with Triple DES, latest RFCs, SNMPv3, and more.

S/390 Applications Initiative

OS/390 UNIX System Services will have numerous enhancements. Performance and RAS capabilities will offer faster, more efficient performance. The WebSphere Application Server will run CGI programs faster. Installation improvements will eliminate post installation jobs, improve file system support, and simplify installation setup. Support of automatic installation of SSL certificates will remove the need for the system administrator to perform this setup.

S/390 Business Intelligence Initiative: The goal of the S/390 Business Intelligence (BI) Initiative will continue the evolution of S/390 Parallel Sysplex technology-capable hardware and OS/390 to meet the needs of increasingly diverse BI applications running on the S/390 platform. IBM is investing significant resources in DB2 and Data Mining technologies, S/390 Parallel Sysplex technology, OS/390 with Workload Manager, and DB2 for OS/390 to support parallel queries and mixed query workloads in a data sharing environment. Existing OLTP and query applications and new query and ported applications from UNIX and Windows NT (R) environments will run on a cost-effective, secure, robust, large-scale S/390 Enterprise Server with OS/390 systems management.

The OS/390 UNIX System Services Parallel Environment will be enhanced in Release 7 to support the MPI 1.2 specification for C and C++ applications. Further enhancements include POSIX file support for essential parallel I/O interfaces, support for multi-threaded user applications, support for the Multiple Program Multiple Data (MPMD) parallel application model, and various usability improvements.

S/390 Technology Leadership Initiative

DFSMS/MVS Version 1 Release 5 will deliver a major restructuring of HFS to improve performance. Reduced path lengths, removal of serialization bottlenecks, and improved buffering capabilities will enable an order of magnitude improvement in throughput for files less than 512 KB in size. More detailed performance information will be available at Release 7 general availability.

Customers will be able to operate DFSMS/MVS Version 1 Release 5 in a Parallel Sysplex environment, to enable multiple DFSMShsm (TM) sub-plexes, to perform secondary host promotion if the DFSMShsm operation on the primary host fails, and to access OAM objects from any system in the Parallel Sysplex environment. DFSMSrmm (TM) usability enhancements will provide an API for read/write access, support of separate retention and vaulting policies, and enablement of special handling instructions. New DFSMSdfp (TM) usability enhancements will provide the majority of required functions customers require for Naviquest batch, support for master catalog alias resolution by system, and shared catalog access in a Parallel Sysplex environment. Customers will have the growth capability they require because of the planned support for multi-volume HFS, enablement of a large number of open datasets for IMS (TM) and CICS (R) Subsystems, and removal of the DFSMShsm CDS limits. Enablement of extended addressability (EA), partial release, and candidate volume space amount will be available for extended format VSAM data sets, other than KSDS.

DFSMS/MVS Version 1 Release 5, which is available as a separate product (5695-DF1), will run with OS/390 Version 2 Releases 5, 6, and 7. DFSMS/MVS Version 1 Release 5 will run with MVS/ESA SP (TM) 5.1, 5.2, and 5.2.2 without OpenEdition (R) MVS (now renamed OS/390 UNIX in OS/390). DFSMS/MVS Version 1 Release 5 will only support OS/390 UNIX on the OS/390 platform.

SUPPLEMENTAL INFORMATION



OS/390 VERSION 2 RELEASE 6 FUNCTION DESCRIPTION



S/390 (R) Server Consolidation Initiative

For some businesses, the proliferation of servers in networked environments has led to high management costs and server management nightmares. Many IT managers are rethinking their IT infrastructures and are considering centralizing or consolidating distributed servers. They are identifying a need to simplify, secure, and reduce operational costs.

The S/390 Server Consolidation Initiative focuses on helping customers reduce costs and complexity and improve overall network security. With OS/390 (TM), the S/390 flagship enterprise operating system and enabling technology for effective server consolidation, customers can:

  • Consolidate servers through rehosting application and data workloads

  • Improve systems management and security through centralized administration, operations, availability, and security management

  • Integrate core applications with new applications through OS/390 distributed transaction processing
Each of these areas helps leverage the scalability, reliability, security, and availability of S/390 and can reduce total cost of ownership, increase systems management efficiency, and enhance data integrity. With OS/390 Version 2 Release 6, the Server Consolidation Initiative focuses on systems management and application and data consolidation.

Enterprise Systems Management and Security: Continuing consultant studies show that the strong Systems Management and Security capabilities of the platform are one of the reasons why customers chose to consolidate on S/390. These studies confirm that customers are saying that managing the distributed environment is one of the biggest challenges in 1998. S/390 can address both of these aspects. S/390 has a 25-year history in providing superior Systems Management solutions through products offered by the S/390 Division, products offered by SSD (Storage Management) and, more recently, through Tivoli (Network and Systems Management) solutions. Complementary vendor products have also filled niches or offered alternatives to IBM offerings and validate both the strength and manageability of the S/390 platform. With this release, significant enhancements have been added to IBM products primarily in the area of Parallel Sysplex (R) management. Managing the distributed environment is addressed by Tivoli's solutions today. S/390 development is actively engaged with Tivoli to enable Tivoli management software on OS/390 to manage the complete enterprise including OS/390, UNIX (R), Windows NT (R), and other systems.

Application and Data Consolidation: S/390 delivers the ability to rehost workloads to the S/390 platform to help customers shrink complexity and operating costs by reducing the number of servers, administration and support staff, and the duplication of applications and data. OS/390 UNIX System Services (OS/390 UNIX) formerly delivered as OpenEdition (R), and the Bristol Wind/U product provide customers, respectively, with the flexibility to run UNIX applications and a set of Windows NT applications on S/390. More details about improvements of the OS/390 UNIX Systems Services can be found in the Applications Initiative section.



S/390 Server Consolidation Initiative Release 6 Items

  • Enterprise and Systems Management
    • RMF (TM) continues to provide customers improved support of the Parallel Sysplex environment and new hardware with the following enhancements:

      Online Reporting for the Coupling Facility: Three new Monitor III reports enable customers to analyze bottlenecks or problems in the coupling facility area that might result in a performance degradation in a Parallel Sysplex environment. To avoid critical situations for production databases and transaction processing systems, customers can see the immediate state of the coupling facility and structures and they have all relevant data at a glance in a granularity they can choose. In addition, they can immediately see the results of tuning actions in this area (for example, after having removed a coupling structure from an overloaded coupling facility to another one). This new RMF function addresses many requests of customers who already exploit Parallel Sysplex technology.

      Parallel Sysplex Technology Overview and Spreadsheet Reporting: Overview data is available for the three Postprocessor Parallel Sysplex reports (workload activity in goal mode, coupling facility activity, and shared device activity), based on the same technology as currently used for overview and exception data for single reports. This is a major step toward an integrated Spreadsheet Reporter solution not restricted to spreadsheet data from Postprocessor single-system reports. Customers can choose from a variety of overview criteria to tailor the appearance of an Overview report or the contents of overview records. Especially when using Parallel Sysplex overview criteria, the Postprocessor provides a Parallel Sysplex and a single-system view to shared resources, for example, service classes, devices or coupling facility structures. In addition, a new Collector function is included in the Spreadsheet Reporter application to start Postprocessor jobs from the workstation without requiring an explicit host logon. This is a significant usability enhancement.

      Enhancements for the I/O Subsystem Support: The enhanced Postprocessor Cache Subsystem Activity report provides the control unit hardware type and model as additional information. With the availability of storage subsystems that can be defined with more than 128 devices, RMF supports this new capability in all relevant reports. The new IOS CHPID Description Service gives the acronym of an installed channel path type. RMF's support of this new function results in a smoother integration of new channel types and primarily avoids SPEs for their support. This is another usage of using the same technology to integrate all OS/390 elements and features.

    • HCM with TCP/IP as additional communication protocol: Besides using APPC as one communication protocol to exchange data between HCD and HCM, customers are able to use TCP/IP as another protocol. This support is also available via SPE PTFs for OS/390 Version 2 Release 4 HCM. This eliminates the restriction of using APPC as the only protocol for communication between HCD and HCM.

    • As part of the Novell Network Services for OS/390 Release 1, Novell Directory Services (NDS) will provide directory support for new and existing Novell customers and will be available in the Release 6 time-frame. Novell Network Services for OS/390 will run on S/390 - a server known for its outstanding reliability, backup, and data integrity strengths -- and enable clients to login, administrators to manage their networks, and customers to reduce and consolidate their PC-based directory servers.
  • Security and Directory

    The following security enhancements are part of the Server Consolidation Initiative. For an overview of all security-related enhancements for OS/390 Release 6, refer to the Additional Information on OS/390 Release 6 section of this announcement.

    RACF (R) Digital Certificate Enhancement: Users can currently access information on an OS/390 server via the Internet using the WebSphere Application Server for OS/390 (formerly known as Domino (TM) Go Webserver). Security is created between the client workstation and WebSphere Application Server for OS/390 using digital certificates for authentication. In OS/390 Version 2 Release 4, security services for Web-computing were integrated with the OS/390 Security Server by enabling RACF to accept digital certificates authenticated by WebSphere Application Server for OS/390 without requiring a RACF userid and password for each client when Web pages were accessed. This change eliminated the need for the client to authenticate multiple times.

    In OS/390 Release 6, RACF Digital Certificate is enhanced to enable certificates to be automatically authenticated to RACF. It is no longer necessary for an administrator to manually transmit (using the RACDCERT command on TSO) the client certificate to OS/390. A registration page is used to prompt for registration of the user's certificate and RACF userid. When the user clicks on the registration box, a secure session is set up. The certificate is automatically installed when first presented by the client.

    As many industries now conduct business transactions over the Internet, a key challenge has been to leverage existing Information Systems (IS) systems and data in order to conduct business safely. IBM is stepping up to this challenge on OS/390 by simplifying access to business-critical information by others and providing effective and manageable control over access to IS resources. The digital certificate enhancements in OS/390 Release 6 are another step in IBM's continuing plans to provide a complete robust public key infrastructure and integrate Web applications with seamless control over access to critical information. This support is available back to OS/390 Version 2 Release 4 and Release 5 via PTF.

    RACF Administrative Enhancements: RACF userid administration is made more efficient in OS/390 Release 6 by providing the ability to reset passwords, resume userids and list users without requiring the RACF SPECIAL or group-SPECIAL attribute. Security administrators can control who is allowed to perform these functions through profiles in the FACILITY class. This support enables greater granularity of control for customer installations. Especially useful in a help desk environment where only partial authority is required, this support does not override current authorization mechanisms and is available back to OS/390 Version 1 Release 3 and Version 2 Release 4 and Release 5 via PTF.

    In addition, administrators can now reset a user's password without requiring that the user change it upon first use. A new option (NOEXPIRED) on the ALTUSER command enables customers to specify a new password value that does not have to be changed upon first use. This support is also available back to OS/390 Version 1 Release 3, and Version 2 Release 4 and Release 5 via PTF.

    Removing class authority has also been made easier in OS/390 Release 6. Specify NOCLAUTH on the RACF ALU command for a class that does not exist in the Class Descriptor Table (CDT).

    Transportable Access Control Environment Elements (ACEEs): With Release 6 of the OS/390 Security Server, support for the RACF Environment Object is extended to simplify retrieval, construction, and transportation of security environments across address spaces or on another system in a Parallel Sysplex environment. This support is provided through enhancements to the RACROUTE REQUEST=EXTRACT macro and the INITACEE callable service. Component Broker technology, available with OS/390, exploits this function.

    RACF Support For Network Qualified LU Names: With the Release 6 OS/390 Security Server, the restriction that network LU names be unique across interconnected networks is removed. Also included is the ability to specify an additional qualifier in APPC information that is passed to RACF to identify the remote network in existing APPCLU and APPCPORT classes. Customers, with interconnected networks containing the same LU names, can now differentiate them. Included for a 17-byte network qualified name, this support increases the flexibility of communication and the use of resources among networks.

    RACF Support For OS/390 UNIX: With OS/390 Release 6, it is now possible for an existing OS/390 UNIX process to create a new security identity without creating a new address space. RACF now supports this capability of having multiple processes and multiple users in a single address space. This support enables customers to more easily port applications to OS/390 that may already be in use on other platforms. This increases the usability of those applications in addition to making a more scalable environment available.

    Additionally, auditors can determine when a user is a superuser and determine the user's identity. A new function code (via SMF type80) enables a full audit trail that can be used to ensure adequate security.

    RACF Interface Enhancements (Support for Tivoli Products): The OS/390 Security Server for Release 6 has been enhanced to provide the programming interfaces which enable RACF to be managed by other applications. All RACF user segments are supported by Tivoli User Administration for OS/390 (which works with Tivoli User Administration) to manage users throughout the enterprise. In addition, RACF groups and resources are supported by Tivoli Security Management for OS/390 (which works with Tivoli Security Management) to manage groups and resources throughout the enterprise. These two Tivoli applications will support OS/390 (RACF) via the Tivoli Management Agent during the fourth quarter 1998.

    The RACF R-admin callable service is updated to support adding, altering, deleting, and listing data set and general resource profiles. Also, a new function code enables a user or group to be permitted access to a data set or general resource.

    This support improves the usability of RACF resource access management. In addition, the capability to integrate management of RACF and the security of other platforms, as provided by the Tivoli Management software, can result in security administration cost savings. An administrator is required to be proficient with only one set of user dialogs and administration methodologies. For more information about the Tivoli products, refer to the Tivoli Web site at URL:

    LDAP V3 Client Support: The LDAP client support is elevated to the Version 3 protocol level. With this new support, Version 3 LDAP clients on OS/390 can exploit the latest Version 3 LDAP server function on other platforms, including better referral processing and improved international character support.

    LDAP Multi-Server Support Introduction: LDAP server support enables multiple instances of the LDAP server to be operational in the same OS/390 system. This is useful where different sub-trees of a directory namespace need to be managed by different servers or groups, or when a single namespace needs to be accessed by many different users at the same time. If multiple LDAP servers are defined, as in the latter situation (high usage rate), this improves availability: if one server goes down, another remains available to handle requests.

  • Workload Consolidation
    • OS/390 Print Server, introduced as a new optional priced feature of OS/390 in Version 2 Release 5, enables printers to be defined in a central repository so that any user in the enterprise can send print jobs to any printer. LAN users and applications that run in the OS/390 UNIX environment now have access to the same print capabilities as applications that run under traditional MVS (TM), including high-speed AFP (TM) printers and TCP/IP-attached LAN printers.

      New NLS support in Release 6, not delivered in Release 5, extends the benefits of OS/390 Print Server to Japanese and Spanish language environments.

    • OS/390 Distributed File Service (DFS) continues to maintain functional equivalence and compatibility with OS/390 DCE and DCE DFS implementations on other system platforms. The DFS support includes:

      OSF 1.2.2 level support for 64-bit file systems: OS/390 DFS clients can handle 32-bit or 64-bit DFS file servers. It also enables an OS/390 DFS file server to export HFS data sets with files that have a size greater than 32-bits.

      Performance and RAS enhancements based on customer experiences: While still controlling the DFS server as if it were running in a single address space, new support allows the DFSKERN server process to be run in a separate address space. This enables address space termination processing to free all file and other resources held by DFS server which enhances the ability for DFS to automatically restart itself after a server failure. Enhancements, that enable memory tracing to be continuously active, improve first-time failure data capture and problem determination. New messages identify the DFS service level and creation date when the DFS server is initialized. DFS backup of multiple file sets to a single tape data set eliminates tape data set open/close overhead. DFS server file exporter performance is improved by using a virtual memory caching system scheme.

      Customer request: To satisfy customer request REQ00064367, the DFS supports translation specifications on a file type (or extension) basis. The OS/390 DFS client can access file sets that include both binary and text files.

    • DCE usability is enhanced by enabling users to configure DCE from batch or OS/390 UNIX, thereby making it possible to automate DCE configuration tasks. This item satisfies customer request REQ00060966.

      DCE now uses the OS/390 Workload Manager in a Parallel Sysplex environment to bind DCE client requests to the best host. This offers basic workload balancing to vendor- and customer-written DCE applications.

