Overview
Bottom rule

Enterprises are transforming their businesses to access and synthesize data to more effectively compete in today's economy. Companies are creating new solutions to capture value from data in real time to serve their mobile stakeholders, while requiring the highest levels of security and resiliency. Companies are also changing the way they assimilate, process, and deliver information to maximize value from information. To meet these needs, an enterprise must harvest huge volumes of data to extract and deliver business insight from raw data and perform "information gymnastics" to uncover and act quickly on competitive advantages. These insights, based on rapid and effective transformation of data, can be used to enable informed decision making on everything from product pipelines to next best actions at points of sale.

The computing environment typically needed for this processing comprises a scalable infrastructure that must be highly secured and accessible on demand, to serve a global market. The environment must be prepared to meet audit and regulatory requirements rendered even more complex in today's borderless economy. Mobile and social computing are the new norms for customer engagement and have created unprecedented requirements for availability, speed, and security.

Throughout the journey to the new digital enterprise, companies must also support exceptional qualities of service while using innovative mobile applications to mine data or capture data to surface new business opportunities. This demand for agility, framed against a backdrop of stringent business requirements, calls for a platform armed with autonomics to drive innovation while minimizing risk. It also requires a platform that is much easier to use. z/OS V2.2 can help you take full advantage of this new transformational opportunity with a scalable, highly available, and trusted infrastructure. In addition, some aspects of z/OS administration have been dramatically simplified with the inclusion of an updated z/OSMF to help you improve process quality, simplify management, and automate work.

Together, the IBM z/OS V2.2 operating system and the z13 server deliver innovations designed to help you build the next-generation infrastructure you need to power your new workloads.

Availability

Availability is a cornerstone for the z platform, and z/OS continues to make strides in finding and reducing opportunities for downtime.

z/OS Workload Manager (WLM) provides routing recommendations for Parallel Sysplex workload balancers such as the Communications Server Sysplex Distributor based on a number of factors, including application server health. An extended z/OS V2.2 WLM Health service is designed to accept server health adjustments from other authorized participants in a Parallel Sysplex. Also, cross-system coupling facility (XCF) and cross-system extended services (XES) processing are designed to provide server health adjustment factors to WLM, lowering or raising the health factors as circumstances warrant. This new function is intended to help workload balancers that use WLM services to route work to servers that are working well and away from those that are not, helping improve application and Parallel Sysplex availability. z/OS Runtime Diagnostics (RTD) identifies servers having health values that fall below the maximum (100), to help you identify server health issues that might be causing system problems.

In addition, z/OS V2.2 XCF is designed to improve resiliency by delaying, and, if necessary, rejecting messages sent to group members that are not effectively processing their signals. This support is intended to better isolate XCF groups so that problems with signal delivery for one group are less likely to impact signal delivery for other groups.

z/OS V2.2 JES2 is designed to enable you to dynamically increase the JES2 checkpoint size in place if there is sufficient space to support expansion. This supplements other methods of increasing checkpoint space, such as using the checkpoint reconfiguration dialog to move the checkpoint or add another checkpoint device. Combined with the existing dynamic volume expansion capabilities of IBM System Storage® DS8000® family devices, this new function is designed to enable you to increase volume size and then expand a checkpoint data set when necessary, all without disrupting system operation.

z/OS V2.2 supports the Multi-Target Peer-to-Peer Remote Copy (MT-PPRC) capability for IBM System Storage DS8000 series with a minimum MCL, announced in Hardware Announcement ZG14-0280, dated October 6, 2014, and Hardware Announcement ZG14-0281, dated October 6, 2014.

MT-PPRC is designed to provide the capability to have two PPRC relationships on a single primary volume. With this MT-PPRC, you can add another PPRC target volume to provide additional data protection to act as a backup if failing over to one copy is not possible. HyperSwap® has been enhanced to exploit MT-PPRC. This support is designed to provide enhanced HyperSwap capabilities, enabling you to configure two HyperSwap targets, a preferred and an alternate. During an unplanned HyperSwap event, HyperSwap will attempt to swap to a preferred target and swap to an alternate target if it cannot swap to the preferred copy. This function is also available on z/OS V1.13 and z/OS V2.1 with the PTFs for APARs OA43661 and OA46683, and works with IBM Tivoli® Storage Productivity Center for Replication for System z®, V5.2 (5698-Z11), IBM Tivoli Storage Productivity Center, V5.2 (5608-PC1 or 5725-F93), and the GDPS/Multitarget Metro Mirror function of GDPS® 3.12.

