Description

z/OS V1.6 offers a number of improvements and enhancements that build upon its focus to deliver high qualities of service for enterprise transactions and data, and to extend these qualities to new applications using current software technologies. These improvements include enhancements in application integration, security, availability, scalability, optimization, and networking. At the same time, z/OS continues to improve ease of use and help reduce the total cost of computing.

Some of the functions described in this announcement were previously announced in Software Announcement 204-017 , dated February 10, 2004.

Following is an overview of z/OS V1.6. For more detailed information, refer to z/OS V1R6.0 Introduction and Release Guide (GA22-7502), available on the Internet at

http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/E0Z2A116

Application integration

Deploying applications quickly and easily is important. Therefore, z/OS continues to focus on application integration and deployment. In z/OS V1.6, improvements in this area include:

The new IBM zSeries Application Assist Processor (zAAP) , planned to be available on the IBM zSeries 990 (z990) and zSeries 890 (z890) servers, is an attractively priced specialized processing unit that provides an economical Java execution environment for customers who desire the traditional qualities of service and the integration advantages of the zSeries platform.
When configured with general-purpose processors within logical partitions running z/OS, zAAPs may help increase general-purpose processor productivity and may contribute to lowering the overall cost of computing for z/OS Java technology-based applications. zAAPs are designed to operate asynchronously with the general-purpose processors to execute Java programming under control of the IBM Java Virtual Machine (JVM). This can help reduce the demands and capacity requirements on general-purpose processors which may then be available for reallocation to other zSeries workloads.
The IBM JVM processing cycles can be executed on the configured zAAPS with no anticipated modifications to the Java applications. Execution of the JVM processing cycles on a zAAP is a function of the Software Developer's Kit (SDK) 1.4.0 (5655-I56) for zSeries, z/OS V1.6, and the Processor Resource/Systems Manager™ (PR/SM™). Refer to Software Announcement 204-178 , dated August 10, 2004 (IBM 64-bit SDK for z/OS, Java 2 Technology Edition, V1.4).
z/OS UNIX^® Systems Services now provides condition variables in shared memory and superkill support. It also offers enhancements to the automount daemon, Euro symbol support, and Unicode.
OpenSSH is included in IBM Ported Tools for z/OS (5655-M23), as announced in Software Announcement 204-109 , dated May 25, 2004. OpenSSH is a widely accepted tool for secure login and file transfer using OpenSSL technology. With OpenSSH, z/OS servers and other servers can communicate in a security-rich environment using ssh.

C/C++ enhancements in z/OS V1.6 include:
- Improved scalability using the z/OS 64-bit C/C++ environment for developing and deploying applications that need to process large data objects. The C/C++ compiler supports the industry-standard LP64 programming model, to allow exploitation of virtual memory above the 2-GB bar.
- C/C++ support for developing, porting, generating, and debugging high-performance and complex 64-bit virtual applications.
- A new keyword to specify the alignment of a variable, to help port applications to z/OS and to aid in improving performance.
- Two new C/C++ compiler options, ARCH(6) and TUNE(6), which allow for exploitation of the new z990 and z890 hardware features for potential performance improvements.
- New C/C++ compiler invocation commands that allow for use of a configuration file for running under z/OS UNIX. These commands provide increased portability and stability in migrating to future releases of the compiler.
- The C/C++ DEBUG option now supports debugging 64-bit applications, and the debug information can be used by dbx under z/OS UNIX.
Note: The C/C++ ISPF panels and the Dynamic Link Library Rename (DLLRENAME) Utility have been removed from the C/C++ without Debug Tool feature of z/OS V1.6.
Lightweight Directory Access Protocol (LDAP) — z/OS V1.6 enhancements for application integration within LDAP will also be made available within the LDAP Enhancements for z/OS V1R4/R5 and z/OS.e V1R4/R5 Web deliverable.
New enhancements include:
- Peer-to-peer replication provides fail-over support for server availability. If a primary master server fails, there is now a backup master to which LDAP operations can be directed.
- Event notification provides an event notification/persistent search mechanism for applications, directories, and meta directories, which enables them to be notified when a directory change has occurred.
- Large group support helps you improve LDAP server performance when maintaining large access groups containing many members. This is likely to help you if you are using IBM Tivoli^® Access Manager for e-business with a z/OS LDAP registry.
Previously announced enhancements for LDAP, found in Software Announcement 204-017 , dated February 10, 2004, that will be included in both z/OS V1.6 and within the LDAP Enhancements for z/OS V1R4/R5 and z/OS.e V1R4/R5 Web deliverable are:
- LDAP Client Support of 64-bit Addressing
- Change Log support
- Alias Support
- DB2^® Restart/Recovery
- Dynamic Nested Groups
- Enhanced Schema Support for merge capabilities
- LDAP Server support of IPv6
- Search Results Cache
IBM XML Toolkit for z/OS V1.7 (5655-J51) provides the latest eXtensible Markup Language (XML) parser and eXtensible Stylesheet Language Transformations (XSLT) processor support for C++, as announced in Software Announcement 204-181 , dated August 10, 2004. IBM XML Toolkit for z/OS V1.7 is designed to help you create, integrate, and maintain business-to-business (B2B) solutions.

The High-Level Assembler element of z/OS V1.6 contains all the functions of High-Level Assembler V1.5 (5696-234), announced in Software Announcement 204-122 , dated June 8, 2004. High-Level Assembler is a powerful and flexible tool for application development. High-Level Assembler V1.5 includes support for new z/Architecture instructions, better control of conditional assemblies, Dynamic Link Library (DLL) support, z/OS UNIX enhancements, and improved ASCII support. High-Level Assembler and its Toolkit feature can also help improve programmer productivity and application reliability and maintainability, through better usability and diagnostics. For more information, refer to the announcement.
z/OS Communications Server enhancements include:
- X Window System and OSF/Motif support upgrade: X Window System Version 11 is upgraded to Release 6.6, and OSF/Motif libraries are upgraded to OSF/Motif 2.1.30. Along with many new features, a key element of this upgrade is that applications can take advantage of 64-bit addressing mode for these APIs.
- FTP Client API support provides a callable programming interface you can use to invoke the z/OS FTP client from Assembler, COBOL, and PL/I applications.
- FTP Enhanced Multibyte Character Set (MBCS) support improves character set conversion support for the double-byte character set (DBCS) code pages.
Interactive Structured Programming Facility (ISPF) includes several panel language enhancements and other software development tools for more productive and flexible program development:
- ISPF panels now support inline REXX commands. This lets you use the power of the REXX language to perform tasks like processing variables and screen input, and performing arithmetic functions and input field validation. You can also store complex and commonly used REXX functions in execs, and call them from any number of panels. This support can help you reduce ISPF application development cost and improve productivity.
- Do and If-Then-Else support and new table handling commands allow file-tailoring skeletons to be coded more easily.
- New display features in the ISPF editor make it easier to view and change data more effectively, with less scrolling.

