Description
Bottom rule

z/VSE V4.3 shows z/VSE's commitment and dedication to clients' needs.

z/VSE V4.3 is designed to:

  • Help clients protect their existing investment in z/VSE
  • Address requirements for growing z/VSE workloads
  • Allow consolidation of z/VSE systems
  • Offer the value of the latest IBM System z10 and IBM System Storage technology
  • Provide ease of use for configuration of mixed IT environments

z/VSE V4.3 continues the z/VSE focus on scalability, security, service-oriented architecture (SOA), and hybrid solutions that exploit z/VSE and Linux on System z. Hybrid solutions may run on z/VM's state-of-the-art virtualization technology and may benefit from the dynamic capabilities of the latest IBM System z10 technology.

Enhancements planned for z/VSE V4.3 include:

  • Virtual storage constraint relief:

    z/VSE V4.3 will fulfill several customer requirements and move selected system programs and buffers from 24-bit into 31-bit storage. This will allow customers with growing workloads (for example CICS) and/or those who want to consolidate their VSE systems to satisfy their increased 24-bit storage needs. Among the areas that will be addressed are VSE/VSAM, DL/I, and the z/VSE supervisor.

  • Ease-of-use configuration and infrastructure simplification:

    Support of four-digit device addresses gives clients more flexibility and allows for advanced planning. Customers are no longer required to provide a z/VSE specific configuration. This is specifically helpful in mixed IT environments where customers may run z/VSE together with other IBM System z operating systems (z/VM, Linux on System z, and/or z/OS). To provide transparency for system, vendor, and user applications that rely on three-digit device numbers, z/VSE V4.3 will map a four-digit device number to a three-digit one. After Initial Program Load, only the three-digit device address will be used.

  • Exploitation of innovative IBM System z10 technology:
    • Ability to dynamically add logical CPs without preplanning:

      IBM System z10 allows users to dynamically change logical processor definitions for a logical partition (LPAR) without requiring the LPAR to be deactivated and reactivated. z/VSE V4.3 is designed to exploit this feature and to allow adding central processors (CPs) dynamically without re-IPL of the z/VSE system. This allows clients to increase the capacity of the z/VSE V4.3 system dependent on workload needs. Preplanning requirements and the need for planned outages are reduced. Once a CP is no longer needed, z/VSE V4.3 allows you to remove it from the online configuration of the LPAR, so that it no longer consumes LPAR CP share. The support is not available in a z/VM guest environment.

    • Large page (1 megabyte page) support:

      The z10 large page support allows backing of MB pages in virtual storage with MB pages in processor storage. z/VSE V4.3 is designed to exploit large pages for data spaces. Long-running applications accessing data spaces frequently may benefit from improved CPU utilization. Large page support for data spaces can help customers to even better exploit large processor storage. z/VSE V4.3 is designed to implement the support transparently for applications. The support is not available in a z/VM guest environment.

    • FICON Express8:

      FICON Express8 is exclusive to IBM System z10. It is designed to provide faster access to data with a link rate of 8 gigabits per second (Gbps) and the ability to auto-negotiate to 2 or 4 Gbps. z/VSE V4.1 and later supports FICON Express8 in two modes of operation:

      • CHPID TYPE FC - when utilizing native FICON or Channel-To-Channel (CTC)
      • CHPID TYPE FCP - for support of SCSI disks

      The support of FICON Express8 is expected to be transparent to applications.

      For details refer to Hardware Announcement 109-417, dated July 21, 2009.

  • Enhanced storage options:
    • Parallel Access Volume (PAV) feature of IBM System Storage DS8000 and DS6000 series:

      The Parallel Access Volume (PAV) feature of the DS8000 and DS6000 series allows accessing an ECKD-type volume with multiple concurrent requests. With PAV support, applications may benefit from a performance improvement when using I/O processing in different VSE tasks. The support is also available on z/VSE V4.2 with PTFs.

    • IBM System Storage DS8000 Remote Mirror and Copy (RMC) feature:

      The RMC feature is a licensed feature of the DS8000 and is supported in z/VSE through the ICKDSF component. The support is also available with z/VSE 4.1 and later with PTFs.