z/OS V2.2 DFSMS is designed to provide new FlashCopy® function by supporting up to 12 targets for incremental FlashCopy. Incremental FlashCopy can create copies of a number of volumes more quickly and effectively than repetitive, full-volume FlashCopy operations. This new function is intended to provide more flexibility and resilience for FlashCopy, and to help you better protect application availability and provide improved data protection across physical volume failure events. This function is also available for z/OS V1.13 and z/OS V2.1 with the PTFs for APARs OA45412 and PI22256, and requires an IBM DS8870 Storage Subsystem with the appropriate licensed microcode level.

z/OS V2.2 is designed to enable LOGREC data sets to be deallocated without an IPL. An updated SETLOGRC command is intended to deallocate an in-use LOGREC data set and enable you to specify a new data set name. This can enable you to discontinue the use of a particular LOGREC data set when switching to either a log stream or a different LOGREC data set.

z/OS V2.2 supports new keywords for CFRM policy definition to enable you to specify which sites should be preferred when a structure is duplexed. This is intended to provide more control over the placement of duplexed structures; for example, you might want to specify that a structure only be duplexed within the same site or that it only be duplexed within the same site for performance reasons, or that it only be duplexed between two sites for disaster recovery reasons.

z/OS V2.2 is designed to make two improvements to subsystem initialization (SSI) processing. First, the system is designed to validate that an initialization routine specified in an IEFSSNxx parmlib member actually exists before attempting to start a subsystem. This is intended to help avoid IPLs required to recover from missing or incorrectly specified initialization routines. Second, new operands of the SETSSI command enable you to specify that a subsystem be deleted when the only alternative would be to IPL.

z/OS V2.2 IBM Tivoli Directory Server (ITDS, LDAP) supports a new transition mode for a sysplex owning LDAP server. This mode is designed to enable other LDAP servers in a Parallel Sysplex to be shut down and restarted at a new compatibility level, or with additional back ends, without shutting down all LDAP services in the sysplex. This new function is intended to help you improve the availability of applications that require LDAP services.

z/OS V2.2 Predictive Failure Analysis (PFA) is designed to monitor several ranges of private area virtual storage for multiple address spaces and to warn you when one or more of those address spaces exceeds criteria that can indicate eventual private area virtual storage exhaustion. This new function is designed to help you improve system availability by providing information you can use in advance of storage exhaustion, as long as the rate of storage consumption is not too rapid. Also, PFA provides support to enable you to specify address spaces that should be monitored for a number of checks, including the private area storage check.

z/OS V2.2 system logger provides support for preallocating offload data sets. This new function is designed to enable you to specify that offload data sets be allocated ahead of time for selected log streams. Corresponding support enables you to specify preallocation using Logger policy, a programming interface, and operator commands. Also, new messages are intended to provide a timely warning in the event that problems arise with log stream offload data set preallocation. This new function is intended to help you avoid situations in which delays in log stream offload processing cause system problems and provide more time to react should data set allocation delays occur.

z/OS V2.2 SLIP processing has been changed to enable you to specify operator console commands to be issued when the trap is matched. This new function is intended to provide a simple and flexible way to issue operator commands during problem diagnosis.

Scalability and performance

Scalability and performance are vital to supporting your growing analytics needs and supporting mobile workloads. With increasing volumes of data, z/OS further optimizes processing, moves information to optimize consumption and use, and addresses resilience needs.

I/O priority is set throughout much of the system by the I/O supervisor (IOS) and z/OS Workload Manager (WLM) components and honored by the channel subsystem and IBM System Storage DS8000 series control units. z/OS V2.2 is designed to provide additional prioritization data for the FICON fabric so that the highest priority read and write operations can be done first when the fabric becomes congested. This new function requires support available in z13 processors, an IBM DS8870 Storage Subsystem microcode level, and corresponding support in the FICON switches. This function is also planned to be available on the z/OS V2.2 general availability date for z/OS V1.13 and z/OS V2.1 with the PTFs for APARs OA47297 and OA44431. This is intended to provide end-to-end prioritization according to WLM policy for DASD I/O operations, in addition to existing support for channel and control unit prioritization. For more information about the availability of this function, refer to Hardware Announcement ZG15-0001, dated January 14, 2015.

z/OS V2.2 provides support for the new vector extension facility (SIMD) instructions available on z13 servers. This new support, also available for z/OS V2.1 with the PTFs for APARs OA43803 and PI12412, is intended to help enable high-performance analytics processing and is exploited by z/OS XML System Services; IBM 31-bit SDK for z/OS, Java™ Technology Edition, Version 8 (5655-DGG); IBM 64-bit SDK for z/OS, Java Technology Edition, Version 8 (5655-DGH); Enterprise PL/I for z/OS, V4.5 (5655-W67); and Enterprise COBOL for z/OS, V5.2 (5655-W32). WebSphere Application Server for z/OS, V8.5 (5655-W65) workloads running with Java 8 are expected to benefit from SIMD exploitation. You can find more information about Java exploitation in Software Announcement ZP15-0011, dated January 14, 2015, and Software Announcement ZP15-0004, dated January 14, 2015, about PL/I exploitation in Software Announcement ZP15-0015, dated January 14, 2015, and about COBOL exploitation in Software Announcement ZP15-0034, dated January 14, 2015.