Security

z/OS V1.6 can provide greater security for enterprise and Web-based applications with Multilevel Security auditing and enhancements to RACF^®, Network Authentication Server, Enterprise Identity Mapping (EIM), Secure Sockets Layer (SSL), and Integrated Cryptographic Service Facility (ICSF). In addition, LDAP supports 64-bit addressing and IPv6 communication.

Security Server (RACF) improvements:
- The RACF Class Descriptor Table (CDT) is now designed to be updated without an IPL, and these updates no longer require corresponding RACF Router Table changes. This can allow system administrators to add or remove installation-defined classes more quickly. Also, this can help application developers who want to exploit RACF security services for new applications using new RACF classes to deploy them more quickly.
- Multilevel Security extends RACF auditing capability to allow administrative auditing controls to be based on user-friendly security labels (SECLABELs). This adds to the Multilevel Security functions provided in z/OS V1.5. For more information about Multilevel Security, refer to the overview in Software Announcement 202-190 , dated August 13, 2002.
- RACF will use LDAP change log support to create event notifications when a user profile is changed in RACF. A change log entry can be created by RACF regardless of whether LDAP or RACF commands are used to modify a RACF user.
- RACF now supports recoverable user passwords. Passwords can be stored in digitally encrypted PKCS#7 formatted envelopes that can be recovered by authorized applications. Users, and groups of users, can be selectively enabled for this new function. RACF can create an LDAP change log entry that will act as a notification of the password change, and LDAP clients can request the password envelope from RACF using LDAP interfaces.
  IBM Tivoli Directory Integrator, 5.1.2 (5724-D99), will provide exploitation of this z/OS function to enable enterprise-wide password synchronization in which z/OS is an equal participant, without requiring z/OS-specific agents or exits.
LDAP improvements:
- The LDAP Client APIs now support 64-bit addressing. LDAP C/C++ applications running on zOS V1.6 can also exploit 64-addressing.
- The LDAP Server, LDAP Operational Utilities, and Client APIs now support the IPv6 standard for TCP/IP communication.
- The LDAP Change Log provides a log of changes made to entries in the directory, which can include RACF password and user profile changes. The log of changes can be searched by a client. It also enables metadirectory products like IBM Tivoli Directory Integrator that work from a change log to work with the z/OS LDAP server.
- Alias Support provides a way for one directory entry to point to another. An alias entry can provide a convenient, easy-to-use name for an entry or subtree so that users do not have to use a potentially more complex real name. It can also help avoid the need to duplicate an entry in multiple subtrees.
- LDAP RAS characteristics are improved by allowing the LDAP server to remain active when DB2 is restarted.
- Dynamic and Nested Group support allows a group administrator to define group membership in terms of attributes, and lets the directory determine who is or is not a member. It also allows administrators to construct and display group hierarchies that describe group memberships. This can make it easier and faster to administer groups.
- Search results are now cached, which can enhance LDAP server performance. Cache tuning and monitoring capabilities are also provided.
- Enhanced Schema Support helps reduce the complexity inherent in schema updates and enables schema modification by replacement of individual attribute values. This can effectively merge new attribute values into existing schema.
Network Authentication Server and Enterprise Identity Mapping (EIM):
- Network Authentication Server interfaces are enhanced to provide support for 64-bit callers. Other APIs, as well as tracing enhancements, are included.
- EIM can now be "policy driven" to help simplify administration for large numbers of users who require the same target userid. Administrators can define policies that can act as default mappings, which can help to streamline administration of users.
Secure Sockets Layer (SSL) enhancements:
- System SSL is enhanced to support industry standards, certificate administration, and 64-bit addressing to enable communication in a security-rich environment through the SSL/Transport Layer Security (TLS) protocol across distributed environments. System SSL is planned to be enhanced to support the use of Diffie-Hellman key exchanges during the SSL/TLS handshake. To ease the administrative task of sharing certificates, the gskkyman command can now allow complete certificate chains (not just single certificates) to be exported and imported using PKCS#7 format files.
z/OS Communications Server IP provides security enhancements, including:
- Broadcast Control: Support is added to let you use SAF security controls to specify whether an application can set the SO_BROADCAST socket option needed to send broadcast datagrams.
- TCP/IP profile checks: Enhanced checking during profile processing to check the consistency of configuration information related to multilevel security.
- Support for running multiple copies of the sendmail daemon, each with a different security label (SECLABEL).
- Support for binding the Trivial File Transfer Protocol daemon (TFTPD) to a specific IP address. This lets you run multiple copies of TFTPD with different security labels.
DFSMS now supports multilevel security labels (SECLABELs) in automatic class selection (ACS) routines. You can code ACS logic to direct data set allocations for different security classifications to different sets of volumes. If you currently use allocation exits to provide this function, you can replace them with this new IBM-supported function.
Integrated Cryptographic Service Facility (ICSF) provides application programs with callable service interfaces to support the encryption and decryption of data using the cryptographic hardware in the zSeries servers. ICSF adds support for callers running in 64-bit addressing mode. ICSF support for AMODE(64) callers is planned to be available in the ICSF 64-bit Virtual Support for z/OS V1R6 and z/OS.e V1R6 Web deliverable in December 2004. This support is planned to be included in z/OS V1.7. A limited set of callable services for AMODE(64) callers will be supported on z990, z900, z800, and z890 processors. They are intended to support System SSL, WebSphere^®, and Java.

Availability

Reliability is a zSeries hallmark. Application and network availability are crucial to the success of your business. Enhancements in z/OS V1.6 that can help you improve availability include:

The RACF Class Descriptor Table (CDT) is now designed to be updated dynamically without an IPL. For more information, refer to Security in the Description section.
Resource Recovery Services (RRS) enhancements: Resource managers can now be restarted on any z/OS V1.6 system in the same RRS logging group within a sysplex while RRS continues to run on the system where they were originally started. This is designed to allow you to move resource managers between systems without impacting other applications that might be using RRS.
Improved zFS address space availability: Diagnostic data collection will proceed in parallel with other processing, and the address space will remain available to process mounted zSeries File Systems (zFS). This can help improve availability for subsystems and applications using zFS. Also, starting in z/OS V1.6, zFS parameters can be specified in multiple parmlib members.
Support for renaming LPARs designed to be provided without an outage , which can help you eliminate planned outages for power-on resets.
Improved diagnostic data collection for FICON™ , which makes it easier to identify the root causes of FICON errors. This can help lower your service costs and improve availability.
A new restartable PDSE address space , which helps you avoid unscheduled IPLs to recover from failures in PDSE processing.
Improved latch contention detection in the z/OS UNIX Systems Services environment .
A number of system limits have been raised:
- The maximum number of CPs per LPAR is increased from 16 to 24.
- The size of SMF buffers is increased from 256 MB to 1 GB.
- The maximum number of XCF members in a group is increased from 1023 to 2047.
- The maximum number of file descriptors per UNIX process is increased from 64 K to 128 K.
- The number of Linkage Index (LX) entries is increased from 2 K to 32 K.
Virtual storage constraint relief for programs that use Execute Channel Program (EXCP) .
z/OS Communications Server availability improvements include:
- Separate address space for TN3270 servers: The TN3270 server can now be run in its own address space, which can allow you to control TN3270 functions separately from the TCP/IP stack. The TN3270 server's performance goals can be set separately; it can be stopped and restarted without necessarily affecting other networking functions or availability; and problem diagnosis is simplified.
- Alternate route selection for SNA and Enterprise Extender (EE): VTAM^® allows alternate route selection for sessions using Enterprise Extender (EE) connection networks when connectivity fails due to temporary conditions in the underlying IP network. This can help improve availability for sessions using EE connection networks.
- Dynamic major node definition changes: New configuration support for EE XCA major nodes allows activation and inactivation at the GROUP level. In addition, the EE XCA major node now supports configuration updates when the major node is active. This provides flexibility and can help improve availability by allowing updates to occur without necessarily affecting existing sessions.
- VTAM persistent sessions forced takeover: VTAM applications that support persistent sessions can initiate an application takeover without waiting for a planned takeover exchange between the participating applications. This can help improve availability when SNA application recovery is needed.
- SMTP server resilience: When the new optional configuration statement DELETEBADSPOOLFILE is specified in the SMTPPROC configuration data set, the SMTP server is designed to delete bad spool files that would otherwise cause an error when accessed by SMTP, and continue to run. The default behavior if this statement is not coded is that SMTP will generate an error message and terminate.
TCP/IP Sysplex autonomic enhancements:
- TCP/IP protocol stacks in a sysplex are enhanced with autonomic functions that can help improve availability for server applications that use Dynamic Virtual IP Address (DVIPA) technologies in a z/OS sysplex environment:
  - TCP/IP automatic takeover: TCP/IP protocol stacks configured for sysplex functions using Dynamic Virtual IP Addresses (DVIPAs) will now perform proactive self health monitoring designed to detect severe shortages of key resources and failure of key components required for proper operation of DVIPA functions in a sysplex environment. If a TCP/IP stack detects a key component failure, it is designed to remove itself from the sysplex, allowing a healthy backup TCP/IP stack to take over. This can help improve availability of key server applications.
  - Dynamic coordination of DVIPA ownership transfers: When a TCP/IP protocol stack is started, it performs "take back" processing for any DVIPAs for which it is designated as the primary owner. Now, the TCP/IP stack will delay this "take back" processing until the OMPROUTE routing daemon has been activated. This delay can allow the routing updates that reflect the movement of the DVIPA to be immediately advertised to the network when the transfer of the DVIPA is initiated. As a result, the impact that a DVIPA movement might have on network clients and the need for complicated automation scripts can be significantly reduced.

Scalability

z/OS is a highly scalable operating system that can support the integration of new applications.

Scale up and scale out: You can scale up, in a single logical partition, and scale out, in a parallel sysplex, for higher availability. With z/OS V1.6, up to 24 processors are supported in a single logical partition on the z990 server. In 2005, IBM plans to provide support for z/OS V1.6 to run up to 32 processors in a single logical partition on a z990 server.

Note: When you are using the new IBM eServer^® zSeries Application Assist Processor (zAAP), which provides a specialized z/OS Java execution environment, the total number of processors defined in a z/OS logical partition is the sum of general purpose processors (CPs) and zSeries Application Assist Processors (zAAPs).

z/OS 64-bit exploitation: z/OS V1.6 is designed to deliver the capability to exploit 64-bit virtual in developing and deploying applications that require significantly more data addressability. This is provided through enhancements to UNIX Systems Services, including the dbx debugger, 64-bit Language Environment^® run-time support, the existing C/C++ compiler 64-bit support, and Program Management Binder 64-bit support. This support completes the major steps of the z/OS 64-bit virtual roadmap.

Other scalability enhancements:

SMS support for Parallel Access Volumes (PAVs) can allow you to direct allocations for data sets with high performance requirements to PAVs automatically. This can help you reduce I/O bandwidth bottlenecks and better use your direct access storage. It is designed to also provide significant performance improvements, especially for DB2 data.
DFSMShsm™ secondary space management has been changed to use multitasking. This can help you to reduce the time needed for secondary space management functions of migration cleanup and migration from ML1 DASD to ML2 tape.
IBM 64-bit SDK for z/OS , Java 2 Technology Edition, V1.4 (5655-I56) provides a full-function Software Development Kit (SDK) at the Java 2 technology level, compliant with the Sun SDK 1.4 APIs. With 64-bit SDK for z/OS, Java 2 Technology Edition, V1.4, you can run Java applications that were previously storage constrained.

Optimization

Self-optimization is important because it can help free you from having to manage system resources while making effective use of them. z/OS V1.6 offers these new self-optimizing capabilities:

Workload Manager (WLM) has been enhanced to provide 64-bit virtual storage support for WebSphere. This enables some services to run in 64-bit mode. No application changes are expected to be needed in order to exploit this function.
DFSMSrmm™ now supports client systems and has added an object-oriented programming interface. These enhancements can allow you to use DFSMSrmm to manage all the tapes in your z/OS enterprise environment to help you to make better use of tape resources.