  • Business Process Automation

    Transaction Processing: In OS/390 Release 6, the Recoverable Resource Management Services (RRMS) have been extended to recognize Resource Managers that manage work contexts as Work Managers. These services have also been extended to support Problem Program Work Managers. A problem program application can become a Work Manager and manage privately managed contexts within their own address space.

    RRMS system management facilities have been significantly enhanced. These enhancements include support for Work Manager names, wild card filtering capabilities, sorted displays, and exit duration reports. These changes make it much easier to locate and manage RRMS coordinated transactions.

    IMS (TM) Version 6, a stand-alone product that runs with OS/390, is enhanced with some key items for OS/390 Transaction Processing. The IMS Open Database Access (ODBA) facility provides a callable interface for improved access. It uses the IMS Database Resource Adapter (DRA) facilities to enable a connection from any OS/390 Recoverable Resource Management Services (RRMS) managed application-enabled environment to access IMS DB databases. These OS/390 applications that access IMS DB, could include DB2 (R) Stored Procedures, WebSphere Application Server for OS/390 applications, APPC/MVS Transaction programs and/or batch programs. This function is planned for delivery through the service process by December 1998.



S/390 E-BUSINESS INITIATIVE

The S/390 e-business Initiative's goal is to continue the rapid evolution of S/390 as the platform of choice for highly available, scalable, and secure e-business. S/390 is a key player in the Internet/intranet opportunity and will remain so as new leading-edge capabilities are added to OS/390. IBM will continue to ship functional extensions to the Java (TM) Development Kit (JDK), enhancements to the eNetwork (TM) Communications Server and Security Server, provide a value-added framework by delivering companion products for Domino for S/390, and a host of other e-business deliverables. IBM will also provide an easy to use OS/390 Automated UNIX System Option that will support S/390 e-business applications. For a summary of recent announcements and deliverables, refer to the following URL:



S/390 e-business Initiative Release 6 Items

  • The WebSphere Application Server for OS/390, previously delivered as the Lotus (R) Domino Go Webserver 5.0 for OS/390, is now integrated into OS/390 Version 2 Release 6
    • WLM Exploitation Enhancements: Secure Sockets Layer (SSL) requests can now participate in WLM application environment queuing. This provides improved workload management for secure Web requests. This extends the WLM advantages first provided in the Internet Connection Secure Server (ICSS) V2.2 for OS/390 to key business-critical applications.

      Systems resources, such as CICS (R) EXCI connections and DB2 Database, are used more efficiently by controlling into which WLM application environments specific plug-ins are loaded.

    • Java Servlet Support: Java Servlet internal process support is enabled under OS/390 based on the latest available JDK driver. This replaces external process support from a prior release of the Webserver. Existing APIs are maintained. Running an enhanced Java servlet engine, Servlet Express, inside the Webserver address space results in less data transfer for servlet execution and is a significant performance enhancement.

    • Security
      • Key management of server certificates -- Security is improved by running the key management function outside the server but in the same physical machine. This eliminates connecting to the key management function over the network. The complexity of setting up a secure server has been reduced by requiring less interaction from the administrator.

      • Multiple IP SSL -- SSL support for multiple IP addresses is hosted by the same server and provides support for individual certificates associated with each distinct IP address. A single server will sometimes support multiple URLs and IP addresses. This support extends the SSL security protocols from a single, server-wide certificate to allow certificates that are IP-specific.

      • LDAP Support -- Provides centralized access and administration of authentication information (for example, username/password) stored in an LDAP directory. An administrator can now add a user account once and any LDAP-enabled application, such as the Webserver, automatically recognizes the new user. Also, multiple Webservers can share the same configuration file via a new LDAP directive.

      • PKI enablement -- Enables the server to exploit Public Key architecture. Customers can now take advantage of Certificate authorities that issue and revoke client and server certificates. A certificate Revocation List (CRL) is used to notify servers of a certificate revocation. Lightweight Directory Access Protocol (LDAP) is used to retrieve the CRL from the directory server. The Public Key architecture is based on X.500 and X.509 standards.

      • Crypto Keysize -- Enables the server administrator to specify the level of encryption to be used, versus the default, which is the highest (strongest) level common to both the requester and server. The administrator may use a lower level of encryption, when appropriate, with an accompanying improvement in performance, or refuse connection to a requester at levels lower than those the requester specified.

      • 128-bit encryption support for export (outside North America) browsers -- This enables export browsers with 128-bit encryption capability to use 128-bit encryption when communicating with financial institution servers authorized to use 128-bit encryption. This requires a special financial institution server certificate from an authorized certificate authority.
    • Integration of Web Traffic Express (WTE) -- Webserver Proxy Enhancements
      • Proxy caching -- Caching algorithms, specifically aimed at increasing the likelihood of finding a Web object in the local cache, are incorporated into the Webserver. In the past, typical Web object caching algorithms have been derived from traditional computer caching schema where the objects to be cached are of known and consistent sizes. Web objects are variable in size and have different arrival characteristics which were not considered by traditional caching algorithms.

      • Auto cache refresh -- The server has the flexibility of having the automatic cache controlled by the administrator or controlled by algorithms in the server. For example, the administrator might decide to always cache and refresh the company home page on a specific time schedule. Or, the server can be configured to determine the top n (set by the administrator) most frequently accessed pages, cache them, and refresh on a nightly basis. This method could be used to provide fresh high-usage pages at the beginning of the workday or shift.

      • PICS Filtering -- PICS-based filtering in a proxy server enables an administrator to specify which sites will be acceptable and which will not be acceptable for attaching to browser requests. A server administrator can use content-rating information delivered using PICS to make decisions about which sites are viewable or not.

      • Flexible socksification -- A flexible SOCKS implementation supports using a SOCKS server on one host, a nameserver on another host, and intelligently choosing whether to go through the SOCKS server for external sites or directly connecting for internal sites.

      • Activity Monitor -- The Proxy Activity Monitor consists of multiple pages that contain information about the activity of the proxy server, such as cache refresh and garbage collection status.

      • Over-ride of Page Caching Information -- Some Web pages have header information that specifies they be fetched from the source each time they are requested. This might be done, as an example, to maximize the earnings from advertising contained in these pages. This practice tends to use additional network bandwidth resources and extends the time spent waiting for it by the user versus having the page cached. The administrator is provided, by URL, the capability to override the header instructions to not cache. In addition to caching the page, the time interval before refresh can be set.
    • Systems Management Enhancements
      • User-Defined Install Path -- allows multiple copies of a Webserver on the same OS/390 image and provides users with an orderly migration path (co-incident test and production systems).

      • Configuration Enhancements -- the user interface for the Webserver will be frames-based, an industry standard.

      • Multi-line console support -- The Webserver now issues one multi-line message rather than a series of single-line messages to better support the high volume message traffic of S/390 systems.
    • REXX GWAPI (usability item) -- Go Webserver Application Programming Interface (GWAPI) enables users to extend the Webserver's base functions with their own customized process routines. This interface is enhanced to enable these user plug-in routines to also be written in REXX.

    • HTTP 1.1 Compliance -- The Webserver development team is an active participant in the HTTP standards process and is proactively implementing these standards in the Webserver as they are finalized.
    For more information about Domino Go Webserver 5.0 for OS/390, refer to Software Announcement 298-151 dated May 5, 1998.

  • eNetwork Communications Server for OS/390 (CS OS/390) Version 2 Release 6 -- An Enterprise Class Solution for e-business Networking

    In Version 2 Release 6, IBM continues to deliver on its commitment to provide world-class TCP/IP solutions for e-business networks while increasing the integration of SNA/APPN (R) and TCP/IP networking services. Details for the key items and additional enhancements follow.

    Further Dramatic Improvements in TCP/IP Performance: Extending its lead in providing enterprise-class TCP/IP performance for S/390, CS OS/390 Release 6 builds on the dramatic TCP/IP performance improvements introduced with Release 5 to achieve even higher levels of performance. IBM internal tests on a 3-way IBM S/390 G4 S/390 comparing the TCP/IP Services in Release 6 with MVS TCP/IP Version 3 Release 2 using simulated workloads designed to test IP stack performance behavior, showed that Release 6 provides a relative performance of up to*:

    • 7.7 times for Web serving workload
    • 5.7 times for interactive workload
    • 2.7 times for file transfer
    The same tests on a 10-way S/390 G4 resulted in up to*:
    • 16.2 times for Web serving workload
    • 15.3 times for interactive workload
    • 6.4 times for file transfer
    Open Shortest Path First (OSPF): A link-state routing protocol supports customers by providing IP networks improved routing efficiency, flexibility and security. When IP network topology changes, OSPF quickly recalculates routes and generates less route control protocol traffic than Routing Information Protocol (RIP). All OSPF routing protocol exchanges are authenticated to ensure that routing information is not sent to unauthorized systems or users. With these new changes it is possible to discover and react to network failures more quickly than previously possible

    IP Multicast Support: The OSA2 features, in combination with CS OS/390, implement IP Multicast support as defined in RFC 1112 as well as RFC 2236. Therefore, Internet Group Management Protocol (IGMP) Version 1 and Version 2 are supported. Internet Protocol (IP) Multicast provides a more efficient means of transmitting the same data or message to multiple users. With IP Multicast, a set of recipients can be selected and only one copy of data is sent for the group. Using the previous alternatives, unicast resulted in a separate, duplicate message sent to each selected recipient, or broadcast sends a single copy of the data to all hosts on a subnetwork even if they have not requested the data. Thus, IP Multicast saves network resources and users' time.

    IP Multicast can greatly improve scalability since an increase in the number of recipients does not require a corresponding increase in communications bandwidth and IP Multicast servers do not have to support multiple sequential or concurrent sessions. Clearly, IP Multicast is a good solution for sending the same messages or data to groups of users connected to IP networks.

    Applications that may benefit from IP Multicast include:

    • Multimedia
    • Live audio and video feed
    • File transfer
    • Stock quotes
    • OSPF
    • RIPv2 (eliminates broadcast storms)
    CS OS/390 support provides application programming interface (API) extensions that are compatible with the defacto standard Berkeley Sockets IP Multicast API. This should help ease the porting of existing applications.

    SSL Enabled TN3270 Server: CS OS/390 provides for secure communications between the TN3270 server and an SSL-enabled client, such as Host On-Demand Version 2. The SSL protocol provides connection security that includes encryption, initial handshake to specify a secret key, and message transport that includes a message integrity check. Also, with this release, TN3270 server configuration is more flexible by allowing up to 255 Telnet ports to be configured. This multiple port capability is used to establish separate ports for SSL and non-SSL use based on installation security policy.

    High Performance Data Transfer (HPDT) Support for OS/390 UNIX Applications and FTP Exploitation of HPDT Services: One of the major performance costs in the transfer of large data objects is the movement of data. The HPDT support, introduced in OS/390 Version 1 Release 3 for SNA applications, is extended to support authorized OS/390 UNIX System Services written to the assembler application programming interface. This provides improved throughput and CPU utilization for applications that move large amounts of data. In OS/390 Version 2 Release 6, FTP exploits HPDT services for outbound data moves and provides improved throughput and CPU utilization for large data moves.

    Long Fat Pipes: Networks with either a large bandwidth or long distance sensitivity are called Long Fat Pipes and require a larger window size for maximum throughput. CS OS/390 implements the window scale option, defined in RFC 1323. It avoids the limitation of a 16-bit window size field in the TCP header. This enhancement can improve the efficiency of data transmission because it more efficiently fills the capacity of the transmission line. When used in conjunction with High Performance Data Transfer (HPDT) Services even more efficiency can be gained through the reduction of data moves.

    Sendmail (including POP3): Sendmail is the current leading mail server found on UNIX systems. While Domino provides rich collaborative workflow processing, Sendmail (based on industry standard Berkeley 8.7.7 code) offers basic mail transport services in the following types of situations:

    • For users who directly connect to the OS/390 system either through TSO (using OMVS), or remotely with rlogin or telnet

    • For distributed users who use Sendmail POP3 server facility on OS/390 as a store-and-forward vehicle with widely distributed client applications such as, Elm or Pine

    • For system services based on standard mail (SMTP) protocol (for example, call mail reflector)
    Customer cost savings can be achieved through consolidation of mail administration and mail server functions onto OS/390. Sendmail provides the support needed to conduct business over the Internet based upon the SMTP protocol, which includes IBM's commitment to service OS/390, security based on OS/390 Security Services, and space management with OS/390 DFSMS (TM) services. The sendmail function is fully compatible with all SMTP clients, including those provided by Web browsers (Internet Explorer and Navigator) and client systems. Sendmail and the existing MVS mail server (SMTPPROC) coexist in the same system and are able to be connected together as mail gateways.

    MultiNode Persistent Sessions (MNPS) Dependent LU Server Support: This function extends the MNPS Support that was delivered in OS/390 Version 2 Release 5. It enables customers to include recovery of sessions between MNPS applications and dependent LU Requester (DLUR)-owned dependent LUs. With this enhancement, the DLUR now has access to the HPR network. This enhanced MNPS support, when combined with the Enterprise Extender enhancement, can provide the native IP network with nondisruptive session switching for improved availability. By enabling HPR connections over the native IP transport, HPR benefits can be realized while reducing or eliminating the need for DLSw and at the same time it can provide for full Parallel Sysplex technology exploitation.

    Client/Server Affinity: This function provides improved reliability for socket servers that implement synchpoint (multi-phase commit) in a Parallel Sysplex environment. A client/server affinity is created when a client and server exchange transaction state using synchpoint. This new function enables a socket server, which is registered to DNS/WLM, to return a fully-qualified unambiguous name to the client. With this support, a client and server can reconnect and exchange synchpoint states for previous transactions.

    APPN Dynamic Network Node Server Switching: Enhanced Systems management for Network Node server selection provides the ability to dynamically change the preferred Network Node Server specified for a VTAM (R) End Node. A new operator message has been added to provide improved information when displaying Network Node Server information. With this new capability, overall performance and operations should be improved because the preferred server is utilized more often. These improvements are achieved with minimal definition requirements.

    Simple Network Management Protocol (SNMP) Distributed Protocol Interface (DPI) Instance Level Registration: This new capability in CS OS/390 offers the opportunity to improve subagent performance by allowing subagents to register for management information base (MIB) objects for which they provide support at a more granular level. Customers may see improved performance because applications run multiple subagents, each of which can support particular instances of their MIB objects.

    X-Motif Data Link Libraries (DLL): DLL support for OSF/Motif applications is provided in CS OS/390 for the first time. Customers should see an appreciable reduction in the amount of DASD space required for each of these applications. As an example, a simple OSF/Motif application built without DLLs, requires over 5718 KB of storage. The same application, built with DLLs, requires a little over 49 KB of storage.

    TCP/IP Services Use of Cross System Coupling Facility (XCF): The use of XCF facilities by the TCP/IP stack was introduced in OS/390 Release 5. That capability was implemented by queueing the TCP/IP data to the APPN/SNA Service's address space. This extra step of queueing to the other address space is removed in OS/390 Release 6. This improvement should significantly increase the performance of TCP/IP over XCF.

    Virtual Private Network (VPN) Enhancement: Documentation has been enhanced to explain how to configure a secure tunnel between two communicating hosts such as, a client and OS/390, or between OS/390 and another server. Support has been added for the transport mode option of IPSec which is used pervasively when the secure tunnel is used to protect end-to-end communications between two hosts.

    Note: CS OS/390 customers who use or plan to use the High Speed Web Access (HSWA) capability, should note the following information regarding HSWA:

    High Speed Web Access: The technology developed for the HSWA facility, previously made available in Release 5 as a configurable option, has now been integrated into CS OS/390 Release 6 TCP/IP Services. Beginning with CS OS/390 Release 6, HSWA is no longer a configurable option.

    CS OS/390 Technology Demonstrations: IBM, a supplier of leading-edge eNetwork solutions for S/390, is delighted to be one of the industry's first to provide working prototypes of new leading-edge TCP/IP networking technologies for trial and evaluation by IBM customers and Independent Software Vendors (ISV). ReSerVation Protocol (RSVP) can enable users to confirm and reserve network resources (for example, bandwidth, buffers, etc.) for applications where and when necessary to help achieve a desired level of performance. IPv6 is the next generation evolution of Internet Protocol technology. It provides many technological improvements which are necessary to address the needs of an exponentially growing arena -- the Internet.