z/OS V2.2 Global Mirror (XRC) is designed to work with z/OS Workload Manager and IBM System Storage DS8000 with the z/OS Global Mirror feature to automatically throttle low-priority write operations when they would cause significant delays that might affect response time. The system is designed to enable you to specify that appropriate delays be imposed for the write activity for different classes of work, based on their importance as defined in WLM service class definitions. This is intended to make it unnecessary to adjust write pacing settings and monitor data set residency, and improve the system's responsiveness to more important work during periods of high write activity. This function requires the appropriate licensed microcode level for IBM DS8870 Storage Subsystems and is also available for z/OS V1.13 and z/OS V2.1 with the PTFs for APARs OA41906, OA44004, and OA43453.

IBM zHyperWrite is a new technology that combines DS8000 and z/OS enhancements that deliver performance benefits for writing operations to DB2 logs in the Metro Mirror (PPRC) environment. This new technology can help reduce up to 43% of the DB2 log write time. 2 zHyperWrite requires z/OS V2.1 with the PTF for APAR OA44973 or z/OS V2.2, either DB2 10 (5605-DB2) or DB2 11 (5615-DB2) with the PTF for PI25747, and an IBM DS8870 Storage System with a minimum microcode level. zHyperWrite also requires IBM GDPS or IBM Tivoli Storage Productivity Center for Replication HyperSwap technology. This facility is expected to provide improved DB2 transactional response time and log throughput improvements.

2
Performance improvements are based on internal IBM laboratory tests. Your results will vary.

zEnterprise Data Compression (zEDC) for z/OS, running on z13, IBM zEnterprise EC12 (zEC12), and IBM zEnterprise BC12 (zBC12) servers with the zEDC Express® adapter is designed to support low-latency data compression and inflation functions. In addition to existing support for SMF and Extended Format BSAM and QSAM data, z/OS V2.2 DFSMSdss and DFSMShsm are designed to exploit this capability for dumping and restoring data and when DFSMShsm uses DFSMSdss to move data. This is intended to provide efficient compression with lower CPU overheads than the processor-based and software-based compression methods already available when moving data to disk storage. Together, these functions can help you save disk space, improve effective channel and network bandwidth without incurring significant CPU overhead, and improve the efficiency of cross-platform data exchange. These capabilities are also available on z/OS V2.1 with the PTF for APAR OA42243.

z/OS V2.2 Library Lookaside (LLA) is designed to make it more likely that certain program objects, such as those compiled using COBOL Version 5 (5655-W32), can be cached by LLA in VLF. This is intended to help to improve performance for users of such program objects when they are contained within libraries managed by LLA. This support is also available for z/OS V1.13 and z/OS V2.1 with the PTF for APAR OA45127.

z/OS V2.2 XML System Services uses the new vector (SIMD) instructions available on z13 processors. This function, also available on z/OS V2.1 with the PTF for APAR OA44545, is intended to help improve the performance for nonvalidating XML parsing for some documents.

z/OS V2.2 DFSMSdfp VSAM record-level sharing (RLS) processing is designed to use a control area (CA) level lock rather than a data set level lock for operations that affect only a single CA. This is intended to reduce contention and improve performance for many frequently updated VSAM key-sequenced and variable-length relative record (KSDS and VRRDS) data sets.

z/OS V2.2 DFSORT provides support for high-performance FICON (zHPF), when available, for SORTIN, SORTOUT, and OUTFIL data sets. Taking advantage of the higher start rates and bandwidth available with zHPF is expected to provide significant performance benefits on systems where zHPF is available.

z/OS V2.2 JES2 is designed to support a maximum of one million (1,000,000) active jobs, a substantial increase over the prior maximum of 400,000. This is intended to enable more jobs to be stored on the spool at a time, which, in turn, can enable you to run more work over shorter periods and increase spool retention time.

z/OS V2.2 is designed to support up to four subchannel sets on z13 servers. This helps relieve subchannel constraints and can enable you to define larger I/O configurations that support multi-target Metro Mirror (PPRC) along with large numbers of PPRC secondaries and Parallel Access Volume (PAV) aliases. As with the prior support for up to three subchannel sets, you can define base devices, aliases, and secondaries in the first subchannel set (set zero), and define aliases and secondaries in the other subchannel sets. All four subchannel sets support FICON and zHPF protocols. This support is also available on z/OS V1.13 and z/OS V2.1 with the PTF for APAR OA43495.