Networking

z/OS V1.6 offers networking improvements in several areas:

Job-specific source IP addressing: New z/OS TCP/IP function provides the ability for applications connecting outbound to use a specific source IP address. This can help provide flexibility and ease administrative tasks for TCP/IP connections originating from a single z/OS system or a z/OS sysplex environment. For example, firewall administration can now be simplified, as TCP/IP connections originating from applications running in a z/OS environment can easily be identified by a predictable source address.
Enhanced IPv6 support: z/OS Communications Server includes IPv6 support for key functions, extending them into the next generation of the Internet:
- Dynamic VIPA and Sysplex Distributor
- Sysplex Sockets
- OMPROUTE support for OSPFv3 described in RFC2740
- The TCP/IP SNMP Subagent:
  - Version-neutral support in the TCP/IP Enterprise Specific MIB
  - Updates to standard MIB data from the following IETF Internet drafts: IP-MIB, IP-FORWARD-MIB, and the TCP-MIB
Enterprise Extender (EE) and Systems Network Architecture (SNA) offer new function and serviceability improvements:
- You can now activate or deactivate an entire EE definition GROUP with a single VARY command. This can help you simplify automation routines and operations.
- A new display command for EE provides general and connection-specific performance information.
- As an aid in EE problem diagnosis, the TCP/IP packet trace formatter is enhanced to include the formatting of EE packets that flow to and from TCP/IP.
- A new command terminates hung Advanced Peer-to-Peer Networking^® (APPN^®) searches to allow new search requests to complete.
- A new VTAM start option controls the display of additional diagnostic information when an APPN locate search fails.
- New VTAM configuration controls let network administrators control the passing of IP characteristics (via CV64) associated with logical units (LUs) that represent a TN3270 session.
- New configuration options provide the ability to control how cross-subnetwork high performance routing (HPR) Rapid Transport Protocol (RTP) connections are established through APPN border nodes. You can use these controls to force HPR to terminate RTP connections at border nodes to maintain awareness of cross-subnetwork sessions.
- When an HPR pipe stalls because of error conditions, extended recovery attempts will be activated and the operator informed.
- Growth constraints are designed to be removed for HPR pipes with the extension of network element address allocation above the 64K line, up to 33M.
- As an aid in HPR problem diagnosis, a new IPCS VTAMMAP command option is provided.

Ease of use

z/OS continues to improve ease of use in many areas. z/OS V1.6 provides these usability improvements:

Hardware Configuration Manager (HCM) now provides Chpid Mapping Tool (CMT) support and offers an enhanced configuration diagram. More user fields for HCM objects are supported, and a "Save As" function is added to the switch port list in the Director dialog and to the "List Devices for OS Configuration" dialog. Besides the existing cropping, HCM now provides a second, enhanced diagram cropping function.
Dynamic Deletion of Bound Aliases lets you back out of assigned aliases and dynamically migrate from configurations. Implementing this function can help reduce complexity by providing a migration tool to migrate to sub-channel sets.
DFSMSdss™ now supports a REPLACEUNCONDITIONAL keyword for copy and restore operations. Using this new keyword, you can copy, rename, or restore data sets to replace existing data sets. This can help improve system programmer and storage administrator productivity. Support is also provided via PTF for z/OS V1.2, z/OS V1.3, z/OS V1.4, z/OS V1.5, and OS/390^® V2.10.
The DFSMSrmm ISPF dialog has been enhanced to support line commands on more search results list panels, use of CLISTs for dialog-initiated searches, and saving and reusing field values. These enhancements can help improve DFSMSrmm's ease of use, tape administrator productivity, and tape resource management.
New z/OS UNIX shell commands are added:
- The clear command allows you to clear the UNIX shell environment screen.
- The uptime command allows you to determine the date and time of the last IPL.

Total cost of computing

z/OS V1.6 can help to reduce the cost of computing by supporting new technologies that can help reduce your dependence on older hardware.

OSA-ICC (OSA3270) support lets you use Telnet-based consoles to replace expensive locally-attached 3270 control unit emulation hardware. The Telnet-based consoles support early IPL phases to provide the ability to recover from unexpected errors. This can help reduce your cost for small systems, and make it easier for you to migrate to newer processors, particularly when you migrate from a Multiprise^® processor with an integrated console.

Statement of direction

IBM statement of direction update on SNA support in 2004:

It is IBM's intent to support VTAM in z/OS Communications Server for the foreseeable future. Customers have a substantial investment in 3270 and SNA applications. We continue to support and enhance VTAM's capabilities while integrating it with new technologies. IBM has no plans at this time to discontinue SNA support in z/OS Communications Server. As of June 2004, customers can, for selected SNA workloads, use Communications Server products for Linux™, Linux on zSeries, Microsoft™ Windows™, and AIX^® to replace some of the old SNA infrastructure components, such as the IBM 3745/46 or other channel-attached SNA controllers. z/OS Communications Server can replace some SNA Network Interconnect (SNI) workloads using Enterprise Extender and Extended Border Node functions.
It is IBM's intent to introduce an additional solution in 2005 that uses NCP (Network Control Program) software running within Linux on zSeries. The intent is to provide a migration path for customers who use traditional SNA (including SNA Network Interconnect (SNI)) to communicate with their business partners. This solution can allow them to continue using traditional SNA without a dependency on IBM 3745 and 3746 Communications Controller hardware.

Notable change: With z/OS V1.6, Text Search is no longer made available as a base element of z/OS. Instead, it will be made available for Web download as z/OS and z/OS.e Text Search under a restricted license. This is a change to the statement of direction made in Software Announcement 203-266 , dated October 7, 2003, which stated that with z/OS V1.6, the Text Search base element would be removed and no replacement would be provided. The Text Search element has been removed from the z/OS product. However, the Text Search function is still required and licensed for use only for DB2 UDB Text Extender feature of DB2 Universal Database^® for z/OS, Program Number 5625-DB2, as a Web deliverable named z/OS and z/OS.e Text Search.

Before you use the DB2 UDB Text Extender feature, you must download and install the z/OS and z/OS.e Text Search Web deliverable on z/OS V1.6.

IBM plans to take the following actions effective with z/OS V1.7:

Support for ISAM data sets will be withdrawn. When this support is withdrawn, you will no longer be able to process ISAM data sets other than to delete them. The ISAM Compatibility Interface will remain available to help you migrate applications to VSAM without application changes.
Support for JES2 compatibility mode will be withdrawn. As of z/OS V1.7, JES2 will no longer support compatibility with pre-z/OS V1.2 systems. The $ACTIVATE command, which converts the JES2 checkpoint from z2 mode to R4 mode (compatibility mode), will be removed. Before installing z/OS V1.7, you will need to do one of the following:
- Use the $ACTIVATE command to convert the JES2 checkpoint to z2 mode
- Offload the SPOOL, cold start JES2 z/OS V1.7, and reload the jobs on the new SPOOL
The z/OS Optional Source Code media features will not be offered in z/OS V1.7. The last release offering these materials will be z/OS V1.6 and z/OS.e V1.6. These features contain macros and source code for some programs in the z/OS BCP, BDT base, BDT SNA NJE, BDT File-to-File, DFSMS, MICR/OCR, BCP JPN, and Security Server RACF elements.
Support for the STEPCAT and JOBCAT JCL statements will be withdrawn. There are other facilities in DFSMSdfp™ that allow catalog requests to be directed to specific catalogs, and the utility of these two JCL statements has been drastically reduced by the implementation of System-Managed Storage and the placement of Unit Control Blocks (UCBs) above the 16 MB line. When this support is withdrawn, any remaining JCL that uses these two statements will have to be changed.
The OS/390 V2.10 C/C++ compiler is planned to be removed from the C/C++ without Debug Tool feature, leaving only the ISO C/C++ compiler. Since z/OS V1.2, the OS/390 V2.10 C/C++ compiler has been shipped in addition to the strategic ISO C/C++ compiler that is also provided with z/OS. This OS/390 V2.10 C/C++ compiler serves as a migration aid to the newest ISO C/C++ compiler.