    These technology demonstrations are not part of CS for OS/390 Release 6 or any OS/390 release. They are only available through the Internet and are offered on an as is basis without warranty of any kind. IBM expressly disclaims all warranties, expressed or implied, including the implied warranties of merchantability and fitness for a particular purpose. The terms and conditions for use of these demonstrations is contained in the license agreement and function description on the Web pages along with the code.

    CS OS/390 provides these prototypes to enable S/390 customers to familiarize themselves with these exciting new technologies and to evaluate their benefits by using them in prototype or test environments with their own applications and networks. Another IBM objective is to receive feedback from users to help assess the demand for these functions as a formal part of CS OS/390. Additional information on the technology demonstrations is available at URL:

    ReSerVation Protocol (RSVP): If the customer is struggling with the challenge of having the bandwidth where and when they need it for specific applications, or they are tired of playing Russian Roulette with the Qualities of Service (QoS) provided to their TCP/IP users, RSVP may be the correct solution.

    RSVP can enable confirmation and reservation of network resources (for example, bandwidth, buffers) where and when necessary. RSVP makes network resource reservations on behalf of specific applications, for example those related to video, that need data delivered in a timely manner. RSVP executes resource reservations by propagating QoS parameters and installing these parameters in the network elements (for example, routers, switches) along the path. Having equipped the respective network elements with QoS parameters, RSVP enables customers to ensure the availability of route capacities necessary to support specific applications data flow requirements.

    Internet Protocol Version 6 (IPv6): Several of the key technologies defined by IPv6 have already been incorporated into CS OS/390 (for example, IPsec). Remaining, however, are such capabilities as expanded addressing, auto-configuration, quality-of-service, and enhanced security.

    Expanded addressing extends the address size from 32 bits to 128 bits, thereby supporting more levels of addressing hierarchy and a much greater number of addressable nodes that are necessary for growth. Also, autoconfiguration capabilities are provided which improves system programmer productivity by enabling more efficient configuring of IP networks. QoS capabilities are provided. They enable the labeling of packets belonging to particular traffic flows for which the sender requires special handling or priority. Enhanced security is provided by extensions which support authentication, data security, and confidentiality.

  • Cryptographic (ICSF) Services

    Enhanced ICSF support for Double-Key MAC: The ANSI X9.19 Optional Double-MAC Procedure is supported by ICSF and requires the use of a double-length key for MAC processing. This support addresses customer requirements for enhanced security for message authentication. Emerging VISA International and MasterCard protocols in Europe also call for ANSI X9.19 MAC. Generation of both user-derived keys and SESSION MAC keys is supported and Double-length MACVER keys are supported.

    Secure RSA Key Generation With Crypto: Secure RSA key generation is available with ICSF in OS/390 Version 2 Release 6. Keys can be generated in the TKE workstation and sent to the host where they are imported and used. This support conforms to the VISA and MasterCard requirements for RSA key generation for Payment Gateway. This support is available on OS/390 Version 2 Release 6 via PTF.

  • NetQuestion provides improved usability of the search forms and improved recoverability of the indexes. It now also enables customers to store NetQuestion workfiles in the /TMP directory of HFS. This enables NetQuestion to take advantage of the improved performance characteristics of /TMP when it is backed by the Temporary File System (TFS).

  • OS/390 Network File System (OS/390 NFS), formerly delivered as DFSMS/MVS (R) Network File System, has previously been available as part of DFSMS/MVS product (5695-DF1) and was also available as a nonexclusive element of the OS/390 product (5647-A01). Beginning with the OS/390 Version 2 Release 6, NFS is only available on OS/390 Version 2 (5647-A01). OS/390 NFS enhancements enable customer's OS/390 systems to become improved participants in their distributed enterprise. OS/390 NFS helps customers to achieve a UNIX-like system with the capacity, storage management, and reliability of OS/390. The new function includes the following productivity, usability, and performance enhancements:
    • SUN NFS Version 3 Protocol Support for Client and Server

      In addition to supporting the SUN NFS Version 2 protocols, the OS/390 NFS client and server is enhanced to support the SUN NFS Version 3 protocol specification, RFC 1813. Both versions coexist in this OS/390 NFS release. Some of the significant improvements resulting from the support of the SUN NFS Version 3 protocol include support of larger than 4 GB files and file systems by extension of 64-bit file sizes and offsets and performance modifications. The performance modifications that result in more efficient use of the network are:

      • File attributes are included with every operation. This eliminates the need to send separate RPC requests for updated file attributes. Therefore, fewer RPC requests are required to go across the network.

      • The transfer size is increased. The maximum packet size is increased from 8 KB to 64 KB. Therefore, large files can be transferred across the network in fewer packets.

      • Safe/unsafe writes are supported. Safe writes require the server to wait until the data is written to stable storage before returning to the client. Unsafe writes enable the server to acknowledge receipt of the data before actually writing to stable storage. When a commit is issued from the client, OS/390 UNIX hierarchical file system (HFS) files are written to stable storage. When a commit is issued for MVS conventional datasets, the server responds, but writes a complete record to stable storage at write-timeout. Therefore, unsafe writes enable data to be sent across the network at shorter intervals than with safe writes.
    • Validated Support of NFS Version 3 Clients

      With the enhancement of SUN NFS Version 3 protocol, the client-enabling code (MVSLOGIN, MVSLOGOUT, and SHOWATTR) has been ported and verified to the platforms listed below. This code enables the NFS Client to login to or logout of the OS/390 Network File System server. However, this client-enabling code is not provided for the Windows (TM) platform. The login authentication is included with the vendor's Windows package through the use of PCNFSD.

      The following additional NFS Version 3 protocol clients have been verified with the OS/390 NFS server:

      • AIX (R) 4.2 NFS
      • Intergraph DiskAccess for Windows NT Version 3.0 NFS
      • OS/390 2.6 NFS
      • Solaris 2.5.1 NFS
    • TCP Transport Support for the Server

      OS/390 Network File System supports TCP (Transmission Control Protocol) as a transport, in addition to UDP (User Datagram Protocol) for the server for both NFS Version 2 and Version 3 protocols. UDP is primarily used for its efficiency on high-bandwidth, low-latency networks, for example, LAN. However, the number of NFS implementations that use TCP is growing because customers want to benefit from its efficiency on low-bandwidth, high-latency networks, such as the Internet or WAN.

      Another inherent benefit of TCP is the connection reliability characteristics of the protocol. Consequently, corporate Internet firewalls accept TCP packets but typically block UDP packets to their intranets.

      The OS/390 NFS server supports the TCP protocol for the NFS, MOUNT and MVSMOUNT programs, and the client enabling code: MVSLOGIN, MVSLOGOUT, and SHOWATTR. This is supported for both NFS Version 2 and Version 3 protocols.

    • WebNFS Server Support

      OS/390 NFS is enhanced with the WebNFS capability. The WebNFS protocol is an extension of the SUN NFS Version 2 and Version 3 protocols, RFC 2054 and 2055. This enhancement enables a customer's Java applications to exploit the NFS file sharing capabilities. The following are some of the significant WebNFS functions:

      • The PORTMAP protocol overhead is eliminated. Because the NFS TCP port of 2049 is defacto, there is no need to query the PORTMAPPER for the NFS port. The client connects directly to port 2049.

      • The MOUNT protocol is also eliminated with the use of public filehandles. Normally, a client issues a MOUNT to obtain the filehandle -- the identification of a file pathname. The public filehandle content (zero or empty) is already known by the client, so there is no need to issue a MOUNT.

      • With the elimination of the overhead associated with the PORTMAP and MOUNT protocols for WebNFS, the first operation sent across the network is LOOKUP. The number of LOOKUP requests required to identify a particular file on the server is reduced. This is accomplished with the multi-component LOOKUP capability. Instead of submitting a LOOKUP for each component, or directory level, of a pathname, the server evaluates the entire pathname in the first LOOKUP.

        Both types of pathnames are supported: absolute pathname and relative pathname. The new capability of handling the relative pathname is supported with the use of a new site attribute, public(pathname).

      • Retransmitting entire files is eliminated if the communication connection is broken. Since NFS breaks the files into smaller reads/writes, the NFS client continues to transmit requests from the last successful request before the break.
    • Filename Extension Support for PDS/PDSE

      The OS/390 NFS server now enables an NFS client to specify default OS/2 (R) filename extensions for MVS PDS and PDSE members that are mounted by any client workstation that supports the NFS protocol, such as OS/2. This provides customers with seamless access to MVS PDS and PDSE members and enables them to develop on a workstation platform for execution on OS/390. This usability enhancement enables application developers to remotely edit/compile/debug their applications with workstation-based productivity tools.

      This enhancement provides products, such as VisualAge (R) COBOL, C++, and other compilers support for remote MVS application development capability. The support enables mapping of MVS member filenames to/from workstation names, for example, PDS member COBOL.APPLET1(DATADEF) to DATADEF.CBL under directory COBOL.APPLET1 so that workstation tools (for example, editors and compilers) can process host files without modifications.

      The filename extension length can be up to eight bytes for PDS and PDSE members. This filename extension mapping capability (translation between the real MVS member name and the workstation file name) is provided by the use of a side file on the MVS host specifiable by the system administrator and/or NFS end user during a MOUNT operation. The NFS server manages the loading/unloading of side files to maximize the use of storage for side files.

    • NFS Server Support for NLM/NSM Locking Protocols (LOCKD/STATD)

      The NFS protocol is a stateless service. Therefore, it cannot provide inherent stateful services, such as file locking and access control synchronization. Instead, these services are provided by two cooperating processes: the Network Lock Manager (NLM) and the Network Status Monitor (NSM). The NLM and NSM are RPC-based servers which normally execute as autonomous daemon servers on NFS client and server systems. They work together to provide stateful file locking and access control capability over NFS. This support enables CATIA applications to access OS/390 HFS files.

      NLM PROTOCOL(LOCKD): The NLM is a service that provides advisory byte-range file and record locking, and DOS-compatible file sharing and locking in an NFS environment.

      NSM PROTOCOL(STATD): The NSM is a service that provides applications with information on the status of network hosts. The NSM keeps track of its own state and notifies any interested party of a change in this state. The state is merely a number which increases monotonically each time the condition of the host changes. An even number indicates the host is down, while the odd number indicates the host is up.

      The NSM does not actively probe hosts it has been asked to monitor. Instead, it waits for the monitored host to notify it that the monitored host's status has changed, that is, crashed and rebooted.

    • Performance Enhancements

      OS/390 Version 2 Release 6 NFS server performance exhibits up to*:

      • 55% less CPU time per NFS operation
      • 45% better throughput for Reads
      • 75% better throughput for Writes
      These comparisons were made against OS/390 Version 2 Release 4 with DFSMS/MVS Version 1 Release 4 NFS and TCP/IP V3.2 for NFS Version 2 protocol throughout. CPU time was determined by comparing a mix of NFS operations.

      NFS server's internal algorithms have been redesigned to provide reduced pathlengths. The pathlength reductions are most apparent for HFS file access with SUN NFS Version 2 protocols. Customers will see improved CPU time per NFS transaction. NFS server has also increased throughput for HFS file accesses by means of improved internal serialization algorithms.

      Use of SUN NFS Version 3 protocols provides performance modification over SUN NFS Version 2 protocols. These are described in the SUN NFS Version 3 Protocol section above.

*     The above listed performance measurements for TCP/IP under the
      eNetwork Communications OS/390 section and for NFS were derived
      by IBM in a controlled environment.  A customer's actual
      performance results may vary significantly.  Accordingly, IBM
      provides no representations or assurances that a customer will
      achieve the performance results that are contained in this
      announcement.



S/390 APPLICATIONS INITIATIVE

The goal of the S/390 Applications Initiative is to deliver new applications, new infrastructure in support of programming environments, and new support for application growth through tools for S/390 and OS/390. The Applications Initiative's customer-driven focus is based on object-oriented Component Broker technology, UNIX and OS/390 UNIX technology, and technologies that optimize application development, porting and execution while delivering a low-cost hardware and software platform solution.



S/390 Applications Initiative Release 6 Items

  • Component Broker for OS/390

    In May 1997, IBM announced the plan to deliver its strategic object-oriented application development environment. Component Broker was announced as rolling out over time on multiple platforms. Component Broker planning progress appeared in the previous two OS/390 Release 4 and Release 5 Availability announcements. Refer to Software Announcement 297-355 dated September 9, 1997, and Software Announcement 298-049 dated February 24, 1998.

    In the OS/390 Release 6 time-frame, IBM is following through on that announcement to make Component Broker available on the S/390 platform. Initially, this was done for a limited set of customers participating in concept validation on OS/390 Version 2 Release 5. Because customer demand for this technology and because customers have told IBM that they want to begin working with the functions as soon as possible, a Beta program for Component Broker on OS/390 will be opened up to all interested customers in December 1998. Component Broker for OS/390 will be available at no additional charge for those customers with OS/390 Version 2 Release 5 or 6.

    Component Broker will be made available to interested customers through a registration process. The specific details will be announced prior to CB availability. IBM is making Component Broker available so customers may begin using this new technology on the S/390 platform.

    Component Broker for OS/390 will provide an environment for the hosting of new business applications on S/390 that, using a new programming model, will enable customers to rapidly design and develop their applications. This programming model will be the same across platforms. This environment will continue to evolve on S/390 to include access to all of the S/390 qualities of service and access to more and more of the established resource managers for data.

    Component Broker for OS/390 will leverage S/390 strengths, such as Parallel Sysplex technology for scale and availability, and will exploit the OS/390 Workload Manager for proper workload balancing and management. This will enable Component Broker work to coexist with traditional workloads, such as IMS and CICS.

    Additional information concerning Component Broker for OS/390, can be found on the World Wide Web at the OS/390 home page and the Component Broker Home page at URL:

  • Language Environment for OS/390

    Language Environment Performance: HEAPPOOLS is a Language Environment run-time option that enables the usage of a new heap storage management algorithm. This algorithm not only has a shorter path length for most storage requests, but also virtually eliminates contention for storage latches in a multi-threaded environment. Because of these two features, customers can significantly improve the performance of their applications that use heap storage.

    Customers are able to filter out informational messages from the MSGFILE using the new run-time option, INFOMSGFILTER. This benefits customers who migrate their application programs to run under Language Environment. This function reduces the number of messages received and improves performance.

    Customers benefit from path length reduction in the functions of fopen(), fclose(), stcoll(), wcscoll(), fork(), exec(), spawn(), bcopy(), sprintf(), and vsprntf().

    Language Environment RAS: Various enhancements are made to IPCS and CEEDUMP formatting to better enable customers to obtain complete first failure data capture. Updated 408x abend messages include additional failure data. Also, customers have the option to suppress Language Environment informational messages and have CEEDUMPs written to a user-specified directory.

    Application programmers receive assistance in debugging their application programs through _CEE_DMPTARG. This new environment variable determines the location of CEEDUMP.

    IEEE Floating Point Support: Support is added to the C/C++ runtime library to enable C/C++ applications to use IEEE floating point. This support includes IEEE math library functions, printf and scanf support for IEEE floating point data, and support for 16 floating point registers for both IEEE floating point and the current S/390 floating point. Support is available through the following APARs: PQ16086, PQ16069, PQ16948, and PQ16949.

  • OS/390 UNIX System Services (OS/390 UNIX)

    Performance Improvements: Multiple performance improvements are made in OS/390 UNIX. Customers receive faster process creation and reduced storage usage for servers that exploit Multiple Process Multiple User Support. Through Shared Memory, customers can now share large segments of memory without any increase in system resource usage. Customers also receive a reduction in storage requirements when memory mapping large files. MMAP adds new segment-level paging support where megabyte multiples on megabyte boundaries are shared.

    Customers now have a high-performance implementation of binary semaphores. Binary Semaphore exploits the Perform Locked Operation (PLO) hardware instructions and eliminates latching in semaphore processing. A customer must have a CMOS system to realize the full performance benefits of this capability.