A number of improvements for z/OS V2.2 zFS are designed to provide significant performance improvements for directory update processing. Also, the zFS kernel supports 64-bit addressing (AMODE64), enabling you to use much larger data and object caches, and to support running zFS in the z/OS UNIX™ (OMVS) address space, which is expected to yield further performance gains for all workloads using zFS file systems.

z/OS V2.2 UNIX System Services is designed to support a substantially increased number of threads. The current limit on the number of threads that can run in the kernel is approximately 32,000. The new expected limit is approximately 10 times the current limit. The actual limit for a particular system or set of applications will depend on the services used and the additional storage those services require.

z/OS V2.2 is designed to support up to 4 TB of real memory in a single LPAR on z13 processors. This is intended to help support more workload per z/OS image and more memory-intensive applications. As an example, large amounts of memory in z/OS and in the coupling facility can be used to increase the size of DB2 local and group buffer pools, keeping larger amounts of data resident in memory and achieving benefits in terms of CPU usage, I/O reduction, and improved response times. This support is also planned to be available for z/OS V2.1 with the PTF for APAR OA47439 at z/OS V2.2 general availability.

Generation data groups (GDGs) are limited to 255 or fewer generations. z/OS V2.2 is designed to support a new type of generation data group, GDGE. When the use of GDGEs has been enabled in an IGGCATxx member of parmlib, you can specify that up to 999 generation data sets be kept concurrently. This new support for a larger number of generations is intended to make it easier to manage data sets that are created frequently. For example, it is possible to specify that all of the generations created every day for a full year be kept. Additionally, IDCAMS and DFSMSdfp processing is enhanced to enable you to specify that unexpired generation data sets be deleted automatically when retaining them would prevent the creation of a new generation.

The z/OS V2.2 NFS Server is designed to help improve performance for many operations, with a number of streamlined functions. These include designs intended to improve performance, with support for server callback, a cache processing enhancement, z/OS UNIX uid and gid caching, and support for persistent file handles.

Security

z/OS continues to provide enhancements to security capabilities to strengthen your security profile, simplify operations, and help you mitigate risk. Further enhancements address audit and compliance needs, which become more complex in today's mobile enterprise.

First issued in 1973, IBM's MVS™ System Integrity Statement, and subsequent statements for OS/390® and z/OS, has stood for over three decades as a symbol of IBM's confidence in and commitment to the z/OS operating system.

IBM's commitment includes design and development practices intended to prevent unauthorized application programs, subsystems, and users from bypassing z/OS security, that is, to prevent them from gaining access, circumventing, disabling, altering, or obtaining control of key z/OS system processes and resources unless allowed by the installation. Specifically, z/OS System Integrity is defined as the inability of any program not authorized by a mechanism under the installation's control to circumvent or disable store or fetch protection, access a resource protected by the z/OS Security Server (RACF), or obtain control in an authorized state; that is, in supervisor state, with a protection key less than eight (8), or Authorized Program Facility (APF) authorized. In the event that an IBM System Integrity problem is reported to IBM, IBM will always take action to resolve it in the specified operating environment for releases that have not reached their announced end of support dates. 3

IBM's long-term commitment to system integrity is unique in the industry 4 and forms the basis of z/OS industry leadership in system security. z/OS is designed to help you protect your system, data, transactions, and applications from accidental or malicious modification. This is one of the many reasons IBM z Systems remains the industry's premier data server for mission-critical workloads.

z/OS V2.2 is designed to provide digital signatures for SMF records written to log streams. This new function signs blocks of SMF records and chains the blocks' signatures. A signature verification function is designed to help you determine whether SMF records or blocks of SMF records have been altered or removed. This function, which requires the CP Assist For Cryptographic Function (CPACF) feature of a z Systems processor, is intended to help you detect unauthorized alterations to recorded SMF data and provide a more trusted repository for the auditing records created by a number of z/OS system components, including RACF.