IBM plans to take the following action effective in 2005:

IBM intends to provide a VSAM Java database connectivity (JDBC) Connector. A JDBC Connector implements a Java application programming interface that is designed to allow you to write Java-based applications that read and write VSAM data without having to do VSAM programming or use copies of existing data. These applications can access VSAM data, at the same time as other applications, when deployed in WebSphere, DB2, and UNIX Systems Services environments. When used with the optional DFSMStvs (Transactional VSAM Services) feature, the VSAM JDBC Connector can allow WebSphere applications to participate in coordinated commit processing.

IBM plans to take the following actions in a future release:

Support for the VSAM IMBED, REPLICATE, and KEYRANGE attributes will be withdrawn. No supported release of z/OS or OS/390 allows you to define new VSAM data sets with these attributes. Using them for existing data sets can waste DASD space and can often degrade performance. When this support is withdrawn, you will not be able to process data sets with these attributes.
The English and Japanese ISPF panels will be removed from DFSORT™. This limited function interactive facility will no longer be provided, and there will be no replacement. All other previously supported methods for invoking DFSORT will still be supported, such as batch invocation and invocation from a program.

Preview: z/OS^® V1.7

Previews provide insight into IBM plans and direction. Availability, prices, ordering information, and terms and conditions will be provided when the product is announced.

Note: This statement represents current intentions of IBM. IBM development plans are subject to change or withdrawal without further notice.

Application integration

Earlier this year, IBM announced that Hierarchical File System (HFS) function is stabilized. The zSeries^® File System (zFS) is the strategic UNIX^® Systems Services file system for z/OS. IBM plans to enhance zFS function in z/OS V1.7 so that you can use zFS file systems at all levels within the file hierarchy.

With z/OS V1.7, the C/C++ Compiler and Language Environment^® plan to support the ISO C99 standard. This support is expected to include new language features and library functions designed to improve the usability of the programming environment and portability of programs across different platforms.

Security

Planned improvements for security include:

Integrated IPSecurity support: Communications Server support is planned for IP filtering, Internet Key Exchange (IKE), and Virtual Private Network (VPN), without requiring use of the Integrated Security Services Firewall Technologies. These integrated functions are expected to help improve network security configuration, monitoring, scalability, and performance. The Policy Agent can be used as a central configuration point for filter rules and VPN rules. The Traffic Regulation Management Daemon (TRMD) will be enhanced to log IPSec events.
Security Server (RACF^®) improvements: Security Server support is planned for mixed-case passwords. This will allow a greater number of combinations for passwords, which can help provide improved security and better compatibility with other platforms.

Availability

Planned improvements in availability for z/OS V1.7 include:

TCP/IP Sysplex Autonomics: z/OS Communications Server plans to continue delivering autonomic capabilities designed to optimize performance and maximize availability with less need for operator intervention. These enhancements are planned:

Self-optimizing:
- Sysplex Distributor will distribute incoming traffic to target stacks within a sysplex using optimal available IP routes. This allows the use of high-speed interfaces such as OSA Express Gigabit Ethernet. In addition, it removes a restriction: Sysplex Distributor need no longer use only dynamic XCF interfaces for packet forwarding.
- Sysplex Distributor will exploit new z/OS WLM support to help optimize workload balancing for TCP/IP servers in a sysplex. Sysplex Distributor will use server-specific recommendations from WLM that reflect how well target servers meet their service class goals.
Self-healing — Sysplex Distributor will use key performance indicators such as connection backlog queues to supplement existing measurements and WLM recommendations. This will help improve load balancing.
Self-configuring — TCP/IP will be able to rejoin a sysplex once problems that have triggered an automatic takeover have been resolved. When a stack rejoins a sysplex, it can automatically restore its original configuration and resume ownership of any Dynamic Virtual IP Addresses (DVIPAs) for which it is the primary owner. This expands on the TCP/IP Automatic Takeover function introduced in z/OS V1.6.
Self-protecting — The new z/OS Load Balancing Advisor will make sysplex information available to network-based load balancers (such as content switches and load balancing appliances), so that they can make better load balancing decisions.
This helps protect busy target servers in a sysplex from being overloaded with new requests when they are already in danger of failing to meet their WLM service class goals or lack displaceable capacity.
By helping meet WLM goals in a sysplex while allowing you to take advantage of network-based load balancers, z/OS Load Balancing Advisor helps maximize availability and optimize performance.

TCP/IP Sysplex operational enhancements: New TCP/IP configuration options and operator commands will help improve operational tasks for TCP/IP stacks in a sysplex and remove the need to manage OBEYFILE profiles.

When a TCP/IP stack has been removed from a sysplex, a configuration option and an operator command will allow the stack to rejoin the sysplex and restore its configuration.
A new command will be provided to activate and deactivate a DVIPA, so that a TCP/IP stack can easily obtain or relinquish ownership.

Scalability

Scalability enhancements for z/OS V1.7 are planned to include:

Sequential and EXCP data sets larger than 64K tracks will be supported. (This is in addition to existing support for extended format sequential data sets larger than 64K tracks.)
More than 255 extents per VSAM component will be supported.

These changes are expected to provide you greater flexibility when using larger volumes and reduce the frequency with which you need to defragment volumes.

Optimization

Self-optimizing capabilities planned for z/OS V1.7 include:

Virtualization Engine™ support: Building on IBM mainframe leadership and strong 35-year heritage of virtualization across IBM systems, IBM Virtualization Engine helps to enrich these innovative competencies across the entire IBM and TotalStorage^® portfolio to help further simplify and optimize the management of a heterogeneous IT infrastructure. The Virtualization Engine was previewed by IBM in Software Announcement 204-096 , dated April 28, 2004. These innovative offerings provide a key component of the on demand operating environment, addressing a wide range of user needs, ranging from provisioning to workload management (IBM Enterprise Workload Manager) and system management.
IBM Virtualization Engine is a suite of systems services and technologies that can help your business improve the effectiveness of IT as it treats resources of individual servers, storage, and networking products to function as a single pool or entity, allowing access and management of resources across an organization more efficiently, by effect and need rather than physical location. Virtualization is a key component of the on demand operating environment, which can help you align your IT environment more effectively with the needs of your business.
z/OS plans to extend its role in cross-system optimization with capabilities in support of the IBM Virtualization Engine. IBM plans to deliver Enterprise Workload Manager support for z/OS in 2005. IBM also intends to deliver Common Information Model (CIM) support on z/OS in 2005. This set of open interfaces enables cross-platform systems management solutions.
Enhancements for WLM
- Sub Capacity Report Tool (SCRT) Extensions For Dedicated CPUs are planned to provide a 4-hour rolling average of real consumed CPU time without wait time, independent of LPAR configuration. This is designed to allow you to determine the actual software cost for systems running either in LPAR mode or as VM guests when VM is running in one or more LPARs.
- CPU capacity on demand: New System Resource Manager (SRM) support is planned to allow you to perform processor capacity upgrades and downgrades in a more granular way than by adding or removing entire CPs. SRM will be designed to react to nondisruptive processor speed changes to support Sub-Capacity Processors, dynamically adjusting to real processor capacity on demand.
XRC+ and Geographically Dispersed Parallel Sysplex™ (GDPS™) enhancements are planned to allow log data managed by the System Logger to be replicated to a remote location. In the case of a disaster, log data is expected to be available at the remote location along with the database it corresponds to. This is expected to help improve recovery time and reduce data loss.
CICS^® sockets enhancements are planned to improve application performance by:
- Allowing CICS sockets to use the CICS Open Transaction Environment (OTE). This is designed to reduce task switching in CICS environments.
- Helping to reduce the overhead of CICS sockets tracing and monitoring processing when these facilities are not activated.
- Allowing the IP CICS Sockets Task-Related User Exit (TRUE) to be loaded above the 16MB line, providing virtual storage constraint relief.

Ease of use

Planned improvements include:

IBM Health Checker for z/OS and Sysplex will be a new z/OS base function. An IBM Health Checker for z/OS and Sysplex tool has been provided as a Web download; positive customer response led IBM to integrate and enhance it. IBM Health Checker for z/OS and Sysplex provides a foundation to help simplify and automate verification of best practices for z/OS and sysplex configuration values. It compares active values and settings to those generally recommended or to those you specify for your installation. IBM Health Checker for z/OS and Sysplex consists of:

The Framework is a started task designed to manage functions such as check registration services, messaging, scheduling, command processing, logging, and reporting. The Framework has a fully-documented programming interface designed to let anyone write a check for it to perform.
Checks are provided separately and are independent of the Framework. Checks can be added to the system dynamically. You can provide overrides to check defaults using HZSPRMxx parmlib members or MODIFY operator commands. You can also use MODIFY commands to display the status of checks and dynamically change their status and parameters.
IBM plans to update checks currently available from the Web download tool to support the IBM Health Checker for z/OS and Sysplex framework and provide them in PTFs.
Examples of checks include:
- Virtual storage configuration, which also highlights changes from IPL to IPL
- Real storage settings that affect RSM processing
- Couple data set configuration
- Coupling facility connectivity and CF structure placement
- XCF configuration definitions
- Console definitions
- z/OS UNIX file system configuration

IBM Health Checker for z/OS and Sysplex framework is also planned to be made available for z/OS releases V1.4, V1.5, and V1.6 as a z/OS Web download. Before that time, you can download the current IBM Health Checker from

http://www.ibm.com/servers/eserver/zseries/zos/downloads/

Starting with z/OS V1.7, SDSF will support IBM Health Checker for z/OS and Sysplex. It will make managing your checks easier with a new Check (CK) panel. You will be able to use the CK panel to

Display checks, attributes, and status, taking advantage of standard SDSF sort, filter, and arrange support
Alter check attributes (such as status, interval, severity, category, and WTO descriptor)
Browse check output for the most recent check
Print check output or sent it to a data set

Related information

IBM Tivoli^® NetView^® for z/OS V5.1 (5697-ENV) (with APAR OA06856) offers new Intrusion Detection Services (IDS) support designed to improve your z/OS network security. NetView IDS support is based on z/OS Communications Server Intrusion Detection Services. Communications Server's IDS is intended to complement traditional network-based IDS devices.

There is a growing realization that more attacks come from inside than in the past--not only attacks from insiders, but attacks from compromised machines inside the enterprise. IDS provides more protection in areas that cannot be covered well by traditional network-based IDS devices, such as routers. NetView Message Automation for Intrusion Detection is designed to

Generate alerts, notify Tivoli Risk Manager, send NetView operator messages, and send e-mail notifications when attacks are detected. The notifications can be customized for your installation, and additional data or statistics about the intrusion can be included.
Issue commands to collect more data. Responses and messages are logged, and can be sent via e-mail to a designated receiver.
Collect summary statistics based on the type of intrusion or event.

Also, you can set a threshold to help prevent IDS message flooding.

Enabling optionally priced features: z/OS optionally priced features use a z/OS product registration service, together with product policy statements, to determine whether or not the z/OS priced feature has been ordered and should run. Optionally priced features that are ordered concurrently with z/OS will be shipped by IBM together with policy statements in PARMLIB that enable the ordered priced features. z/OS priced features that have not been ordered will also be shipped with z/OS, but with policy statements that 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 z/OS license as described in the z/OS Licensed Program Specifications (GA22-7503). Customers must notify IBM when they enable an optional feature that was shipped disabled. A detailed description of the enablement support is available in z/OS and z/OS.e Planning for Installation (GA22-7504).

Program services

Central service for suspected defects in z/OS code is provided by the IBM Support Center within the customer's geography. On-site (local) support, although available in many geographies, is provided as part of IBM's portfolio of fee-based services.

Coexistence and migration rules should be taken into account in planning future migrations. Refer to the General coexistence, release migrations, and fallback section in the Technical information section for additional information.

Technical information

Hardware requirements

z/OS V1.6 runs on the following IBM servers:

zSeries z900 or z990, or equivalent
zSeries z800 or z890, equivalent

Software requirements

The z/OS base is a system that can be IPLed. There are no software prerequisites in order to IPL. Specific functions may require additional products not included in the z/OS base, or in the optional features of z/OS. Refer to z/OS and z/OS.e Planning or Installation (GA22-7504) for a listing of specific software requirements at

http://www.ibm.com/servers/eserver/zseries/zos/bkserv/find_books.html

Coexistence, release migrations, and fallback

z/OS and z/OS.e give you compatibility and flexibility as you migrate systems in a multisystem configuration by allowing several releases of z/OS or z/OS.e to coexist. This includes non-Parallel Sysplex^® and Parallel Sysplex multisystem configurations.

Coexistence allows systems within a multisystem configuration to be upgraded to a new release level of z/OS one system at a time. This is contingent on the fact that the release you are migrating to can coexist with the lowest release running in your multisystem configuration.

z/OS is coexistence-supported with its equivalent z/OS.e release (as well as any z/OS.e releases equivalent to any coexistence-supported z/OS release). As such, z/OS.e supports the same migration policy as z/OS.