    Customers achieve performance improvements through the optimization of the Logical File System (LFS). This has been achieved by enabling a pre-built environment to persist across multiple file system requests. NFS, in particular, achieves path length savings because of this new support.

    OS/390 UNIX Shell and Utilities: Customers receive the benefit of improved OS/390 Shell and Utilities performance through its recompiling with IPA optimization. Additional performance improvement is available because path lengths are improved for multiple utilities. Server applications can now dynamically manage processes through the new _pid_affinity services.

    Socket Functions: Several new socket functions are being introduced to help improve the performance of major OS/390 UNIX products:

    • accept_and_recv() -- Combined accept() and first receive()

    • receive with timer -- Receive() with a timeout capability

    • open_stat() -- Combined open() and fstat()
    Socket support for Communications Storage Manager (CSM) buffers provides a facility for programs to avoid data moves in a communications session. Buffer ownership is transferred instead of copying the buffer contents. The srx_np(BPX1SRX) Callable Service enables CSM buffers to be used to send and receive data on a socket.

    IEEE Floating Point Support: Base OS/390 UNIX System Services adds support for the IEEE floating point hardware. The OS/390 UNIX Debugger is enhanced to support debugging of C/C++ programs using IEEE floating point and 16 floating point registers. The od command in the OS/390 Shell and Utilities adds support for IEEE floating point data. The OS/390 UNIX Debugger support is available through APAR OW33857. The enhancement to the OS/390 Shell and Utilities for IEEE can be obtained through APAR OW33254.

  • C/C++

    The C/C++ feature of OS/390 Version 2 Release 6 has the following enhancements:

    IEEE Floating Point Support: The C/C++ compiler adds support for IEEE floating point in the S/390 environment. Applications that use floating point can now be more easily ported from other platforms to S/390. These applications may also be able to take advantage of the new S/390 Generation 5 Server to extend the range and precision of data in scientific calculations. With the new S/390 Generation 5 Server, C/C++ applications, including those using the current S/390 floating point, can improve performance by being recompiled to enable use of 16 floating point registers.

    64-bit Integers (Long Long) Support: Support for 64-bit integers (long long) data type has been added to the C/C++ compiler to extend the precision of data in calculations and to provide easier portability of applications with these data types from other platforms to the S/390 environment.

    Enhanced Binary Coded Decimal Class Libraries: The Binary Coded Decimal class libraries have been enhanced for C/C++ to provide improved performance and compatibility with the C, PL/I, COBOL, and Assembler packed decimal data type.

    Class Library Header Installed in HFS Directories: The class library headers are now installed in HFS directories as well as in PDSs. This enables OS/390 UNIX System Services developers to view the header files and to provide consistency with other header files.

    alloca() Built-in Function: The alloca() built-in function has been added for system management of stack storage and for easier portability of applications from other platforms to the S/390 environment.

    Single Optimization Level: OPTIMIZE(1) and OPTIMIZE(2) has been converged into a single, effective optimization level.

  • High Level Assembler (HLASM)

    Support for IEEE floating point and 16 floating point registers is provided in the stand-alone High Level Assembler Version 1 Release 3 product (available at no additional charge to OS/390 licensees) and the High Level Assembler Toolkit Version 1 Release 3 (available at no additional charge to OS/390 HLASM Toolkit licensees) which will be available September 1998. For more details, refer to Software Announcement 298-271 dated July 28, 1998. This level of the HLASM product is planned to be integrated into OS/390 Release 7.

  • IMS Open Transaction Manager Access (OTMA) Callable Interface

    The IMS OTMA Callable Interface, available as part of a stand-alone product that runs with OS/390 Release 6, provides a high-level interface for access to IMS applications from other OS/390 subsystems. It presents an API to a C or C++ program to enable access and execution of IMS transactions through IMS OTMA facilities. With this simple and easy-to-use interface, the invoker of the APIs can submit a transaction or command to IMS from within the OS/390 environment without the necessity of understanding the more technical protocols of the MVS Cross Coupling Facility (XCF) or the IMS OTMA. This function is planned for delivery through the service process by December 1998.

  • OS/390 Application Enabling Technology Enhancements (OS/390 AET)

    OS/390 AET provides the base technology to create an easy-to-use, automated OS/390 UNIX application server. OS/390 AET is further enhanced with capabilities to make it easier to provide an OS/390 UNIX Systems Services (OS/390 UNIX) environment that can be used and administered with minimal need for OS/390 skill. OS/390 AET is offered as a base element of OS/390 for customers to customize and tailor their own automated UNIX applications server. OS/390 AET is also the basis for the IBM solutions: Application StarterPak -- Preloads 2 and 5; and the OS/390 Automated UNIX System Option.

    DB2 for OS/390 is the database of choice for many OS/390 UNIX applications, especially for ERP applications. In normal OS/390 operations, all DB2 administration and some DB2 application development tasks require access to TSO and batch. OS/390 AET now supports access to DB2 from the OS/390 UNIX command shell, further reducing the need for OS/390 skill when managing OS/390 UNIX applications. DB2 application development and DB2 administration can be accomplished from the OS/390 AET environment. SQL statements, DB2 commands and DB2 utilities, as well as the DB2 pre-compiler can be launched from the OS/390 UNIX shell.

    Installing OS/390 UNIX applications often requires operations, such as allocating HFS data set, identifying modules to be preloaded in the LPA, or updating PARMLIB members. HFS allocation on user-controlled DASD volumes via OS/390 UNIX commands was introduced in the AET element in OS/390 Version 2 Release 5. In OS/390 Release 6, OS/390 AET is extended to provide the capability to add or delete modules or DLLs from the dynamic link pack area (LPA) directly from the OS/390 UNIX command shell. This minimizes the OS/390 skill needed for installing and maintaining OS/390 UNIX applications. In particular, it is possible to install and maintain Lotus Domino for S/390 just using UNIX skills and to perform a fast-start without requiring additional OS/390 knowledge.

    Web-based TCP/IP Configuration: TCP/IP is the most often used communication vehicle for UNIX applications, making a working TCP/IP configuration critical for UNIX application availability. In normal OS/390 operations, maintaining the TCP/IP configuration involves editing multiple OS/390 UNIX files with the relevant parameters, with little to no guidance for the available options and their meanings. In Release 6, OS/390 AET provides a Web-based, intuitive GUI for TCP/IP. It hides complexity and helps to avoid definition errors by value checking and cross checking. It is based on and coexists with the administration interfaces that are used today for TCP/IP configuration.

    Automatic Restart: OS/390 AET enables a system to be defined that, to a large degree, runs unattended. In Release 6, the OS/390 AET control center is enhanced to detect when the OS/390 system enters a not-operational state, and automatically restarts the system, further increasing availability.

    LDAP (Lightweight Directory Access Protocol) Client Support: In Release 6, OS/390 AET introduces support for Client Access (TM) to directory services that accept the LDAP protocol. This enables programs, that run on OS/390 UNIX, to enter and extract information into and from an LDAP directory service. OS/390 AET contains the LDAP V3 client function and a sample of how it can be used.

  • OS/390 Ease-Of-Use Capabilities For UNIX-Based Applications

    An easy-to-use OS/390 Automated UNIX System Option will be available as an additional OS/390 delivery vehicle during the OS/390 Release 6 time-frame for an additional charge. This new delivery option is intended to provide a UNIX application platform that is easily installed and designed to not require any OS/390 system programming skills for management or maintenance. It can provide a low total-cost-of-computing solution for small remote or departmental solutions in large enterprises.

    Typical OS/390 UNIX-based applications include:

    • Web content hosting

    • Secure network computing applications

    • e-business applications

    • Lotus Domino for S/390

    • The ability to develop, port, and run generalized UNIX interactive workloads that take advantage of the OS/390 UNIX Hierarchical File System (HFS) and DB2

    • Consolidation of alternate platform UNIX application workloads on S/390
    The easy-to-use OS/390 Automated UNIX System Option objective means that no OS/390 (MVS) systems programmer or operator skills to install, maintain, or use it are required. Some of the systems administration tasks, such as system install, system refresh, and TCP/IP configuration, are accomplished using a new GUI approach. The other tasks, such as user and password administration, PTF maintenance, and file system maintenance, will only require some basic UNIX administration skills.

    This additional OS/390 delivery vehicle option will be pre-built and configured by IBM utilizing OS/390 Application Enabling Technology (AET). All required system programming and set-up is already included in this delivery option. It will be delivered in an easy-to-install dump restore (DDR) format and will run either stand-alone, in an LPAR, or as a guest system of VM/ESA (R). Special IBM-supplied software service support, a Front End Support Team (FEST), will be available to assist in problem determination and problem source identification (PD/PSI) work to determine fixes a customer may require. Easy-to-use commands will provide the application of selected service without the need for traditional OS/390 systems programmer skills. Large OS/390 or MVS enterprise customers, who prefer to do their own software servicing of these departmental or remote systems from the central site, will continue to have that option available.

    This additional OS/390 delivery option is not meant to replace existing OS/390 systems. It is offered as another option for large enterprise customers who have departmental or remote non-S/390 systems, but require the security, scalability, availability, and robust Qualities of Service (QoS), which have long been the hallmark of S/390. This is a particularly valuable option where the necessary OS/390 skills to install, run and, support the desired OS/390 UNIX-based applications do not physically exist at the departmental or remote site where the OS/390 solutions are installed and run.

    This new additional OS/390 delivery vehicle option supports the industry trends of server consolidation, network computing, e-business, and application enablement.



S/390 Technology Leadership Initiative

S/390 provides an infrastructure of hardware, software, and Parallel Sysplex technology that responds quickly and easily to dynamic customer requirements and new opportunities. S/390's enhanced leading-edge technology integrates software and hardware functions to offer comprehensive end-to-end (from small to very large) enterprise solutions required in today's extremely fast-paced and competitive business environments. These capabilities are the defining standard in enterprise computing, and are the focus of the S/390 Technology Leadership Initiative.

In today's world of mega-mergers (for example, banks), S/390 hardware running OS/390 provides the necessary muscle (compute power, scalability, security, and availability) to assist these companies to survive. These companies face increased need to handle many different types of complex mission-critical workloads from multiple companies simultaneously, with industry-leading 24 x 7 x 52 type availability that is provided by Parallel System technology, with improved management characteristics, and with industry-leading scale and security. While, at the same time, these flexible solutions also facilitate operations at the department or small unit level, thereby supporting both enterprise information integration and any necessary small unit independence.

S/390 products are built on industry-leading technologies designed to exploit and expand the growth projected in both traditional and new server environments. S/390 provides the foundation for business solutions and secure network computing, while integrating leading-edge technology that enables end-to-end enterprise solutions.



S/390 Technology Leadership Initiative Release 6 Items

  • Parallel Sysplex Technology

    IBM continues to enhance Parallel Sysplex -- S/390's industry-leading clustering technology. New functions in OS/390 Version 2 Release 6 reduce complexity for certain coupling facility management situations and enhance the Coupling Facility (CF), and, therefore, Parallel Sysplex technology availability.

    Rebuild for CF Maintenance: Today, customers who cause CF structures to be moved, for example to upgrade a CF, find that it is difficult to restore structures to the enhanced configuration when the upgraded CF is restored to the configuration. New CF function in OS/390 Release 6 enables a method to populate a coupling facility from the set of allocated coupling facility structures after one or more coupling facilities have been added (or restored) to the configuration. This substantially reduces systems management and operational complexity for customers' system programmers and operations staff.

    Cache Structure User-Managed Duplexing: A mechanism is added to the CF to give customers the option of having cache structure data duplexed in another CF under the control of the CF-exploiting subsystem or product. Initial exploitation of this capability by DB2 supports the duplexing of data contained in its group buffer pool (GBP) structures. This duplexing capability enables extremely fast fail over from one copy of the structure data to the other in the event of a CF failure or, more typically, a planned CF outage. This duplexing fail over operates much more quickly than today's mechanisms. Furthermore, the new duplexing mechanism handles some failure situations that are currently not handled. This significantly enhances the availability characteristics of the data contained in these duplexed structures. It improves the availability of those Parallel Sysplex workloads that exploit this capability.

    Cluster Bus Links: OS/390 is providing Parallel Sysplex software support for the new cluster bus links that are available on S/390 Generation 5 servers. This support is available via an SPE on OS/390 Release 3 and higher (APAR OW28556).

  • Base Control Program (BCP) Core Component Enhancements

    Components within the BCP have been changed to support the S/390 goals. Specifically, these changes affect areas such as Allocation, Scheduler, SMF, and Operations. Enhancements enable national characters in CONSOLxx suffix, issue EOT DOM only if the task has issued messages, and enable dynamic reconfiguration of console devices.

    Allocation has been changed to remove the BCP architectural limit of 10,000 concurrent dynamically allocated DB2 data sets. This change, in combination with a DB2 V5 APAR change, is intended to help address a scalability concern of customers (particularly banks in Europe). This change also, in combination with a DB2 V5 change, enables DB2 customers to use more than 10,000 dynamically allocated data sets to define their DB2 data bases.

    IEEE Floating Point: The BCP is enhanced to support the new IEEE floating point hardware (ANSI/IEEE Standard 754-1985, IEEE Standard for Binary Floating-Point Arithmetic) in the S/390 Generation 5 Server. This enables programs running on OS/390 Release 6 to use the IEEE floating point instructions and 16 floating point registers. In addition, the BCP provides simulation support for all the new floating point hardware instructions. This enables applications that make light use of IEEE floating point, and can tolerate the overhead of software simulation, to execute on OS/390 Release 6 without requiring an S/390 Generation 5 Server.

    DUMP Command PARMLIB Support: This support enables DUMP command parameters to be supplied via PARMLIB member. Customers can use canned complex dump parameters to quickly specify commands when performing Parallel Sysplex technology problem determination. Customers can improve their use of the DUMP command to collect multi-address space and multi-system dumps by specifying a PARMLIB member on the DUMP command -- one that contains the DUMP command parameters.

    Display Logger Command (Full Support): The enhanced Display Logger command improves a customer's ability to perform a Parallel Sysplex-wide systems management of the MVS System Logger and its related log streams. This enhancement includes the ability to determine the following systems management aspects for Parallel Sysplex technology:

    • The operational status of the Logger address space

    • The status of log streams connections on the system where the command is issued

    • Support for planned reconfigurations

    • Capability to determine Parallel Sysplex-wide information about log stream usage

    • Capability to determine the utilization of list structures that are assigned to log streams
    Logger Serviceability: Enhanced Logger serviceability provides additional diagnostic information and data capturing that improves analysis and fixes time-related System Logger problems.

    DASD Logger Offload Support: System Logger log stream offload processing is significantly improved because the logger now performs offload operations asynchronously, overlaps operations, and more efficiently utilizes the I/O subsystem interfaces. These changes result in the offloading of an increased amount of data and make resources available more quickly so that more transactions can complete in a given time frame. This improvement enables the IMS V6 Shared Message Queue Function to support customers' large Parallel Sysplex technology requirements.

  • Workload Manager

    Discretionary Goal Management: Customers have asked for improved WLM management of discretionary work when it coexists with more important work. WLM is now more aggressive in giving resources to discretionary work, as long as all more important work is meeting goals. This enables some customers to assign a wider range of work to a discretionary goal because it is less likely to be shut out by more important work that is overachieving goals. Assigning as much work as possible to a discretionary goal is desirable because it gives WLM the most latitude in efficiently managing resources.

    Service Definition Comments: This enhancement addresses one of the highest priority customer requests for WLM by extending the WLM administrative definitions to permit customer inclusion of additional descriptive commentary. The WLM administrative application provides new input fields associated with work classification rule definitions and work classification group definitions. This new information is saved in the WLM service definition.

  • JES3

    DUMP JOB Enhancements: DUMP JOB runs the tape I/O portion of Dump Job DSP in its own address space. Prior to Release 6, to use Dump Job, the installation must define a tape device in the JES3 initialization stream via a DEVICE statement. This requires a JES3 warm start if the required device is not currently defined in the JES3 initialization stream. With the new support, any tape drive in the system can be used, even if the tape device is not defined to JES3.