These RACF enhancements are available for z/OS V2.2:

  • The RACF AUDITOR attribute, when assigned to a user ID, enables a number of RACF commands to be used with options that change the events for which SMF records are written for auditing purposes. In z/OS V2.2, RACF is designed to support a new attribute, ROAUDIT. This attribute, like the AUDITOR attribute, is intended to enable an auditor to list the contents of RACF profiles. However, ROAUDIT is designed not to allow auditors to make changes to RACF auditing options. This is intended to help you provide a better separation of duties between RACF administrators and RACF auditors.
  • RACF is designed to provide better protection for offline attacks against encrypted passwords by enabling you to use stronger encryption. Also, this support can enable you to accept additional special characters within passwords, define users enabled to use only password phrases, clean up a user's password history, and set an "expired" status for a user's password without changing it to a new value. This support is also available in z/OS V1.13 and z/OS V2.1 with the PTF for APAR OA43999. Additionally, z/OS V2.2 RACF is designed not to set default passwords when new users are defined, to remove the need for an exit (ICHDEX01) to use password encryption, and to enable the use of a password phrase with the RACLINK DEFINE command.
  • The RACF remote sharing facility (RRSF) now supports three new functions. The first is designed to enable you to change the MAIN system in a multisystem node dynamically. This new function is expected to make the overall process of changing MAIN systems much simpler. Also, RRSF is designed to enable you to specify that inbound updates from specific systems be ignored. This function is intended to enable you to have RRSF propagate updates from production systems to test systems without enabling privileged users on test systems to obtain more privileges on production systems. Finally, a new function in the R_admin callable service and in the IRRXUTIL REXX language interface is designed to return RRSF configuration and operational information.
  • Certificates can be used for a number of different services. z/OS V2.2 RACF is designed to enable you to use more granular certificate administration, supporting narrowed spans of administrative control using new profiles in the RDATALIB class.

z/OS V2.2 SAF and RACF provide two new functions for users of z/OS UNIX System Services. The first is designed to enable a user with access to a new profile in the UNIXPRIV class to perform additional file system-related operations, such as listing files in a directory, without being authorized to alter the files. The second is designed to enable security administrators to prevent programs from being run from designated file systems. These changes are both intended to help you improve z/OS UNIX security.

In z/OS V2.2, a number of new security health checks are available. They are designed to determine whether recommended controls over ICSF, z/OS UNIX System Services, and RACF remote sharing facility (RRSF) resources exist, and to determine whether recommended password controls and encryption techniques are in use. These checks are intended to help you improve system security.

z/OS V2.2 includes new function that can help you audit changes to the APF authorized library list. z/OS is now designed to write new SMF Type 90 subtype 37 records when SET PROG and SETPROG commands or the CSVAPF programming service are used to add data sets to, or remove data sets from, the current APF list.

z/OS V2.2 provides two console security enhancements. First, the system is designed to enable you to specify timeout values for MCS, SMCS, and HMCS consoles and to automatically log off users from those consoles when the timeout intervals are exceeded without any operator input. Second, a new optional SAF profile is intended to enable you to specify that a user be allowed to log on to multiple consoles concurrently. These functions are intended to help you improve console security.

As with other operator commands, the DFSMSdfp MODIFY CATALOG command can be protected using RACF profiles in the OPERCMDS class. In z/OS V2.2, a new optional OPERCMDS profile can be used by the system to determine whether a specific user is authorized to issue MODIFY CATALOG commands that alter the behavior of the system or to issue only MODIFY CATALOG commands that display information about catalog processing. This is intended to provide more granular security and better operational flexibility.

z/OS V2.2 PKI Services is designed to provide support for:

  • Requiring multiple administrators to approve the creation of new certificates. This optional multiple approver process is intended to help you prevent the creation of unauthorized certificates.
  • Online certificate status protocol (OCSP) responses to be signed with the client-specified signing algorithm as documented by RFC 6277. This is intended to improve the interoperability of PKI Services and OCSP clients.
  • Using the SHA-224 and SHA-256 with DSA encryption algorithms for signing certificates, CRLs, OCSP responses, and verify certificate requests.
  • Callers running in 64-bit addressing mode.

z/OS V2.2 System SSL is now designed to provide:

  • Support for the online certificate status protocol (OCSP) to retrieve certificate revocation status and certificate revocation lists (CRLs) over HTTP. The OCSP support is designed to retrieve revocation status information for x.509 certificates as described by RFC 2560, and the HTTP CRL support is intended to enable you to specify that System SSL should retrieve CRL information using HTTP as described by RFCs 3280 and 5280. These functions are intended to supplement the existing LDAP CRL processing and help you ensure that valid certificates are used to complete SSL and TLS secure connections. Also, z/OS V2.2 Communications Server supports these functions for application-transparent transport layer security (AT-TLS), to enable their use for applications and middleware.
  • Support for PKCS #12 certificate files. This support is designed to enable applications to specify a PKCS #12 file to be used for secure connections within an SSL environment. PKCS #12 certificate key store files can contain multiple certificate authority (CA) and end entity certificates, and more than one certificate chain. This is intended to provide better interoperation for applications that create PKCS #12 key store files, such as Java-based applications. This support is also available for z/OS V1.13 and z/OS V2.1 with the PTF for APAR OA45216.
  • Support to take advantage of the secure key support when coprocessors are configured in EP11 mode is available with Crypto Express4S (CEX4S) cryptographic features available for zEnterprise EC12 (zEC12) and zEnterprise BC12 (zBC12), and the Crypto Express5S (CEX5S) cryptographic features available for IBM z13 processors by supporting the use of secure DSA keys for signing data and for fixed Elliptic Curve Diffie-Hellman (ECDH) key exchanges.
  • Support enabling SSL sessions to be reused across different TCP ports. Also, Communications Server provides FTP support to enable new data connections to reuse associated SSL sessions for better compatibility and performance with certain FTP servers and clients. This enhancement, available for System SSL users and for both AT-TLS and native SSL users of FTP, is intended to provide both improved security and performance.