Starting with z/OS V1.6, the Coexistence-Migration-Fallback policy aligns with the Service policy. The intention of this policy is to simplify and provide greater predictability to aid in release migrations. IBM intends to continue with the practice of providing service support for each release of z/OS or z/OS.e for three years following its general availability (GA) date. IBM, at its sole discretion, may choose to leave a release supported for more than three years. This Coexistence-Migration-Fallback policy is effective starting with the first release of the new annual release cycle, z/OS and z/OS.e V1.6. In some cases, more than three releases may be coexistence, migration, and fallback supported, if IBM at its sole discretion chooses to provide service support for greater than three years for a release. However, any z/OS or z/OS.e release having three or fewer months of service remaining at the time of GA of a new release will not be coexistence, migration, and fallback supported.

Note: These statements represent current intention of IBM. IBM reserves the right to change or alter the Coexistence-Migration-Fallback policy in the future or to exclude certain releases beyond those stated. IBM development plans are subject to change or withdrawal without further notice. Any reliance on this statement of direction is at the relying party's sole risk and does not create any liability or obligation for IBM.

Migration forward as well as fallback should be made within the same z/OS releases supported by the coexistence policy.

The following table shows the releases that are coexistence-supported with z/OS V1.6.

Table: Coexistence-supported releases

Notes:

OS/390 V2.9 — End of service was March 2003.
OS/390 V2.10 — End of service is September 2004.
z/OS V1.1 — End of Service was March 2004.
z/OS V1.2 — End of service is October 2004.
Operating system levels beyond z/OS and z/OS.e V1.6 represent current intentions of IBM.

This consistent coexistence, migration, and fallback policy applies to release migrations for all configurations, whether they are:

Single system configurations
Individual systems within a multisystem configuration
Cases where a simultaneous IPL is used to migrate all systems in a multisystem configuration at the same time

Since each release of z/OS can normally be ordered only until the next release of z/OS becomes orderable, it is very important that you order the required z/OS release you need for migration and coexistence while still available.

For additional information on z/OS coexistence and release migration information, refer to z/OS and z/OS.e Planning for Installation (GA22-7504) at

http://www.ibm.com/servers/eserver/zseries/zose/bkserv/

For migrations inside the IBM migration and coexistence policy, IBM Global Services (IGS) has fee-based offerings that provide a PTF on demand service for toleration and coexistence maintenance based upon a customer's SMP/E Consolidated Software Inventory (CSI). With these offerings, you specify the release of z/OS, z/OS.e, or other products, or hardware (for example, 2066) to which you are migrating, and all configured toleration/coexistence maintenance for your current system (as specified by your CSI) will be delivered to you as a customized package in electronic or physical format. This is provided through the S/390^® SoftwareXcel offering, via the Service Request and Delivery (SRD) function.

IGS also provides hands-on fee-based services to assess whether a migration outside the migration and coexistence policy might be possible. For more information on the migration services that IGS provides for both inside and outside the migration and coexistence policy, contact your local IBM sales specialist.

JES coexistence, release migrations, and fallback

You can migrate to the next version of JES2 or JES3 at the same time you migrate to the rest of z/OS. In this way, you benefit directly from the new function provided by the most current JES and enable other elements and features to benefit from this level.

Fallback for z/OS is at a system level, rather than an element or feature level. Since you migrate to JES2 or JES3 at the same time you migrate to z/OS you cannot back out JES2 or JES3 separately; you can only back out the entire z/OS product.

Although you must run the level of JES that comes with z/OS, that JES can communicate with certain lower levels of JES running on other z/OS and z/OS.e systems in the same MAS or multisystem complex.

For additional information on z/OS JES release migration and coexistence, refer to z/OS and z/OS.e Planning for Installation (GA22-7504) by visiting

http://www.ibm.com/servers/eserver/zseries/zose/bkserv/

z/OS V1.6 can be installed using:

Systempac^®, a fee system replacement offering
ServerPac, an entitled system replacement offering
CBPDO, an entitled system upgrade offering.

For more information about installing z/OS, refer to z/OS and z/OS.e Planning for Installation .

SystemPac enhancements: SystemPac has been enhanced to include:

Improved tape handling and order management
Reduced data entry
Fewer installation jobs

You can find more information about SystemPac on the Web at

http://www.ibm.com/ca/custompac/

ServerPac enhancements: Internet delivery for z/OS is now available using ServerPac. (Products other than z/OS continue to be available via the Internet using CBPDO.) You can choose between tape and Internet delivery. You can also request that all components of your order be delivered electronically.

You can download ServerPac orders directly to your z/OS host or use an intermediate node (such as a workstation) to transfer your order to your z/OS system.

ServerPac has also been enhanced to include:

Improved tape handling and order management
Reduced data entry
Fewer installation jobs

Internet delivery is available for orders placed through ShopzSeries at

http://www14.software.ibm.com/Webapp/ShopzSeries/ShopzSeries.jsp

ShopzSeries is available in the United States and many other countries.

There are additional driving system requirements for Internet delivery. They are described in z/OS and z/OS.e Planning for Installation .

General availability of ServerPac Internet delivery is planned for January 10, 2005.

SMP/E enhancements: z/OS V1.6 SMP/E includes the same functions as SMP/E V3.3. SMP/E V3.3 (5655-G44) has been enhanced, with:

RECEIVE command support for assigning SOURCEID values to already-received SYSMODs
RECEIVE FROMNETWORK support of SOCKS firewalls and secure FTP operations, using the z/OS Communications Server FTP Client
Automatic use of IEBCOPY's COPYMOD function for load modules
CHECK operand support for the REJECT command
Wildcard support in the CSI Query dialog
Internet packaging enhancements in GIMZIP and GIMUNZIP, which now support VSAM and non-VSAM data sets as well as UNIX files and directories, and to allow archives to be extracted into existing data sets
A new service routine, GIMGTPKG, to transfer GIMZIP packages without using the RECEIVE FROMNETWORK command.

For additional information, refer to Software Announcement 204-176 , dated August 10, 2004.

Customized Offerings Driver: The Customized Offerings Driver (5655-M12) has been updated to support the installation of z/OS V1.6 with SMP/E V3.3, the additional driving system PTFs required to install z/OS V1.6, and electronic delivery for ServerPac. The Customized Offerings Driver is now at level V2.1.1.

Recommended Service Upgrade (RSU): IBM recommends that you use the Recommended Service Upgrade (RSU) strategy to maintain z/OS after installation. RSU is based on Consolidated Service Testing (CS), which uses customer-like workloads in a high-stress sysplex environment to verify key z/OS, WebSphere^®, DB2^®, CICS, and other functions. For more information about RSU, visit

http://www.ibm.com/servers/eserver/zseries/zos/servicetst/

Performance considerations: Additional information on z/OS V1.6 performance will be published at general availability. Contact an IBM representative at or after general availability.