    Because the tape I/O portion runs in its own address space, a data set is cataloged which contains the list of volumes that are used to dump the jobs to tape. This makes it easier to keep track of which tape volumes are needed when the jobs are to be restored from tape. In addition, OPEN and CLOSE are used to open and close the tape data set so tape management products, such as RMM can be used to manage the tapes.

    Resource affinity exploits the resource affinity support introduced by WLM in OS/390 Release 4. The installation defines a set of (abstract) resources and groups one or more of these resources into scheduling environments. If a job is associated with a scheduling environment, JES3 will only schedule the job to those systems where the scheduling environment is available.

    Changing JES3 LPA Modules without an IPL: With OS/390 Release 6, JES3 LPA modules can be changed without an IPL and CLPA being performed. A new level of JES3 LPA module is activated when a JES3 hot or local start (without IPL) is performed. JES3 automatically picks up the new levels of the module during JES3 initialization.

  • IOS Channel Path Recovery Availability Improvements

    In OS/390 Release 6, IOS maximizes system availability by reducing the use of synchronous WTOR processing by issuing Channel Path and Hot I/O recovery messages via asynchronous WTOR processing. Channel Path and Hot I/O recovery actions are enhanced to avoid having to enter Channel Path Recovery for certain device classes. The need to disable sharing systems is eliminated if Channel Path Recovery cannot be avoided and is required to recover the affected device(s).

  • S/390 Open Systems Adapter 2 (OSA-2)

    The OSA-2 feature supports 100 Megabits per second (Mbps) Ethernet (Fast Ethernet) for higher speed connectivity in the Ethernet environment. This feature utilizes the same packaging as the current OSA-2 features, plugging directly into a standard I/O slot, making it an integral component and enabling convenient Local Area Network (LAN) attachment. The Fast Ethernet OSA-2 feature provides direct access from the S/390 server to high-bandwidth and high-capacity campus LAN backbones. It can be a cost-effective solution to help satisfy network performance problems. Refer to Hardware Announcement 198-040 dated February 24, 1998, for more detail on the new Fast Ethernet OSA-2 feature.



ADDITIONAL INFORMATION ON OS/390 VERSION 2 RELEASE 6



Security and Directory

The Security and Directory capabilities of OS/390 continue to be a key strength of the platform. Security function is found in both the OS/390 base product and in the OS/390 Security Server.

The OS/390 Security Server, an optional feature of OS/390, works closely with OS/390 system software and other products that support the IBM Security Architecture. It continues to expand to meet customer needs for robust security and directory capabilities. OS/390 Security Server includes:

  • RACF
  • DCE Security Server
  • Firewall Technologies
  • LDAP Server Support
OS/390 Base Services include an LDAP client for OS/390 and basic Firewall Technologies.

ICSF, also in the OS/390 base, serves as an interface to the Cryptographic Coprocessor hardware. Together, they provide support for a wide variety of cryptographic standards and functions.

Enhancements to OS/390 Base Services and the OS/390 Security Server in OS/390 Release 6, continue to position the platform to help meet the security and directory requirements for a customer's entire enterprise. IBM will continue, in future OS/390 releases, to help meet customer needs for a robust public key infrastructure and keep pace with the developing Internet and e-business requirements. (Refer to the OS/390 Version 2 Release 7 section of this announcement for more information about future enhancements.)

Where To Find More Information: Information about a complete range of security issues, standards, and IBM solutions are found on the SecureWay (TM) Web site at URL:

There is now a S/390 security Web site at URL: The RACF home page can be found at URL: OS/390 Release 6 Security and Directory Enhancements

RACF Digital Certificate Enhancement: Users can currently access information on an OS/390 server via the Internet using the WebSphere Application Server for OS/390 (formerly delivered as Domino Go Webserver). Security is created between the client workstation and WebSphere Application Server for OS/390 using digital certificates for authentication. In OS/390 Version 2 Release 4, security services for Web-computing were integrated with the OS/390 Security Server by enabling RACF to accept digital certificates authenticated by WebSphere Application Server for OS/390 without requiring a RACF userid and password for each client when Web pages were accessed. This change eliminated the need for the client to be authenticated multiple times.

In OS/390 Release 6, that support is enhanced by providing the ability for certificates to be automatically authenticated to RACF. An administrator no longer manually transmits (using the RACDCERT command on TSO) the client certificate to OS/390. A registration page prompts for registration of the user's certificate and RACF userid. When the user clicks on the registration box, a secure session is set up. The certificate is automatically installed when first presented by the client.

Many industries now conduct business transactions over the Internet. This key challenge has been to leverage existing Information Systems (IS) systems and data in order to conduct business safely. IBM is stepping up to this challenge on OS/390 by simplifying access to business critical information by others and providing effective and manageable control over access to IS resources. The digital certificate enhancements in OS/390 Release 6 will be another step in IBM's continuing plans to provide a complete robust public key infrastructure and integrate Web applications with seamless control over access to critical information.

This support will also be available back to OS/390 Release 4 and Release 5 via PTF.

RACF Administrative Enhancements: RACF userid administration is more efficient in OS/390 Release 6 because of the new ability to reset passwords, resume userids, and list users without requiring the RACF SPECIAL or group-SPECIAL attribute. Security administrators have the ability to control who is allowed to perform these functions through profiles in the FACILITY class. This support enables greater granularity of control for customer installations. It is especially useful in a help desk environment where only partial authority is required and it does not override current authorization mechanisms. It is available back to OS/390 Version 1 Release 3 and Version 2 Release 4 and Release 5 via PTF.

In addition, administrators can now reset a user's password without requiring that the user change it upon first use. A new option (NOEXPIRED) on the ALTUSER command enables customers to specify a new password value that does not have to be changed upon first use. This support is also available back to OS/390 Version 1 Release 3 and Version 2 Release 4 and Release 5 via PTF.

Removing class authority has also been made easier in OS/390 Release 6. It is now possible to specify NOCLAUTH on the RACF ALU command for a class that does not exist in the Class Descriptor Table (CDT).

Transportable Access Control Environment Elements (ACEEs) with RACF: Support for the RACF Environment Object is extended, such that retrieval, construction, and transportation of security environments across address spaces or on another system in the Parallel Sysplex environment is simplified.

This support is provided through enhancements to the RACROUTE REQUEST=EXTRACT macro and the INITACEE callable service. Component Broker technology available with OS/390 can utilize this function.

RACF Support For Network Qualified LU Names Enhancements: The restriction that network LU names be unique across interconnected networks is removed. The ability to specify an additional qualifier in APPC information passed to RACF to identify the remote network in existing APPCLU and APPCPORT classes has been added. Customers with interconnected networks that contain the same LU names are now able to differentiate them. A 17-byte network qualified name is now supported. This support increases the flexibility of communication and the use of resources among networks.

RACF Support For OS/390 UNIX Enhancements: It is now possible for an existing OS/390 UNIX process to create a new security identity without creating a new address space. RACF has been updated to support this capability of having multiple processes and multiple users in a single address space. Customers can more easily port applications to OS/390 that may already be in use on other platforms. This can increase the usability of these applications, in addition to making a more scalable environment available.

In addition, auditors have the ability to determine when a user is a superuser and determine the identity of the user. A new function code (via SMF type80) enables a full audit trail that can be used to ensure adequate security.

RACF Interface Enhancements (Support for Tivoli Products): The OS/390 Security Server for Release 6 has been enhanced to provide the programming interfaces which enable RACF to be managed by other applications. All RACF user segments are supported by Tivoli User Administration for OS/390 (which works with Tivoli User Administration) to manage users throughout the enterprise. In addition, RACF groups and resources are supported by Tivoli Security Management for OS/390 (which works with Tivoli Security Management) to manage groups and resources throughout the enterprise. These two Tivoli applications will support OS/390 (RACF) via the Tivoli Management Agent during the fourth quarter 1998.

The RACF R-admin callable service is updated to support adding, altering, deleting, and listing data set and general resource profiles. Also, a function code is added to enable a user or group to be permitted access to a data set or general resource.

This support improves the usability of resource access management of RACF. In addition, the capability to manage RACF with applications that can also be used on other platforms, such as the Tivoli products, can result in cost savings for security administration. An administrator needs to become proficient with only one set of user dialogs and administration methodologies.

For more information about the Tivoli products, refer to the Tivoli Web site at:

Enhanced ICSF Support for Double-Key MAC: The ANSI X9.19 Optional Double-MAC Procedure is supported by ICSF. This requires the use of a double-length key for MAC processing. This support addresses customer requirements for enhanced security for message authentication. Emerging VISA International and MasterCard protocols in Europe also call for ANSI X9.19 MAC. Generation of both user-derived keys and SESSION MAC keys is supported. Double-length MACVER keys are supported.

Secure RSA Key Generation With Crypto: Secure RSA key generation is available with ICSF in OS/390 Release 6. Keys can be generated in the TKE workstation and sent to the host where they are imported and used. This support conforms to the VISA and MasterCard requirements for RSA key generation for Payment Gateway. This support is available on OS/390 Release 6 via PTF.

Firewall Technologies Enhancement: The Virtual Private Network (VPN) support is being enhanced to enable a VPN tunnel to be configured between a client and the OS/390 server and between the OS/390 server and another server. The IPSec AIX Client shipped with AIX and the IPSec Windows 95 Client Shipped with the eNetwork Communications suite are supported. This broadens the VPN support from Firewall to Firewall to enable tunnels to clients and other servers.

Documentation has been enhanced to explain how to configure a secure tunnel between two communicating hosts, such as a client and OS/390, or between OS/390 and another server. Support has been added for the transport mode option of IPSec which is used pervasively when the secure tunnel is used to protect end-to-end communications between two hosts.

The FTP proxy's performance is being improved by adding multi-thread support. This multi-thread enhancement has also been added to OS/390 Version 2 Release 4 and Release 5 with APAR OW31516. Other performance improvements are being made to improve the performance of all the Security Server's Firewall Technologies.

Lightweight Directory Access Protocol (LDAP) Client Support: In Release 6, OS/390 AET introduces support for client access to directory services that accept the LDAP protocol. This enables programs that run on OS/390 UNIX to enter and extract information into and from an LDAP directory service. OS/390 AET contains the LDAP V3 client function and a sample how-to-use.



ServerPac Release 6 Installation Enhancements

ServerPac continues to be enhanced to improve the installation of OS/390. A new function, Data Set Merge, enables customers to combine similar data sets (all panel libraries, for example) using the Installation Dialogs. The merged data sets can be saved and used by future ServerPac installations. Two new Installation Dialog commands: MERGE and UNMERGE, support this function.

ServerPac further streamlines installation by reducing the number of tasks needed to establish OS/390 UNIX. OS/390 UNIX elements and features are now delivered in a single file system. A customer can also use the Installation Dialogs to tailor jobs that install OS/390 UNIX and to set up its parmlib member.

Other Installation Enhancements: UNIX installation is further facilitated by a new CLIST provided to make it easier to set up OS/390 UNIX security administration.

The Planning and Migration Assistant for OS/390 provides reports that use IBM-supplied data, the customer's SMP/E CSI data set, and a CustomPac inventory file. These reports help the customer maintain, plan for, and order new releases of OS/390 and other products. The Planning and Migration Assistant for OS/390 will be available third quarter 1998 in SMP/E PTFs.

  • OS/390 Releases 3 and 4: UR50126 and UR50128
  • OS/390 Releases 5 and 6: UR50127
The S/390 Software Information Base, which contains IBM-supplied data used by the Planning and Migration Assistant, is also available in PTFs and on the Web at URL: An interactive version of OS/390 Planning for Installation guides customers through installation planning tasks based on their choice of installation method and migration path. It is available at the OS/390 Installation Web site URL: RMF Installation: The installation process for RMF has been changed with OS/390 Release 6. For details, refer to the installation instruction in the OS/390 program directory.



Integration Testing

To help further reduce migration time, the OS/390 product is system integration tested using a production-like environment. This environment includes subsystems, such as CICS, IMS, and DB2. This additional testing supplements existing functional test with a focus on tasks performed by customers in the production environment, thus helping establishments move more quickly to new function. System integration testing is provided for all OS/390 releases.

An Integration Test Report is available at URL:



Euro Sign Support

Euro Sign support will be available by December 1998 via an APAR. This support will be provided for MVS/ESA (TM) SP (TM) 5.2 and 5.2.2 and all OS/390 releases.

Information on APARs that must be applied to support the Euro Sign can be found in the following PSP Buckets. For OS/390 support, the PSP Bucket is EURO390. For VM support the PSP Bucket is EUROVM. For VSE support, the PSP Bucket is EUROVSE.



Year 2000

When used in accordance with its associated documentation, OS/390 is capable of correctly processing, providing, and receiving date data within and between the twentieth and twenty-first centuries, provided all other products (for example, software, hardware, and firmware) used with the product properly exchange accurate date data with it.

S/390 Year 2000 Initiative: The Year 2000 presents many challenges and customers may be faced with different approaches and decisions in order to complete their Year 2000 project. Tools are an essential part of helping customers meet that challenge and, while there are many tools available, most are designed to work on source code. In July 1998, IBM announced Runtime Analyzer for OS/390 and MVS. Refer to Software Announcement 298-269 dated July 28, 1998. The Runtime Analyzer is an execution time-based software audit tool that helps identify Year 2000 date exposures in OS/390 and MVS applications. The Runtime Analyzer:

  • Is designed to work on load modules. It can be used with or without source code.

  • Provides an efficient runtime analysis and remediation environment, enabling user-written filter and postprocessing programs.

  • Handles online and batch applications, to cover many different types of applications an installation may have.

  • It can run on any existing S/390 Year 2000 ready processor.

  • Supports Batch, Started Tasks (STCs), CICS, and IMS applications.
In addition, an optional hardware assist is available on the 9672 Generation 4 and Generation 5 servers which can enhance the ability to address Year 2000 date problems by avoiding the overhead of handling program interruptions for instructions that require fixing.

The Runtime Analyzer will be included in ServerPac at the planned ServerPac availability date.



UNIX 98 Branding

OS/390 has already begun to deliver certain key functions meeting immediate customer needs that are associated with UNIX 98 branding. Additional UNIX 98 functions which deliver customer and application vendor value are planned for roll out over multiple future OS/390 releases.



Product Positioning

Customer acceptance of OS/390 continues to far exceed product forecasts and reflects IBM's on-going commitment and increased investment in delivering new and valuable function in response to customer enterprise computing wants and needs. Each release provides significant new technology enhancements and function.

OS/390 Version 2 Release 6 includes WebSphere Application Server for OS/390 (previously delivered as Domino Go Webserver 5.0), performance improvements for OS/390 UNIX, and significant enhancements to the CS OS/390. There is new function for the Network File System, enhanced DCE, LDAP, and Distributed File Service (DFS), expanded manageability with RMF and HCM, reduced complexity and expanded logger support for Parallel Sysplex technology, improved management of discretionary workloads, and Fast Ethernet high speed connectivity support.



Documentation Information -- What's New for OS/390 Version 2

Release 6

Check out IBM's enhanced Year 2000 Web site at URL:

What can customers do if they are still not sure they know enough about the Year 2000 challenge? At this site, they find a comprehensive collection of information about the Year 2000 transition, including pointers to more documentation, products, services, and a link to a task map that describes the functional changes made to OS/390 elements to make them Year 2000 ready.

More Web site enhancements:

The OS/390 Web site at URL:

has also been improved. Web readers are able to find interesting new information here about downloads, such as Java for OS/390, UNIX tools and toys, and vendor information, including a handy list of software service providers with their products and compatibility charts with OS/390.

Also at this Site -- Easier Access to Service Updates to OS/390 Information: To ensure that updates to information based on PTF or documentation APARs are easily available on a timely basis, customers are able to access recent service and maintenance information for the elements and features of OS/390 at this site. The information is refreshed on a weekly basis.

And ... PDF Files!: For Release 6 of OS/390, IBM provides the OS/390 books as Portable Document Format (PDF) files from the OS/390 Internet Library selection at the OS/390 Web site.

PDF files are highly compressed files that can be read on almost any workstation platform and are produced as high-quality printed documents. Each OS/390 book is one PDF file.