The z/OS V2.2 Network Authentication Service (NAS) is designed to support the use of X.509 certificates for Kerberos-based authentication as described by RFC 4556. This is intended to help make it unnecessary for end users to manage strong passwords for some applications. Also, NAS is now designed to allow you to run the Key Distribution Center's (KDC's) started task without assigning the user ID under which it runs UID(0), which can help you minimize the use of UID(0).

z/OS V2.2 BCPii is designed to write new SMF Type 106 records for HWISET and HWICMD events. This enhancement is intended to enable you to audit operations such as updates to attribute values for CPC processor weights, image profiles, and activation profiles; and, for operations affecting a CPC or image such as image activations.

Standards

z/OS Version 2 is designed to continue to meet a number of important standards. In addition to maintaining previously announced support in z/OS Version 1 for a number of industry standards such as RFCs and PCI-DSS, and adding support for a number of additional standards in z/OS V2.1, these include:

  • z/OS Version 1 earned the IPv6 Phase 2 Ready logo and USGv6 Profile Version 1.0 (NIST SP500-267) certification. z/OS V2.2 Communications Server is designed to meet these standards.
  • The programming interfaces provided by z/OS V2.1 Unicode Services are designed to meet the Unicode 6.0 standard.
  • IBM z/OS V2.1 has been certified as meeting the requirements of the German Common Criteria Certification Body (BSI) Operating System Protection Profile (OSPP) at EAL 4+.
  • IBM plans to pursue an evaluation to the Federal Information Processing Standard (FIPS) 140-2 using National Institute of Standards and Technology's (NIST) Cryptographic Module Validation Program (CMVP) for the System SSL component of the Cryptographic Services element of z/OS. The scope of this evaluation will include algorithms provided by the CP Assist for Cryptographic Functions (CPACF) that are utilized by System SSL. This is intended to help satisfy the need for FIPS 140-2 validated cryptographic functions when using z/OS Communications Server capabilities such as AT-TLS and protocols such as TN3270 and FTP when secured using AT-TLS.
  • IBM also plans to pursue an evaluation to the Federal Information Processing Standard (FIPS) 140-2 using National Institute of Standards and Technology's (NIST) Cryptographic Module Validation Program (CMVP) for the ICSF component of the Cryptographic Services element of z/OS. The scope of this evaluation is planned to include algorithms provided by the CP Assist for Cryptographic Functions (CPACF) and utilize the Crypto Express® coprocessors configured as accelerators and Enterprise PKCS #11 coprocessors. This is intended to help satisfy the need for FIPS 140-2 validated cryptographic functions by various IBM software products and customer applications running on z/OS.

IBM plans to further extend the capabilities of the Configuration Assistant for z/OS Communications Server, a plug-in for z/OSMF, in z/OS V2.2. Additional planned enhancements will be designed to support making dynamic configuration changes to an active TCP/IP configuration, and a function designed to import existing TCP/IP profile data.

IBM intends to deliver a number of additional enhancements to SDSF in the future. These functions are planned to include new commands that will be designed to:

  • Help you perform address space level diagnosis, with display support for active task control blocks (TCBs), contents directory entries (CDEs), allocated data sets, and enqueue (ENQ) serialization conflicts
  • Display a virtual storage map and common storage utilization, including orphaned common storage
  • Display information about catalogs, mounted z/OS UNIX™ file system data sets, and SMF (SYS1.MAN) data sets
  • Show ASID-related virtual storage information, including allocated storage by subpool
  • Provide information about real, virtual, and auxiliary storage consumption by ASID
  • Display information about active subsystems, and identify a number of IBM subsystems such as DB2 and WebSphere MQ
Additional SDSF displays will be intended to provide:
  • SMS-related information, including active classes and the volumes in storage groups
  • Parallel Sysplex information about XCF structures, groups, and group members
  • WLM-related information, including service and reporting classes
  • Support for browsing virtual memory contents for a specified address space
  • Generic tracker information
Finally, SDSF is planned to provide a new facility that will be designed to help you manage dynamic exits, which will be intended to make it easier to display active exits and to manage activation, deactivation, and replacement of system exits.