User group requirements: z/OS V1.6 satisfies or partially satisfies requirements from IBM customers and one or more of the worldwide user group communities. Information on the specific User Group Requirements (numbers and descriptions) can be found at

http://www.ibm.com/servers/eserver/zseries/zos/bkserv/user_group_reqs.html

Planning information

Direct customer support: Direct customer support for questions about the installation and use of the product is provided by IBM Operational Support Services — SoftwareXcel Enterprise Edition or SoftwareXcel Basic Edition. These fee services can help enhance productivity by providing voice and electronic access into the IBM support organization. IBM Operational Support Services — SoftwareXcel Enterprise Edition or SoftwareXcel Basic Edition will help answer questions pertaining to usage, how to, and suspected software defects for eligible products.

Installation and technical support is provided by IBM Global Services. For more information on services, call 888-426-4343. To obtain information on customer eligibility and registration procedures, contact the appropriate support center.

Packaging: When ordering z/OS, IBM recommends that the customer also order all the unpriced optional (export controlled) features that may be needed in the future. That is because these features may not still be orderable later when the customer needs them. For example, to obtain stronger encryption support (security) for the z/OS Integrated Security Services Base Element, you must specify the security feature named z/OS Security Level 3.

System integrity

IBM will accept APARs where the installation of z/OS introduces an exposure to system integrity.

Security, auditability, and control

Data security and auditability in the z/OS environment are enhanced by the functions available in the optional Security Server for z/OS feature. The customer is responsible for evaluation, selection, and implementation of security features, administrative procedures, and appropriate controls in application systems and communication facilities.

Typically, when one z/OS release becomes orderable in ServerPac, SystemPac, and CBPDO, the previous release is no longer orderable. Since each release of z/OS can normally be ordered only until the next release of z/OS becomes orderable, it is very important that you order the z/OS release you need for migration and coexistence while still available.

To obtain the Web deliverables listed above, visit

http://www.ibm.com/server/eserver/zseries/zos/downloads

The end of service for a Web deliverable occurs at end of service for the release on which it runs.

New licensees

New licensees of z/OS V1.6: The z/OS product ships its executable code via Customized Offerings (CBPDO, ServerPac, SystemPac). Noncustomized items (for example, CD-ROMs, Hardcopy Publications) will continue to be shipped via the stand-alone product.

For all z/OS orders, the current customer install base of the Customized Offering 5751-CSx (not the install base of 5694-A01) must be retained to determine the z/OS version and release level most recently ordered.

Production of z/OS V1.6 orders will begin on the planned general availability date, September 24, 2004 . Ship dates for orders will be based on order sequence, Customized Offering selected, production capability, and customer-requested arrival date. Due to the amount of customization of ServerPac orders, shipments will begin approximately two weeks after general availability. Due to the amount of additional customization of SystemPac orders, shipments will begin approximately four weeks after order and data input verification. For CBPDO orders, shipments will begin one week after general availability. In all cases, no delivery commitments are to be made to the customer until confirmed arrival dates are in ESW.

Notes

The Redbooks collection is updated, concurrently, with z/OS releases.
The z/OS Security Server RACF Collection is updated, concurrently, with z/OS releases, and is available one week after the release general availability to licensees of the z/OS Security Server optional feature. The update for z/OS V1.6 is planned to be available October 1, 2004.
The feature descriptions listed above are the same offered in z/OS V1.5.
When the above softcopy collections are ordered as features of z/OS V1.6, the special subscription price includes automatic shipment of all updates made while the product version can be ordered.

The z/OS Software Products Collection includes over 1,645 unlicensed online documents for more than 265 z/OS software products and Parallel Sysplex, and a softcopy tools disc. This collection includes documents for multiple releases of software products that run on z/OS. The documents are provided in BookManager format and, when available, in PDF format as well.

The IBM eServer zSeries Redbooks Collection contains IBM Redbooks, in PDF format, related to z/OS and other zSeries products. IBM Redbooks, which are produced by the International Technical Support Organization, include timely technical information based on realistic scenarios and are created by IBM experts, customers, and business partners from around the world.

The IBM Redbooks are also available for viewing or downloading on the following Web site

http://www.ibm.com/redbooks/

To find Redbooks that apply to z/OS, enter z/OS in the search field at the top of the Web page.

The z/OS Security Server RACF Collection includes unlicensed softcopy documents, in BookManager format, for numerous software product libraries that reference z/OS Security Server RACF. It also includes education course listings, Web sites to access sample code on the Internet, and Portable Document Format (PDF) files for the z/OS Security Server manuals, as well as softcopy tools. Using this collection, the customer has easy access to all the Security Server RACF-related information without handling individual sets of documents and libraries on many CD-ROMs.

The z/OS Version 1 Release 6 and Software Products DVD Collection (SK3T-4271) includes softcopy tools, libraries for z/OS Version 1 Release 6 (the element and feature libraries), the libraries for multiple releases of z/OS software products, and selected IBM eServer zSeries Redbooks. Both BookManager and PDF formats, when available, are included on this single DVD. This comprehensive z/OS collection is essentially the z/OS Version 1 Release 6 Collection (SK3T-4269) and the z/OS Software Products Collection (SK3T-4270) combined with selected IBM Redbooks from the IBM eServer zSeries Redbooks Collection (SK3T-7876) and delivered on the higher-density DVD technology. The contents of the popular zFavorites for zSeries mini-CD is also included on the DVD collection. This collection requires a DVD drive that can read discs in DVD-9 (single-sided, dual-layer) format.

Optional licensed publications: There are no optional licensed hardcopy or softcopy publications available for ordering by feature numbers to include in the product package shipment. However, z/OS licensed publications are offered in softcopy format on a CD-ROM, which can be ordered separately from the product package, and on the Internet.

Licensed users can obtain the licensed documents for z/OS by purchasing the z/OS Licensed Product Library collection (LK3T-4307) using the normal IBM publications ordering methods. Users can also access the licensed documents free of charge on the Internet using the IBM Resource Link™ Web site. Access to these documents on IBM Resource Link requires a key code and an IBM Resource Link Web user ID and password. Information concerning the key code for the licensed publications is now available in the installation guide that is delivered with the ServerPac or SystemPac deliverable or in the Memo to User Extension (MTUX) with CBPDO. Information about ordering the licensed softcopy collection and accessing IBM Resource Link is provided on the following Web site

http://www.ibm.com/servers/eserver/zseries/zos/bkserv/resource_link.html