To view, navigate through, and print PDF files, the Adobe Acrobat Reader, which is available from the OS/390 Internet Library at no charge and many other Internet locations, is required. The latest levels of many browsers can be set up to automatically start the Acrobat Reader software so that one can read and print PDF files from the Internet without having to store them on their system.

PDF Files Are Also Available on a New CD-ROM Collection: A new basic CD-ROM collection, shipped with OS/390 Version 2 Release 6, contains the unlicensed books for the OS/390 base and optional features in PDF format. This new OS/390 V2R6.0 PDF Library Collection (SK2T-6718) can be used to easily print high-quality hardcopy books.

The hardcopy books, printed from PDF files, look exactly the same as if they were ordered directly from IBM. This includes graphics, and the printing of all page numbers in, for example, the table of contents, on the pages themselves, and the index. Instead of printing entire books, the customer can decide to preview a book and print only selected pages.

And at the installation page at our OS/390 Web site, check out IBM's interactive planning tool for installation! It is available at URL:

This helpful interactive tool guides the reader through installation planning tasks based on their choice of installation method and migration path.

Introducing the New Softcopy Receiver Tool (SCRT) with Library Management: With Release 6 of OS/390, IBM introduces the Softcopy Librarian. It uploads and manages softcopy books on OS/390 hosts. The Softcopy Librarian incorporates the Softcopy Receiver Tool (SCRT) for Windows 95 and NT users. The new Softcopy Librarian, with SCRT R3.0, is being made available at no charge on IBM Online Library collections and on other IBM product CDs.

The Softcopy Librarian will begin shipping on IBM collections beginning in December 1998. Individual collections will indicate when they are fully-enabled for the new Softcopy Librarian.

With the new Softcopy Librarian, customers now have these added capabilities:

  • Supported file types -- They can upload current BookManager (R) book files.

  • Tracking of new and changed files -- Customers can define a repository for softcopy books on one or more OS/390 systems and let the Softcopy Librarian help them to manage what is sent to them.

    The Softcopy Librarian keeps a catalog of all the bookshelves and book files that are sent to the OS/390 host or server from any level of a CD. When a new level of the CD arrives, the SCRT compares its contents with the catalog and shows what is new and what is changed since the last level received. Customers now have a way to see, at a glance, what is currently on the host. Customers can save time and DASD space, because they upload only what they need and can easily delete the bookshelves and books that are no longer needed. When customers choose a bookshelf to upload, only the new and changed books in the bookshelf are uploaded.

    Customers no longer need to keep track of files by hand or with tools that they created that might not always produce consistent results. Customers no longer need to upload everything just to be sure that they have not missed something. And, they no longer need to upload duplicate books just because they are duplicated on the CDs.

    While the Softcopy Librarian prefers to work with bookshelves, customers can upload individual books. However, they are not able to delete individual books from their host if they are still in use by any bookshelf.

  • Support for both hierarchical files and sequential data sets -- The Softcopy Librarian can support repositories in hierarchical files systems or sequential data sets. This means that customers can use both BookManager BookServer or BookManager READ to access the books and bookshelves on the OS/390 host or server.

  • Managing one's own and other manufacturers' book files -- The new Softcopy Librarian enables customers to track shelves of BookManager books that they create or that they might receive with products from companies other than IBM.

  • Using Windows 95 and NT workstations -- The new Softcopy Librarian uses SCRT R3.0 and both are installed and run on Windows 95 and NT workstations.

    OS/2 users still have the current OS/2 SCRT R2.3 available, but it does not include the Softcopy Librarian.

Note that the Softcopy Librarian does not support uploading books from tape. Also, beginning with Release 6, the OS/390 product library on tape will not be refreshed three months after Georgia.

Printing softcopy books: As customers may know, the Softcopy Print element of OS/390 can be used to print softcopy books. For the details, see OS/390 Printing Softcopy BOOKs (S544-5354). To show the look and feel of a book printed with Softcopy Print, the copies of OS/390 Printing Softcopy BOOKs that IBM distributes are actually printed with the OS/390 Softcopy Print function.

Enabling OS/390 Optional Priced Features

OS/390 optional priced features use an OS/390 product registration service, together with product policy statements, to determine whether or not the OS/390 priced feature has been ordered and should run.

Those OS/390 optional priced features, that are ordered concurrently with OS/390, will be shipped by IBM together with policy statements in PARMLIB which enable the ordered priced features. OS/390 priced features, which have not been ordered, will also be shipped with OS/390 but with policy statements which disable the unordered features. If the customer subsequently enables any of the optional priced features, those features also become subject to the payment terms of the customer's existing OS/390 license as described in OS/390 Program Licensed Specifications (GC28-1728). Customers must notify IBM when they enable an optional feature that was shipped disabled from IBM. A detailed description of the enablement support for OS/390 features is available in OS/390 Planning for Installation (GC28-1726). This publication is available at the OS/390 Installation URL:

The OS/390 priced features which support this enablement capability in OS/390 Version 2 Release 6 are:
  • BookManager BUILD
  • BDT File to File
  • BDT SNA NJE
  • C/C++ (with Debug Tool)(3)
  • C/C++ (without Debug Tool)(3)

Program Services

Central service for suspected defects in OS/390 code is provided by the IBM Support Center within the customer's geography. Central service, including the IBM Support Center, for DSLO licenses is provided through the customer location designated for the basic license. On-site (local) support, although available, is provided as part of IBM's portfolio of fee-based services.



Service Policy

It is IBM's current intention to consider each release of OS/390 as current for three years following its general availability date, and to provide maintenance during that period.

Recognizing the workload customers have ahead of them for year 2000, OS/390 Version 1 Release 1, 2, and 3, and Version 2 Release 4 will deviate from this service policy. These OS/390 releases will be considered as current until at least January 31, 2001, with IBM providing maintenance during this period.

PTF distributions, including Recommended Service Upgrades (RSUs), will continue to be available monthly through the period the release is current. RSU integration testing for a release will be performed for five quarters after the General Availability date for that release.

Service on the last release of a version might be extended beyond the intended three year-period. In all cases, the current practice of providing at least twelve months written notice prior to the withdrawal of service for a version or release, will continue for OS/390.

All statements regarding IBM's future direction and intent are subject to change or withdrawal without notice and represent goals and objectives only.



Enhanced HOLDDATA is Now Available Including Year 2000 Information

Enhanced HOLDDATA, previously announced in OS/390 Version 2 Release 4, is now available and replaces the HOLDDATA that is delivered on ESOs and Corrective Service Orders. (Refer to Software Announcement 297-355 dated September 9, 1997, to review the HOLDDATA announcement in Release 4.) In addition, Enhanced HOLDDATA includes information to ease identification of missing Year 2000 service. IBM's direction is to provide Enhanced HOLDDATA on other IBM deliverables and IBMLink (TM) by December 1998.

Enhanced HOLLDATA improves the content, timeliness, and consistency of HOLDDATA. These improvements make it easier to identify and analyze missing critical service on any level of an OS/390 or MVS system. ++HOLDs are now created for HIPER (High Impact and Pervasive) and Year 2000 APARs in addition to PE (PTF in Error) APARs. Additional information is provided that includes the fixing PTF number, when available, and any HIPER reason flags.

Year 2000 APARs have a reason flag of YR2000.

Enhanced HOLDDATA is cumulative and complete. This allows Enhanced HOLDDATA to be a single source of HOLDDATA to serve multiple systems. There is no longer any need to collect and compile ERROR HOLDDATA from multiple sources. The content covers the entire OS/390 and MVS platform of IBM's SMP/E-managed products with one consistent source of HOLDDATA.

Note: Coverage of the entire platform with a single HOLDDATA source does not negatively affect processing HOLDDATA since SMP/E ignores data for products that not listed in the SMP/E environment.

Timeliness of Enhanced HOLDDATA is improved by providing daily updates available via the Internet at:

The files on the Internet are the same files that are delivered on orders built that day. HOLDDATA can be kept current by downloading and receiving the most recent file. Subsequent updates of the Web data can be downloaded and received on top of existing HOLDDATA without concern about regression of HOLDDATA, provided the time span of the latest Enhanced HOLDDATA overlaps any previously RECEIVEed HOLDDATA. Automation of data retrieval is possible through the use of Batch FTP and job scheduling.

The above referenced URL also contains additional information about Enhanced HOLDDATA.

S/390 Server Consolidation Initiative Release 7 Items

  • Enterprise and Systems Management
    • Tivoli Management Agent

      The Tivoli Management Agent will be available as part of the OS/390 base, thus integrating the support that makes OS/390 Tivoli Ready. Customers will be able to manage OS/390 using Tivoli's management software, and thus, over time, can help reduce their total management cost by managing their entire IT environment in a consistent way across all platforms and business applications. The Tivoli Management Server and Gateway for OS/390 are planned to become available during 1999. This will enable Tivoli applications to manage the enterprise from OS/390.

    • Withdrawal of SystemView OS/390 Base Element

      With the integration of Tivoli into OS/390, the SystemView element will be removed from OS/390 beginning with Release 7.

    • RMF

      System Enclave Support: The enclave support in Monitor III will be enhanced to assist customers in managing business units of work in their Parallel Sysplex environment. Many new types of applications (for example, Distributed Data Facility, SAP R/3) create enclave transactions that execute in several address spaces but need to be managed as their own single business units of work. Therefore, a report showing resource consumption and delays by enclave will significantly enhance the customer's ability to improve performance management for these new applications.

      Support for OS/390 UNIX System Services: Two new reports, Monitor II and Postprocessor, will provide performance information on the Hierarchical File System (HFS). These reports will enable customers to tune their system to better use HFS resources. Based on the storage information and utilization statistics in the new reports, customers will be able to optimally size the HFS buffers.

    • HCM

      HCM Enablement of Tivoli Inventory for S/390 Data: Tivoli's inventory management application, Tivoli Inventory, is a computer hardware and software inventory gathering system designed to help system administrators and accounting personnel who manage the complexity of a distributed client/server enterprise.

      HCM will be extended to optionally interface with Tivoli Inventory 3.2. This support will make OS/390 hardware configuration data derived in HCM available for placement in the inventory repository. This HCM support consists of extending and converting HCM's exported configuration data to a MIF file that can be processed by Tivoli Inventory.

      HCM as a 32-bit Windows Application: Starting with this release, HCM will be changed to run as a native Windows 32 bit application only on Windows 95/98 and Windows NT.

      Note: HCM will no longer run on Windows 3.x or WIN-OS/2 (R).

      HCM Visualization of ESCON Director Configurations: This feature will use ESCON Director Configuration information to provide better visual feedback concerning which devices are accessible and which devices are not accessible when certain ESCON director configurations and crossbar switch configurations are used.

      HCM FICON Migration Function: The following functions will assist customers for their FICON migration:

      • Convert ESCON director port card to FICON port card.

      • Move port connections from one ESCON port to another ESCON port.

      • Aggregate CHPIDs on an ESCON director. On one ESCON director, this function will aggregate all I/O equipment connected via several source channels to one target channel.
      The Move port connections and Aggregate CHPIDs functions can also be used for configuration changes that do not involve FICON Channel. In particular, the ability to move port connections will be useful for the installation of new ESCON directors.
  • Security and Directory

    LDAP Access to RACF Data: RACF data presents a large set of user, group, and profile information that is useful to applications in other environments or on other systems. This item will make RACF information that is accessible through SAF interfaces, available via an OS/390 LDAP server to programs on and off the OS/390 platform.

    LDAP Multi-Server Enhancement: This item enhances the LDAP Multi-Server capability that is already available with OS/390 Version 2 Release 6. It will support multiple LDAP servers on multiple OS/390 systems in a Parallel Sysplex environment and will exploit the OS/390 Workload Manager to achieve a balanced utilization of LDAP servers accessing the same directory.

    LDAP Java (JNDI) Support: This item will provide the industry-standard Java Naming and Directory Interface (JNDI) for the OS/390 LDAP client so that developers can build portable, Java directory-enabled applications which can run on OS/390. It will provide access for Java applications on OS/390 to LDAP information stored on OS/390 as well as other LDAP-supported platforms.

  • Workload Consolidation

    OS/390 Distributed Computing Environment (DCE): DCE Security function will be elevated to Open Group DCE 1.2.2 level so that interoperability can be maintained between DCE applications on all platforms.

    OS/390 Distributed File Service (DFS): IBM will enhance the OS/390 DFS to complete the OS/390 implementation of the OSF 1.2.2 DCE DFS function. DFS Server Multi-home Support will be provided to improve DFS server availability on an OS/390 host that is connected through multiple interfaces to multiple networks. Protected DCE RPC support will be provided to allow for more secure network access to file data by enabling an administrator to specify a range of DCE authentication levels that can be used in DFS client-server communications.

    DFS will continue to be enhanced to be functionally compatible and equivalent with DCE DFS implementations on other systems and to expand the support for workstation access to OS/390 file data. This will include OS/390 DFS server support for file level translation controlled at the file extension (file type) for HFS files; large DCE LFS aggregates with a size value greater than 32-bits; and the capability to create a DFS mount point in HFS. Also, DFS will continue to implement performance and RAS enhancements based on customer experiences involving more than 10,000 users in a university environment.



S/390 e-business Initiative Release 7 Items

IBM plans to deliver the following functions into the level of the WebSphere Application Server that will be integrated into OS/390 Version 2 Release 7. These functions will be based on the HTTP engine functions offered by Lotus Domino Go Webserver:

Performance Enhancements: Enhancements to the WebSphere Application Server and the eNetwork Communications Server will offer up to two times improvement in the number of connections per second as measured by Webstones.

Support for a Webserver Adapter: This adapter enables a customer using Domino for S/390 to optionally select OS/390's WebSphere Application Server as an alternative HTTP engine instead of what is shipped with Domino for S/390. This support enables Webserver authentication to be under the control of Domino Notes (TM).

eNetwork Communication Server for OS/390 (CS OS/390) - An Enterprise Class Solution for e-business Networking: IBM will continue to deliver on its commitment to provide world-class TCP/IP solutions for e-business networks while increasing the integration of SNA/APPN and TCP/IP networking services. Release 7 will include the following enhancements:

  • Further improvements to TCP/IP Parallel Sysplex support to increase usability, availability and performance

    Parallel Sysplex Sockets will help reduce overhead and improve performance. Socket applications will learn when a vendor application is in the same MVS image or Parallel Sysplex cluster. This will enable applications to:

    • Share information so that each application need not incur overhead to generate it when in the Parallel Sysplex cluster

    • Achieve secure communications without the overhead of encryption

      System-wide benefits include: reduced CPU cycles, improved overall performance, and reduced application overhead.

    XCF Dynamics will offer nondisruptive horizontal growth for TCP/IP in a Parallel Sysplex environment. XCF Dynamics will make it possible to add new TCP/IP images without requiring coordinated definitions for existing Parallel Sysplex members. Only a single definition will be needed for each new TCP/IP image. This will make it easier to nondisruptively scale up to handle increased workloads without impacting the existing systems and their users.

    System Symbolics for TCP/IP will reduce definition workload. This usability enhancement will reduce the number of definitions required for a TCP/IP stack in a Parallel Sysplex cluster through the use of system symbolics in the PROFILE.TCPIP and TCP.DATA configuration files.

  • Fast Response Cache Accelerator will extend S/390's lead as enterprise server of choice.

    Fast Response Cache Accelerator is expected to provide two times performance improvement. Customer requirements for even higher-speed Web performance will be addressed by this IBM-unique new technology. It will cache Web pages within the TCP/IP services stack enabling significantly faster processing of requests for Web pages.