z/OS V2.2 is planned to be the last release to include the Trivial File Transfer Protocol Daemon (TFTPD) function in z/OS Communications Server.

z/OS V2.2 is planned to be the last release to include the TCP/IP legacy device drivers for FDDI and Token Ring (LCS with LINKs FDDI and IBMTR), Token Ring (MPCIPA with LINK IPAQTR), and ENet and FDDI (MPCOSA with LINKs OSAENET and OSAFDDI). If you are using any of these devices, IBM recommends you migrate to newer devices such as OSA Express QDIO and Hipersockets. Note that this withdrawal is only for TCP/IP device types, and not for any of the SNA device drivers.

z/OS V2.2 is planned to be the last release to provide support in the Common Information Model (CIM) component for the Java™ Managed Provider Interface (JMPI).

z/OS V2.2 is planned to be the last release to support the DFSMSrmm CIM Provider.

z/OS V2.2 is planned to be the last release to include a number of TSO/E-based System Data Mover (SDM) related commands. Except for the query commands (CQUERY, FCQUERY, RQUERY, XQUERY, XSTATUS), and the XSET command, which will remain, IBM recommends you use the REXX version of these commands instead. For more information about using the REXX commands, see z/OS DFSMS Advanced Copy Services.

As previously announced in Hardware Announcement ZG14-0009, dated February 24, 2014, the Simple Mail Transport Protocol Network Job Entry (SMTPD NJE) Mail Gateway and Sendmail mail transports are planned to be removed from z/OS. IBM now plans for z/OS V2.2 to be the last release to include these functions. If you use the SMTPD NJE Gateway to send mail, IBM recommends you use the existing CSSMTP SMTP NJE Mail Gateway instead. In that same announcement, IBM announced plans to provide a replacement program for the Sendmail client that would not require programming changes. Those plans have changed, and IBM now plans to provide a compatible subset of functions for Sendmail in the replacement program and to announce those functions in the future. Programming changes or alternative solutions to currently provided Sendmail functions might be required. No replacement function is planned in z/OS Communications Server to support using SMTPD or Sendmail as a (SMTP) server for receiving mail for delivery to local TSO/E or z/OS UNIX System Services user mailboxes, or for forwarding mail to other destinations.

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 V2R2 Planning for Installation (GA32-0890) for a listing of specific software requirements at

http://www.ibm.com/systems/z/os/zos/library/bkserv/index.html

Compatibility

Coexistence, release migration, and fallback

z/OS gives you compatibility and flexibility as you migrate systems in a multisystem configuration by allowing multiple releases of z/OS 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.


Note: These statements represent the 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.

IBM provides the following coexistence, migration, and fallback for z/OS V2.2:

IBM plans to support an n-2 approach, where three consecutive releases are planned to be supported for coexistence, fallback, and migration. For example, where "n" is z/OS V2.2, IBM intends to allow you to upgrade from z/OS V1.13 directly to z/OS V2.2 with full coexistence, migration, and fallback support to maximize the value of your investment, and from z/OS V2.1 to z/OS V2.2 with full coexistence, migration, and fallback support.

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

Table: Coexistence-Migration-Fallback for z/OS V2.2

Release Coexistence-Migration-Fallback supported with release in Column 1
z/OS V1.13 z/OS V1.11, 7 z/OS V1.12, 8 z/OS V1.13 9
z/OS V2.1 z/OS V1.12, 8 z/OS V1.13, 9 z/OS V2.1
z/OS V2.2 z/OS V1.13, 9 z/OS V2.1, z/OS V2.2
7
z/OS V1.11 end of service was September 30, 2012.
8
z/OS V1.12 end of service was September 30, 2014.
9
z/OS V1.13 end of service is planned to be September 30, 2016.

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

License Metric Change

  • z/OS V2 is only offered with NALC pricing for customers using NALC for z/OS, V1 who are using PSLC for their middleware programs. z/OS V2 customers using AWLC or WLC or AEWLC or EWLC pricing for their middleware programs must migrate from NALC to zNALC pricing.
  • All z/OS customers using NALC pricing are encouraged to migrate to zNALC pricing to obtain the zNALC advantages such as sub-capacity pricing for z/OS with zNALC supported by the SCRT reports, lower prices above 45 MSUs, and aggregated pricing across qualified Parallel Sysplexes.