    • IBM System Storage TS7700 Virtualization Engine Release 1.5 including TS7720 disk-only virtual tape systems:
      • TS7700 Release 1.5 is supported by z/VSE V4.1 and later. z/VSE supports the TS7700 as a standalone system in transparency mode. COPY EXPORT is not supported.
      • z/VM DFSMS/VM™ provides services that enable a z/VSE guest to manage resources of the TS7720 with the PTF for APAR VM64660.
  • Security enhancements:

    Basic Security Manager (BSM) will provide security for WebSphere® MQ for z/VSE V3 to protect MQ resources using MQ resource classes. With z/VSE V4.3, BSM will include DTSECTAB resources into the SMF logging and reporting.

  • Networking enhancements:

    z/VSE V4.3 systems running in a z/VM guest environment can now benefit from the z/VM Queue I/O (QIO) performance assist for real networking devices. z/VSE V4.3 exploits this performance assist for OSA Express adapters (CHPID type OSD) and HiperSockets™ (CHPID type IQD).

  • System management enhancements:

    SNMP (Simple Network Management Protocol) is a widely used standard network protocol that allows systems to monitor elements of a network. z/VSE V4.3 will provide a monitoring agent that allows SNMP version 1 clients to retrieve z/VSE specific system and performance data. This will help performance monitors to collect data that can be used for planning purposes.

  • DOS/VS RPG II support for CICS TS:

    DOS/VS RPG II compiler support will be added to allow RPG programs implemented for CICS/VSE to run with CICS TS. Customers who stayed with CICS/VSE because of RPG can now migrate to CICS TS. DOS/VS RPG II support will also be made available with z/VSE 4.2.

  • DL/I V1.12:

    z/VSE V4.3 will deliver the new DL/I release, which will provide 24-bit virtual storage constraint relief for the CICS TS environment.

    DL/I V1.10 was required to run with CICS/VSE V2.3. With z/VSE V4.3, it will no longer be delivered. This fulfills the statement of direction in Software Announcement 207-228, dated October 09, 2007.

Migration from CICS/VSE V2.3 to CICS TS on z/VSE V4.2:

  • z/VSE V4.3 will no longer offer CICS/VSE V2.3 as part of the z/VSE V4.3 base and thus fulfills the statement of direction in Software Announcement 207-228, dated October 09, 2007.
  • Recent improvements, including BSM security enhancements in z/VSE V3, additional VSE tasks, and DOS/VS RPG II support for CICS TS in z/VSE V4.2, offer customers the capability of migrating their CICS/VSE programs on z/VSE V4.2 prior to performing an upgrade to z/VSE V4.3.
  • z/VSE V4.3 will continue to reduce inhibitors to migration and CICS workload growth by providing virtual storage constraint relief.

Note: Items mentioned as being available for z/VSE V4.1 or z/VSE V4.2 may require the user to install additional PTFs.

z/VSE V4.3 supports IBM System z servers:

  • IBM System z10 Enterprise Class (z10 EC) and IBM System z10 Business Class (z10 BC)
  • IBM System z9 Enterprise Class (z9 EC) and IBM System z9 Business Class (z9 BC)
  • IBM eServer zSeries 990, 890, 900, and 800

z/VSE V4.3 is designed to exploit selected features of innovative IBM System z10 technology. z/VSE Version 4 executes in z/Architecture mode only and supports 64-bit real addressing for selected system functions. z/VSE V4.3 is not designed to support 64-bit virtual addressing. z/VSE V4.3 can run in basic mode (z900 and z800 only), in LPAR mode, or as a guest under z/VM V5.4 or later. It is the preferred follow-on product for clients with z/VSE V4.2, z/VSE V4.1, z/VSE V3, or VSE/ESA installed. You may choose to use the Fast Service Upgrade (FSU) process when migrating from z/VSE V4.2 or z/VSE V4.1.

z/VSE V4.3 offers Midrange Workload License Charge (MWLC) pricing metrics, including a sub-capacity option, for System z10 and z9 servers. The smallest z10 BC and z9 BC server capacity setting, A01, does not qualify for MWLC. Customers on the z10 BC and z9 BC capacity setting A01 will always pay zELC for all IBM monthly license charge software.

Product positioning
Bottom rule

z/VSE Version 4.3 is designed to help customers introduce competitive new IT solutions at low cost, low risk, and fast time to market.