  • Service Policy Agent will offer Priority Networking for TCP/IP. The Service Policy Agent will enable a network administrator to control the performance characteristics of IP data packets as they travel the network by enabling the setting of the Type-Of-Service byte. This byte will be utilized by CS OS/390 and by IP routers for queueing and discarding algorithms to help ensure proper prioritization of IP data traffic. This enhancement will also enable differentiation of services based on administrative controls and service requirements. For example, differentiation can be made based upon:
    • Service Level Agreements
    • Classes of users
    • Application needs (for example, high bandwidth)
    • Mission-critical applications
    • Time of day
  • Internet Security will be further improved with Triple DES, latest RFCs, and more

    Firewall Technologies will be enhanced. Performance and RAS improvements will help minimize the overhead of critical network security technologies while helping to maximizing their RAS so that they are always on guard. Virtual Private Network (VPN) support will be upgraded to the latest draft level of IPSec for secure S/390 connectivity to servers that may have also upgraded to the latest draft level. This VPN enhancement will include the addition of HMAC-MD5 and HMAC-SHA authentication algorithms as well as replay protection. Triple DES support will be added and will use S/390's triple DES encryption hardware if present.

    Simple Network Management Protocol Version 3 (SNMPv3): This CS OS/390 Release 7 enhancement will deliver compliance and currency with Internet Engineering Task Force (IETF) standards and RFCs along with interoperability with other products desiring secure SNMP exchanges. These new capabilities will include message security, user-based security, and view-based access control.

  • Enhanced Addressing for TN3270 Server

    Enhanced addressing will be used by the CS OS/390 TN3270 Server in an APPN/HPR environment to significantly reduce the consumption of network resources and at the same time increase server capacity. Other session managers, such as TSO/VTAM, will also benefit from this improvement.



S/390 Applications Initiative Release 7 Items

  • Language Environment for OS/390 will have the following enhancements delivered in Release 7:

    CEEROPT: By setting region-wide run-time options, customers will receive benefit from a stand-alone run-time options module that can be used to provide region-wide installation defaults in CICS and IMS environments. This will eliminate the need for customers to reinstall the installation default options on every release and maintenance fix for the Language Environment.

    RAS: Customers, who are used to looking at system dumps, will now be able to request the Language Environment to take a systems-only dump without a Language Environment formatted CEEDUMP.

    Customers will now be able to obtain a system dump of first failure data capture prior to the Language Environment's error recovery process.

    Performance: Customers will benefit from a reduction in the EXEC CICS LINK path length. Customers should also see Language Environment using less below-the-line storage. And, the current default storage settings will be modified under CICS resulting in a reduction in CPU time.

    Version Alignment: The Language Environment for OS/390 version and release numbers will be aligned to correspond with the version and release numbers of OS/390.

  • OS/390 UNIX System Services (OS/390 UNIX)

    Performance: Customers will see the following performance improvements in Release 7 for OS/390 UNIX System Services:

    Application support will be more seamless to enable the WebSphere Application Server to run CGI programs in a faster manner. Customers will see faster access to sockets through Async I/O Real Time Signal Extensions. A dynamic reduction in the path length of file name lookups should be achieved through selective bypass of SAF calls on pathname lookups.

    RAS: Multiple RAS improvements will be available. Full text will provide Kernel error codes. IPCS support will be improved for UNIX environments. The ability to diagnose problems in Lotus, Web, and DCE will be improved with the addition of a modified ps command that will enable the caller to display information for the threads in a multi-threaded server.

    User Dump Support: New support will be provided for obtaining user dumps and system dumps in all environments.

S/390 Business Intelligence Initiative Release 7 Items

Many customers are investing substantially in the design and implementation of large-scale Business Intelligence (BI) systems. Business Intelligence solutions include Warehousing, Data Mining, and Decision Support Systems. These investments include BI databases that are growing to hundreds of gigabytes, and in some cases, to multiple terabytes.

As these solutions get larger, they are also becoming more mission-critical and can require the inherent strengths of S/390 hardware and software.

IBM's S/390 Division has invested significant resources in the BI initiative to provide S/390 system solutions that support the hub data warehouses and decision support servers large customers require to complement their current and future business-critical applications.

IBM has dedicated significant technical and service resources to scope, design, and implement practical S/390 BI solutions that include both IBM and business partner products and services with the principal focus being on IT consultants, data warehouse designers, system integrators, and business and IT executives. S/390 alliances are being strengthened with major, recognized BI leaders, BI software and services providers required to implement successful customer data warehouses.

The S/390 BI product development strategy is to evolve S/390 Parallel Sysplex-capable hardware and OS/390 to help meet the needs of increasingly diverse BI applications running on the S/390 platform. Investment in DB2 and in Data Mining technology is also included. Existing OLTP and query applications, new query and ported applications from proprietary UNIX and Windows NT environments place increased demands on the need for secure, robust, large-scale S/390 Enterprise Servers with goal-focused OS/390 systems management.

Central to the S/390 BI strategy is S/390 Parallel Sysplex technology, OS/390 with Workload Manager, and DB2 for OS/390 to support parallel queries and mixed query workloads in a data sharing environment. Additionally, IBM is providing services that enable parallel UNIX applications to move to the S/390 platform easily. The UNIX System Services Parallel Environment is designed for this purpose. These services enable user level parallel processing in application programs through the implementation of the Message Passing Interface (MPI) standard. This enables the creation, run-time management, and inter-communication of distributed parallel processes working cooperatively as a single application. The following enhancements are planned for OS/390 Version 2 Release 7:

OS/390 UNIX Parallel Environment: Parallel Environment will be enhanced to support the MPI 1.2 specification for C and C++ applications. Further enhancements include:

  • POSIX file support for essential parallel I/O interfaces will be introduced with the MPI 2.0 specification

  • Support for the Multiple Program Multiple Data (MPMD) parallel application model

  • Support for multi-threaded user applications

  • New online documentation using man pages

  • Additional utilities to make setting up, running, and testing Parallel Environment applications easier (for example, multiple copy utilities)

  • Usability improvements to the Parallel Operating Environment component of Parallel Environment (for example, Validate Log-Space, enhanced informational messages, improved parsing of command line options, additional messages).

S/390 Technology Leadership Initiative Release 7 Items

  • WLM Support for MQSeries (R) Workflow for OS/390

    MQ (TM) Access Hub will use existing Workload Manager services and new support in the WLM administrative application to enable classification and management of MQSeries-driven work. Typically, work is classified and managed when a work manager for an application receives the work request. For instance, work is classified and managed through WLM in a distributed DB2 environment when the DDF address space receives the request. Due to the asynchronous nature of messaging and queuing, there can be delays from the time a message arrives on a queue until the time it is received for processing by the target work environment. By classifying and managing the work as it arrives on the MQSeries queue, this delay can be accounted for by the OS/390 Workload Manager so that it can better manage the business goals of the work.

    The initial use of WLM functions will be for requests originating from the MQSeries Workflow for OS/390 product. Acting in a server address space capacity, the MQSeries Workflow engine will be driven by MQSeries messages that arrive on a specified queue. MQSeries will classify the message and inform OS/390 Workload Manager of its arrival so that the work can be started and managed to meet the work's business goals.

  • S/390 Fiber Channel (FICON)

    In May 1998, a new high-performance I/O channel was announced (refer to Hardware Announcement 198-115 dated May 7, 1998) as part of the new processor. Each FICON channel is capable of supporting more that 4,000 I/O operations per second which enables each channel to support the same capacity as up to eight ESCON channels. FICON is a fully compatible evolution of parallel and ESCON channels and provides both improved I/O rates as well as more bandwidth. New applications, such as network computing, decision making, multimedia, and object-oriented technology can take advantage of FICON high performance.

    Software support will be in the then current release of OS/390 and in SPEs back to OS/390 Version 1 Release 3. Most of the support consists of changing OS/390 to take advantage of the improved performance of FICON channels, in providing constraint relief, and in reducing the complexity of managing a large number of channels. In the then current OS/390 release, HCD/HCM will provide a new migration tool to help customers define the aggregation of ESCON channels to FICON channels.

  • DFSMS/MVS Version 1 Release 5
    • DFSMS/MVS Version 1 Release 5 will deliver a major restructuring of HFS to improve performance. Reduced path lengths, removal of serialization bottlenecks, and improved buffering capabilities will enable an order of magnitude in throughput for files less than 512K bytes in size. More detailed performance information will be available at Release 7 general availability.

    • HFS will support multi-volume datasets, so that customers will be able to eliminate growth restrictions on their applications, such as Lotus Domino.

    • Customers will have a new HFS interface that will enable them to perform additional functions, such as retrieving statistics and dynamically extending HFS data sets.

    • HFS will preserve the integrity of mounts in a shared environment.
    DFSMS/MVS Version 1 Release 5 will improve the performance of shared catalogs in a Parallel Sysplex environment. DFSMShsm users will be able to take advantage of the new higher availability application support, inherent in Parallel Sysplex support, by using secondary host promotion. If a host or address space, that is running DFSMShsm primary function fails, any secondary host will be able to be promoted to take over these functions using standard XCF/Parallel Sysplex function. If a host or address space that is running Secondary Space Management (SSM) fails, another host in the Parallel Sysplex cluster will be able to be promoted to take over this responsibility. Also, DFSMShsm performance of incremental backup has been improved by overlapping input/output operations with catalog and HSM control data set update operations. DFSMS/MVS Version 1 Release 5 will provide the ability to maintain multiple HSMplexes within a single Geographically Dispersed Parallel Sysplex cluster. Each HSMsubplex will have its own set of control data sets and manage its own set of user catalogs and data sets. This will ease requirements for merging DFSMShsm Control Data Sets as customers merge existing complexes into Parallel Sysplex clusters. This enables easier management of emerging Geographically Dispersed Parallel Sysplex clusters. As customers grow their complexes and merge them into Parallel Sysplex clusters, IBM has concluded that the current maximum size of the DFSMShsm control datasets is an inhibitor to growth and Parallel Sysplex technology implementation. To that end, in DFSMS/MVS Version 1 Release 5, the DFSMShsm control datasets will take full advantage of VSAM extended addressing that was introduced in DFSMS/MVS 1.3. Growth in a customer's installation will no longer be curtailed by the size of DFSMShsm's control datasets.

    DFSMS/MVS OAM will exploit Parallel Sysplex technology architecture to enhance availability and enable instances of OAM that belong to an XCF group and are connected to DB2 subsystems. OAM will use DB2 data sharing to have full access to OAM objects, thereby removing the old limitation that only the system that owns the object can access it. OAM will now support more than 100 storage groups in a configuration. Customers will also be able to specify their own high-level qualifier for object storage groups and their associated DB2 tables.

    DFSMS/MVS Version 1 Release 5 will provide a series of new functions to DFSMSrmm. An API to enable READ/WRITE access to the DFSMSrmm Control Data Set will be available. This API will enable customers to write programs to query and update fields in the CDS. In addition, this API could be the basis of interaction between DFSMSrmm and other vendor programs for tape dataset stacking and production scheduling and control. This API will be available on DFSMS/MVS 1.3 and 1.4 as APAR OW30369. Separate retention and vaulting policies will be available for DFSMSrmm that provide more flexibility for customers as they define policies which simplify conversion from other products to the OS/390 platform. In addition, DFSMSrmm will also provide special handling instructions through a DD statement to improve communications with operations personnel and to produce output operations, such as printing labels, assigning volumes to loan or storage locations, or identifying future processing or removal from site. DFSMSrmm will extend support for sharing a single control data set across systems that do not share catalogs by tracking catalog status and enabling some functions to run on each system.

    Naviquest, which enables customers to perform regression testing on their ACS routines, change SMS constructs in batch, and invoke batch reports through ISMF, has been further enhanced to enable define, alter, and display of Data Class, Storage Class, Base configuration and aggregate group. This will enhance storage administrator productivity.

    DFSMS/MVS will provide a methodology that enables an alias in a shared master catalog to be interpreted differently on each system in the Parallel Sysplex environment based upon the parameter specifications supplied on each system. This new methodology can make a shared master catalog environment easier to use.

    For growth enablement, DFSMS/MVS will enable subsystems, such as CICS and IMS, to exceed the past limitation of 8,191 open datasets.

    To enhance the usability of the DFSMS/MVS product line, functions, such as extended addressing, partial release, candidate volume space amount, and system managed buffering were made available to users of extended format VSAM key sequenced datasets in previous releases of DFSMS. DFSMS/MVS Version 1 Release 5 will provide support for extended format to VSAM ESDS, RRDS, VRRDS, and LDS along with the aforementioned extended format capabilities.

    ANSI Version 4 tape label support will be added. This new support will enable data interchange between OS/390, MVS, and non-S/390 systems. Basic Tape Library Support (BTLS) will continue to be supported in this release.



S/390 SERVER CONSOLIDATION INITIATIVE UPDATE

For some businesses, the proliferation of servers in networked environments has led to high management costs and server management nightmares. Many IT managers are rethinking their IT infrastructures and are considering centralizing or consolidating distributed servers. A recent survey (InformationWeek, September 1997) of 250 IS executives revealed that 20% of the respondents had already begun centralizing distributed systems, and that 60% were planning to centralize their distributed systems. The primary business motives that drive server consolidation are the reduction of total cost of ownership and enhanced functionality. Today, customers are motivated to reduce systems management complexity, increase physical and data security, reduce administrative staff, optimize server capacity, and improve reliability and availability. Customers are now motivated by faster response times and increased access to data. This may include enhanced intra- and extra-organizational data sharing, standardization of applications/services for multiple business units, and upgrade of existing enterprise systems, such as BaanERP or data warehouse solutions. In addition, customers require the ability to scale processing and storage capacity without adding physical devices, as well as the flexibility to partition and allocate resources as needed.

Server Consolidation means different things to different people. Five major categories of consolidation follow:

  • Centralization -- relocating existing servers to one or fewer IT sites

  • Physical Consolidation -- reducing the number of servers by replacing (many) small servers with fewer large servers. Physical consolidation may be implemented on a site, department or enterprise basis.

  • Data Integration -- combining data from different sources (same or disparate types) into a single repository and format (for example, moving data from multiple, discrete sources such as departmental servers to create a data warehouse on an SP or S/390)

  • Data and Application Consolidation -- Migrating an application or data to a new platform in order to co-locate application and data

  • Mixed Application Workload Consolidation -- running multiple types of application workload types within a single server/system
S/390 Server Consolidation provides enablement in all categories with unique strengths and capabilities to address the complexity of consolidating and integrating data, application, and mixed workload consolidations. With OS/390, the S/390 flagship enterprise operating system and enabling technology for effective server consolidation, customers can:
  1. Consolidate servers through rehosting application and data workloads

  2. Improve systems management and security through centralized administration, operations, availability, and security management

  3. Integrate core applications with new applications through enterprise integration
Each of these areas can help leverage the scalability, reliability, security, and availability of S/390 -- helping to reduce total cost of ownership, increase systems management efficiency and enhance data integrity.

Note: Centralization and Physical Consolidations are handled by IBM Global Services offerings.

Data Consolidation: Customers continue to benefit from OS/390 LAN Resource Extension and Services (LANRES), LAN Server, Network File System (NFS) and Distributed File Service (DFS) as base components of OS/390 that permit centralization of LAN data to S/390. These four solutions, along with continued and updated releases of other products available from third parties, such as SAMBA for OS/390, can allow the customer to centralize file data (from Novell Network, Windows NT, OS/2 and UNIX) on S/390 for centralized data management, security and disaster recovery while helping to reduce the number of servers and support requirements.

OS/390 continues to expand on the customer value it delivers with forthcoming deliveries of Novell Directory Services (NDS) and Novell Network File and Print Services on OS/390. Using NDS on OS/390, customers can have a single point of administration for their directory and security services with access to both Novell and OS/390 resources. In addition, the Novell Network File and Print Services on OS/390 can enable customers to more efficiently consolidate the Novell servers in the enterprise, help reduce management costs and complexities, help reduce hardware, software, and maintenance costs, and gain control over the enterprise data.

With the continuation of greater integration of data along with consolidation of data from all sources on OS/390, customers can continue to gain further performance improvements and cost savings. This includes the ability to reduce servers and hardware connectivity components required while maintaining and often improving the overall performance.