See Software Announcement ZA07-0102, dated January 9, 2007 (IBM System z® New Application License Charges) and Software withdrawal ZP07-0510, dated December 4, 2007 (Software withdrawal: Selected IBM System z products -- Some replacements available).

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.

z Systems New Application License Charge (zNALC) ordering information

z/OS (and z/OS priced features) is the only program eligible for zNALC charges. In the IBM enterprise software billing and fulfillment system, IBM uses the term basic license to indicate licenses that are billable. When software is licensed to a stand-alone server, IBM places basic (billable) licenses on that stand-alone server. When software is licensed to multiple machines in a qualified Parallel Sysplex, IBM places basic (billable) licenses on an entity representing the Sysplex and places registration (no-charge) licenses on each licensed machine belonging to the Parallel Sysplex.

z/OS with zNALC charges can aggregate across servers that participate in a fully qualified Parallel Sysplex. For more information on Parallel Sysplex, visit

http://ibm.com/zseries/swprice/sysplex
In the case that there are multiple servers with z/OS with zNALC charges participating in qualified Parallel Sysplex and you request aggregated pricing, then IBM will apply the zNALC basic license structure to the Sysplex and apply zNALC no-charge registration licenses to each of the individual servers that comprise the Sysplex.

Statement of good security practices
Bottom rule

IT system security involves protecting systems and information through prevention, detection, and response to improper access from within and outside your enterprise. Improper access can result in information being altered, destroyed, or misappropriated or can result in misuse of your systems to attack others. Without a comprehensive approach to security, no IT system or product should be considered completely secure and no single product or security measure can be completely effective in preventing improper access. IBM systems and products are designed to be part of a comprehensive security approach, which will necessarily involve additional operational procedures, and may require other systems, products, or services to be most effective. IBM does not warrant that systems and products are immune from the malicious or illegal conduct of any party.

Sub-capacity charges for VWLC products

Sub-capacity charges for VWLC products are based on product LPAR utilization capacity. Product LPAR utilization capacity for a VWLC product is the highest number of MSUs utilized by the combined LPARs in which a VWLC product runs concurrently during a reporting period. The number of MSUs is based on the highest observed rolling 4-hour average utilization used by the combination of the relevant LPARs during the reporting period.

Sub-capacity charges terms and conditions

System z software charges at less than full machine capacity for eligible VWLC products apply when z/OS is running in z/Architecture® (64-bit) mode on an IBM System z 900, no other MVS-based operating system is licensed to that server, and the required information is provided by the customer in accordance with the applicable terms.

Sub-capacity charges for a VWLC product is based on the utilization of the LPARs where/when the product executes. To obtain charges at less than full machine capacity for VWLC products, the customer is required to:

  • Sign and abide by the terms of the Attachment for IBM System z Workload License Charges - (Z125-6516).
  • Obtain the latest version of the Sub-Capacity Reporting Tool.
  • Install any VWLC product and IBM e(logo)server System z 900 Licensed Internal Code (LIC) service required for sub-capacity charging. Required service will be listed on the WLC Website
    http://www.ibm.com/zseries/swprice
  • Collect SMF data as required by the Sub-Capacity Reporting Tool. Retain the collected SMF data for a period of not less than six months.
  • Use the IBM provided Sub-Capacity Reporting Tool to process the collected SMF data. The Sub-Capacity Report produced by the tool is used to determine required license capacity for the VWLC products. Required license capacity is determined based on the largest MSU value of a VWLC product running concurrently in all LPARs during the reporting period. IBM reserves the right to request the system data that supports these product-defined capacity values for a period of up to six months after the data was collected.
  • Provide an initial Sub-Capacity Report to begin to receive the benefits of less than full machine capacity charges. Sub-capacity charging will follow submission of a Sub-Capacity Report. There will be no retroactive application of sub-capacity charges.
  • Submit Sub-Capacity Reports monthly.
  • Submit Sub-Capacity Reports for all VWLC products with complete data for the entire reporting period to the email address and by the date specified in the current IBM System z Workload License Charges Exhibit (Z125-6324) and on the System z Software Pricing Website
    http://www.ibm.com/zseries/swprice

    Sub-Capacity Reports that reflect a changed product defined capacity will be considered to be orders placed by the customer without further action on the customer's part, and IBM is authorized to make any resulting billing increase or decrease. To place an order for a new license or to discontinue licenses, move licenses between machines, report a hardware model upgrade, or enable or disable product features, the customer must contact IBM or their IBM Business Partner.

  • Configure the machine to send weekly Transmit System Availability Data (TSAD) to IBM via the IBM System z 900 Remote Support Facility (RSF). If the machine cannot connect via the RSF, provide this TSAD via an alternate means documented in the z/OS publication Planning for Workload License Charges at