It is essential that z/VSE clients have the option of continuing to use their core VSE solutions while at the same time adding new applications, regardless of the chosen platform. New solutions should be able to leverage and exploit existing core z/VSE applications and data.

z/VSE V4.3 will continue to adhere to the strategy of "Protect, Integrate, and Extend" - in short "PIE."

  • Protect focuses on investment protection. z/VSE clients should be able to exploit the latest IBM System z and IBM System Storage technology to enhance and grow core z/VSE environments.
  • Integrate enables seamless integration. z/VSE clients should be able to extend their core z/VSE information assets into their overall IT system and network.
  • Extend refers to adding new solutions. z/VSE clients should be able to extend their core z/VSE solutions with solutions that exploit the advanced, standards-based capabilities of any platform, especially Linux on System z.

The "PIE strategy" is fundamentally based on an open hybrid model. This hybrid model can give clients the best of both worlds: it helps them to protect their z/VSE investments as they exploit the capabilities of complementary platforms. z/VSE plus Linux on System z is a compelling combination.

Protect

z/VSE V4.3 will continue to protect core z/VSE customer investments. Timely hardware support helps enable z/VSE customers grow and exploit innovative IBM technology. This includes virtual storage constraint relief, addressing requirements of customers with growing workloads and/or those who want to consolidate their VSE systems. A new release of DL/I will relieve virtual storage constraints for the CICS TS environment.

The exploitation of the innovative IBM System z10 technology will be further extended through the capability to dynamically change logical partitions by adding central processors without preplanning, reducing the need for planned outages due to intended capacity changes.

Large page (1 megabyte) support and FICON Express8 may provide improved CPU utilization and faster access to data, while support of the z/VM Queue I/O (QIO) performance assist can benefit networking devices connected through the OSA Express adapters or network traffic via HiperSockets.

The support of the IBM System Storage DS8000 Remote Mirror and Copy (RMC) feature will extend the options for disaster recovery and backup solutions.

Integrate

The requirement to integrate z/VSE systems into the larger IT environment is a key part of the z/VSE strategy. By enabling hybrid solutions to leverage z/VSE business data and business logic, customers may be able to achieve substantial advantages. These benefits may include low cost, low risk, and fast time-to-market for new business solutions. Interoperability enhancements in z/VSE V4.3 will include four-digit device addressing providing configuration and infrastructure simplification in mixed environments where customers may run z/VSE together with other IBM System z operating systems, like Linux on System z, z/VM, and/or z/OS. The mapping of four-digit to three-digit device numbers within z/VSE will provide transparency for applications that rely on three-digit device addresses.

Security and systems management enhancements with z/VSE V4.3 will include protection of MQ resources for WebSphere MQ for z/VSE V3 and an SNMP agent for the collection and retrieval of z/VSE-specific system and performance data.

Extend

The z/VSE strategy seeks to enable the effective use of z/VSE together with other platforms, such as Linux on System z, to help customers create modern IT solutions. Linux offers WebSphere, Java™, DB2 Universal Database™, a rich set of development tools, and a growing selection of packaged applications. IBM System z IFLs can provide a robust, highly scalable, cost-effective server environment. z/VM adds exceptional flexibility and manageability through its premier virtualization technology.

z/VM virtualization technology is designed to provide the capability for clients to run a large number of Linux servers in a single mainframe, running with other System z operating systems such as z/OS and z/VSE, or as a large-scale Linux enterprise-server solution. z/VM V6.1 is the newest version of z/VM and is intended to be the base for future z/VM enhancements. z/VM V6.1 provides additional support and exploitation opportunities for many users who have built enterprise-wide automation and infrastructure enhancements on the VM platform in support of their applications, database systems, and on-demand business solutions.

Statement of general direction
Bottom rule

Internet Protocol Version 6 (IPv6)

z/VSE intends to provide an IPv6 solution that will enable z/VSE to participate in an IPv6 network.

IPv6 is the "next generation" protocol designed by the Internet Engineering Task Force (IETF) to replace the current version Internet Protocol, IP Version 4 ("IPv4"). It fixes a number of problems in IPv4, such as the limited number of available IPv4 addresses. IPv6 is expected to gradually replace IPv4, with the two coexisting for a number of years during a transition period.

The availability of IPv6 support may help clients to meet long-term requirements of the commercial community and governmental agencies, like the Department of Defense.