Recently, Wachovia National Bank, a leading interstate financial services company serving the southeastern, national and international markets became concerned with the high cost of managing distributed file and print servers. The goal of the project was to provide equal function at drastically reduced cost by consolidating LAN data (file serving) and print serving onto their S/390. By deploying the OS/390 LANRes solution, Wachovia National Bank was able to meet their goals of:

  • Reduced hardware, software, and maintenance costs
  • Reduced LAN administration costs
  • Reduced number of user licenses
  • Improved user productivity
  • Reduction of outages
  • Simplified data access
UNIX Application Consolidation: IBM has created an open pipeline for UNIX applications running on the S/390 platform. OS/390 provides UNIX application programming interfaces (API), a UNIX shell environment and a hierarchical file system that are integrated into the OS/390 System Services. UNIX workloads, such as Lotus Notes (R), SAP R/3, Oracle and PeopleSoft, now can be run on OS/390 while others can be ported to OS/390, giving users the flexibility to choose the S/390 platform to run UNIX applications while consolidating workloads for control and cost benefits. Existing OS/390 applications continue to run unchanged while new ported UNIX applications run on the same OS/390 system.

Enterprise Systems Management and Security: Consultant studies continue to show that the strong Systems Management and Security capabilities of the platform are one of the reasons why customers chose to consolidate on S/390. At the same time, these studies show customers state that managing the distributed environment is one of the biggest challenges in 1998.

S/390 can help address both of these aspects. S/390 has a 25-year history in providing superior Systems Management solutions for the platform, through products offered by the S/390 Division, products offered by SSD (Storage Management) and more recently through Tivoli (Network and Systems Management) solutions. Complementary vendor products have also filled niches, or offered alternatives to IBM offerings in this arena, and validate both the strength and manageability of the S/390 platform.

The advent of multi-platform application implementations has increased the need for Systems Management applications to extend into the enterprise. Successful systems management is predicated on an end-to-end application management view, containment of systems management cost and leveraging existing management products.

Tivoli Management Software provides systems management applications based on a common management paradigm and architecture that focuses on managing the distributed, heterogeneous enterprise with a common administrator interface. Now, the capabilities of the Tivoli Management Software are being extended to OS/390, enabling OS/390 to be an integral part of Tivoli's management of the enterprise. OS/390 will be able to be the server for managing the total enterprise, and OS/390 can be managed as part of the enterprise. For example, Tivoli User Administration for OS/390 and Tivoli Security Management for OS/390 products will, over time, enable OS/390 to be the base for single action management of security throughout the enterprise, including the management of security on OS/390.

The Tivoli Management Architecture includes several pieces of support, two key pieces are the Tivoli Management Framework and Tivoli Management Applications. Both the framework and the applications have server and agent parts. The server part of the framework (Tivoli Management Server) provides various services and functions needed to support the application server functions of managing the distributed, heterogeneous enterprise. The agent part of the framework (Tivoli Management Agent) provides the services and functions needed to support application agents that generally accept instructions from the application server and implement those instructions on the system where the agent resides. An operating system may be enabled to host an application server (running on a framework server), or support an application agent (running on a framework agent), or both.

The support which enables OS/390 to be an integral part of Tivoli management of the enterprise will be delivered in stages. The first stage is in fourth quarter 1998 with the delivery of the support that enables OS/390 user and security management to be integrated with the management of users and security throughout the enterprise. This support includes the agents for the Tivoli Management Framework for OS/390, Tivoli User Administration for OS/390, and Tivoli Security Management for OS/390.

The second stage, planned for 1999, enables OS/390 to be the management platform for Tivoli management of the enterprise (including OS/390). This support is very important to many customers because of the security, availability, scalability, and workload management capabilities of OS/390. This support enables OS/390 to manage users and security, software distribution, and gather and report on other components of the computing infrastructure across the enterprise. The support that enables these capabilities are the servers for the Tivoli Management Framework for OS/390, Tivoli User Administration for OS/390, Tivoli Security Management for OS/390, Tivoli Software Distribution and Tivoli Inventory. In the future, additional Tivoli application servers and agents will support OS/390.

The Tivoli Management Framework will be available on OS/390 for no additional cost. The Tivoli Management Agent for OS/390 will be available in fourth quarter 1998 with support for OS/390 Release 3 and subsequent releases. The Tivoli Management Agent for OS/390 will become a base element of, integrated into, OS/390 Release 7. The Tivoli Management Server (and Gateway) will be made available in 1999 with support for OS/390 Release 3 and subsequent releases. The Tivoli Management Server (and Gateway) will become base elements of, integrated into, a subsequent OS/390 release. Tivoli management applications are individually selectable and priced program products.

OS/390 continues to deliver leading Systems Management and Security solutions. Existing OS/390 Systems Management applications will further integrate/inter-operate or merge with Tivoli applications to bring additional systems management applications with a common look and feel on the administrator's desktop. More and new Tivoli Management Environment (TM) framework-based applications will run on OS/390 and exploit the scalability and availability of the OS/390 platform. For security management, Tivoli's User Administration and Security Management products for OS/390, handle the frequent user and resource administrative tasks across multiple platforms with one administrative action. Additional application specific management modules based on Tivoli's open application management specification will provide the support to effectively manage business applications across the Enterprise.

The OS/390 security infrastructure will act as a local Certification Authority, creating a trusted root for digital certificates issued for use within the enterprise's intranet and extranet users. Users authenticated by cross-certified digital certificates, can freely access public data (for example, electronic storefront) without being defined on each S/390 system without loss of accountability, for browsing and consumer order entry. Improvements in S/390 cryptographic capabilities, and improved secure communication protocols suites can help further reduce the cost of conducting secure e-business transactions. The OS/390 LDAP directory server and Novell Directory Services (NDS) for OS/390 will closely cooperate with the OS/390 security repositories, exploited by OS/390 applications and, applications on other platforms to create an enterprise wide directory, locating users and resources within the enterprise. User Identity management between applications both deployed on OS/390 and other platforms will be centralized within the OS/390 Security Server improving the inter-operation between applications when deployed on S/390. These capabilities can continue to help reduce the cost of ownership, and provide technological excellence, creating additional value to our customers, that is realized through consolidating applications on S/390.

MQSeries Enterprise Integration for OS/390: IBM plans to deliver MQSeries-based middleware offerings on OS/390 for enterprise integration which strongly support customers in automating their business processes in new emerging technology areas, such as e-business. These offerings can exploit the unique server capabilities of OS/390 such as, high scalability and recoverability of whole processing steps. It will provide complete and once-only delivery of requests by using MQSeries as the communication vehicle.

The first delivery, MQIntegrator for OS/390, will help ensure that the automated processes can integrate applications from various platforms (all platforms supported by MQSeries) into one defined process. Data translation and format mapping tools will help the customer in exchanging data between applications as different in formats as Web-, IMS-, and CICS-based applications. Special formatters for S.W.I.F.T, SAP R/3, and PeopleSoft are also available. MQIntegrator for OS/390 will be available in the third quarter 1998.

The second delivery, MQSeries Workflow for OS/390, later in time will provide complete workflow functionality which not only allows to invoke transactions (including data exchange) in a simple parallel way but also allows to define any conditional sequential flow in which the transactions can be invoked based on defined conditions of data values. Applications and data from various platforms can be integrated into this flow of processing across the whole enterprise and participating communities. This workflow functionality allows not only for automated transaction processing but can also invoke human interaction according to business roles. High flexibility will be provided with a GUI editor for the definition of these processes. This process information will be stored in DB2 tables for later access at run time.

All the offerings will follow MQSeries Enterprise Integration Blueprint.

The MQIntegrator and the MQSeries Workflow will be available with SmoothStart Services to help customers with a quick and smooth start. Additional services offerings will help customers through the implementation of enterprise integration projects.

Compatibility

OS/390 Coexistence: Up through the announcement of OS/390 Version 2 Release 4, IBM allowed three consecutive releases of OS/390 to coexist in a multisystem complex or Parallel Sysplex environment. To better meet customer requirements as they plan and prepare for improved migration compatibility and Year 2000 activity, IBM has further invested in its industry-leading OS/390 Integration Testing and has extended the coexistence policy so that it supports four consecutive releases of OS/390 in a multisystem complex or Parallel Sysplex environment. This extension to the OS/390 coexistence policy includes all OS/390 Version 1 releases, all currently announced OS/390 Version 2 releases, and all future releases of OS/390. The period for OS/390 coexistence now extends from 18 months to a maximum of two years based on the current six month release cycle. The coexistence extension from three consecutive releases to four consecutive may be withdrawn at IBM's discretion at a later date. In all cases, the current practice of providing at least 12 months' written notice prior to withdrawal of support will continue.

This extension to the OS/390 coexistence policy also applies to the JES2 and JES3 elements of OS/390. That is, the JESes can coexist for four consecutive JES releases. In addition, since OS/390 allows the JES element to be staged, this has been taken into account in the JES coexistence policy. If a JES element provided in a particular release of OS/390 is functionally equivalent to its predecessor (that is, the JES FMID did not change), then from a coexistence standpoint this is considered the same JES release. As an example, the JES3 element delivered in OS/390 Release 2 has the same FMID as the Release 1 JES3 and is considered to be functionally equivalent. The JES3 FMID did change in OS/390 Releases 3, 4, 5, and 6. Based on this example, the Release 5 JES3 can coexist with the Release 1 JES3 and Release 2 JES3 since Release 2 JES3 is the same as Release 1 JES3, but Release 6 JES3 cannot coexist with JES3 Release 1 or JES3 Release 2 as this falls outside the four consecutive JES releases.

As a one-time special provision, IBM will support the coexistence of Release 6 JES3 with Release 1 JES3 and Release 2 JES3. A similar provision for OS/390 JES2 is not being provided, since OS/390 JES2 Releases 1, 2, 3, 4, 5, and 6 can coexist under the current four consecutive JES release coexistence policy. That is, Release 1 and Release 2 JES2 as well as Release 5 and Release 6 JES2 are considered functionally equivalent and the JES2 FMID did change in OS/390 Releases 3 and 4. This one-time provision for JES3 can be withdrawn at IBM's discretion at a later date. No further provisions or extensions for coexistence are planned for OS/390, JES3, or JES2. The OS/390 JES releases that can coexist as well as the releases of MVS/SP (TM) JES that can coexist with OS/390 JES are shown in the charts under OS/390 Coexistence with MVS.

OS/390 Coexistence with MVS: Currently, OS/390 and supported MVS releases can coexist in a multisystem complex or Parallel Sysplex environment. IBM plans to discontinue this support effective with the OS/390 release that will be made generally available in the first-half of 2000. IBM recommends that customers, currently running MVS releases along with OS/390 in a multisystem complex or Parallel Sysplex environment, plan to upgrade their MVS systems to any release of OS/390 that has been made generally available no later than second-half 1999 and falls within the four consecutive release coexistence period. This will give such customers the maximum flexibility to upgrade their MVS systems to OS/390 in a nondisruptive manner using rolling IPLs. Customers should note that There is a Difference (TM) between how long a release is serviced and how long IBM will ensure toleration and coexistence within a multisystem complex or Parallel Syplex environment. The plan to withdraw coexistence for supported MVS releases with OS/390 will not affect service support for these MVS releases.

Within a Parallel Sysplex environment, the following chart illustrates the JES2 release levels that can all coexist in the same multi-access spool (MAS) with OS/390 Release 6 JES2:

JES2 Level                                             FMID

Version 5.1 HJE5510 Version 5.2 HJE5520 OS/390 Version 1 Releases 1 and 2(6) HJE6601 OS/390 Version 1 Release 3 HJE6603 OS/390 Version 2 Release 4 HJE6604 OS/390 Version 2 Releases 5 and 6(6) HJE6605

(6)   The JES2 functional level is the same.

Within a Parallel Sysplex environment, the following chart illustrates the JES3 release levels that can all coexist in the same JES3 complex with OS/390 Release 6 JES3:

JES3 Level                                             FMID

Version 5.2.1 HJS5521 OS/390 Version 1 Releases 1 and 2(6) HJS6601(7) OS/390 Version 1 Release 3 HJS6603 OS/390 Version 2 Release 4 HJS6604 OS/390 Version 2 Release 5 HJS6605 OS/390 Version 2 Release 6 HJS6606

(7)   Special one-time provision provided to allow OS/390 Release 1
      and Release 2 JES3 to coexist with OS/390 Release 6 JES3.

Specific functions, such as resource affinity scheduling, may only be available on the up-level systems, or it may be necessary to up-level all systems to enable some functions.

Compatibility: OS/390 Version 2 Release 6 is upward compatible from MVS/ESA Version 5 Release 2.2, OS/390 Version 1 Releases 1, 2, and 3, and OS/390 Version 2 Releases 4 and 5.

For information on the levels of JES2 or JES3 that are supported with OS/390 as well as information on compatibility PTFs that may be required, refer to OS/390 Planning for Installation. This publication is also available on the Web at URL:

JES Migration Considerations: For information about JES2 and JES3 migration considerations, refer to OS/390 Planning for Installation.

OS/390 General Migration Considerations: Because the components of OS/390 are integrated into a single package with compatible service levels, customers must install and migrate to an OS/390 release in its entirety before entering into production on that release. For the JES2 or JES3 component, the migration can be staged to remain compatible with other systems.

Customers using the CBPDO (TM) delivery option, will only have to install those elements and features of OS/390 which are at a higher level than their existing system. For example, MVS/ESA SP 5.2.2 customers with DFSMS/MVS 1.4 installed, must install the new OS/390-level of the Base Control Program (BCP), but do not have to reinstall DFSMS/MVS.

Customers who run discretionary work, need to revisit and, possibly adjust their goals for more important work. The changes to WLM algorithms for discretionary work mean that more important work may be more closely managed to customer-specified goals. If the more important work has been consistently overachieving goals, customers may need to adjust the goals to accurately reflect the work's true service-level requirements.

Note: Customers will need to perform normal release-to-release migration activities for any element that they install.

Performance Considerations: Additional information on OS/390 performance will be available at general availability. Customers should consult their marketing representative at or after general availability.

User Group Requirements: Over 350 requirements have been either fully or partially satisfied by the first five releases of OS/390.

Planning Information

Network Computing: OS/390 Version 2 Release 6 contains the WebSphere Application Server for OS/390 (formerly delivered as Domino Go Webserver for OS/390). THE SPECIFICATION OF A SECURITY FEATURE IS REQUIRED -- IT IS STRONGLY RECOMMENDED THAT THE FEATURE WITH THE HIGHEST ALLOWABLE SECURITY LEVEL BE ORDERED AND INSTALLED. A system installed with WebSphere Application Server for OS/390's North America Secure feature must NOT be exported outside the U.S. and Canada to any entities. Systems installed outside the U.S. and Canada should be ordered with WebSphere Application Server for OS/390's Export Security feature. WebSphere Application Server for OS/390 also includes a France feature for import into France. For further information, contact your Export Regulation Coordinator (ERC) or Export Regulations Executive (ERE).

Refer to the Ordering Information sections in the previous and current OS/390 announcements for specific details on feature numbers.

As the cryptographic export regulations are changing, for the most current export regulations, refer to the following Web site URL:



System Integrity

IBM will accept APARs where the installation of OS/390 introduces an exposure to system integrity. Refer to Software Announcement P81-174 dated October 21, 1981.



Security, Auditability, and Control

Data security and auditability in the OS/390 environment are enhanced by the functions available in the RACF part of the optional OS/390 Security Server feature.

B1/C2 Security: The critical operating system components of the OS/390 base and security server and certain optional features, such as MVS/ESA and the optional Security Server feature (includes RACF), continue to be designed to meet the NSA's C2/B1 Trusted Computer Systems Evaluation Criteria. However, some OS/390 functions have not been designed to meet C2 or B1 and when used in conjunction with the above components may have an impact on the C2 or B1 capability of the total system. The impact can only be assessed on an installation-by-installation basis. Consequently, no formal claims about the C2/B1 security of OS/390 can be made. However, the C2/B1 capability of the OS/390 base and security server may be useful in securing certification of some C2/B1 application systems based on OS/390.

Security APARs: IBM will accept Security APARs for OS/390. Security APARs are for reporting problems in existing security mechanisms where the problem descriptions do not meet the precise definition of system integrity, but do constitute an exposure to the security of the system as a whole or to an IBM product which runs on the system. Originally announced in Software Announcement 289-581 dated October 24, 1989.

The customer is responsible for evaluation, selection, and implementation of security features, administrative procedures, and appropriate controls in application systems and communication facilities.
