Software requirements for running z/OS V2R3
Careful planning is needed to ensure that you run the appropriate software with z/OS® V2R3 on your target system. This topic lists software requirements to consider.
- This topic does not describe program requirements that are related to systems in a sysplex using the coupling facility. For that information, see Parallel Sysplex.
- Requirements that are listed in this topic reflect the minimum levels.
- Some IBM products and z/OS elements and features have comparable non-IBM equivalents. This topic reflects only IBM software.
- z/OS does not support service for client operating systems whose service is withdrawn by the operating system manufacturer.
- z/OS V2R3 has an overall dependency on IBM 64-bit SDK for z/OS, Java™ Technology Edition, V8 (5655-DGH) and IBM 31-bit SDK for z/OS, Java Technology Edition, V8 (5655-DGG). Generally, this dependency exists for new or enhanced functions in z/OS. Older functions that are unchanged from previous releases, and have lower Java requirements, are expected to work with earlier supported releases of Java. For the specific Java dependencies for each element, see Table 2.
Determine which PTFs are needed for z/OS V2R3
You must determine which PTFs are required for minimum support on z/OS V2R3, and which PTFs are required to use specific functions in z/OS V2R3.
- Identify the PTFs for both minimum support and functional support with a FIXCAT called
IBM.TargetSystem-RequiredService.z/OS.V2R3
, in enhanced HOLDDATA. The HOLDDATA type FIXCAT (fix category) is used to associate an APAR to a particular category of fix for target system PTFs identified as levels. - To identify the PTFs on your current system that would be needed for your upgrade to z/OS V2R3, run the SMP/E command REPORT MISSINGFIX. You might, for example, use a command such as the following to identify PTFs for the CICS® CSI:
SET BDY(GLOBAL). REPORT MISSINGFIX ZONES(CICS51T) FIXCAT(IBM.TargetSystem-RequiredService.z/OS.V2R3).
- To determine what PTFs are needed and not yet installed, run the command REPORT MISSINGFIX against the global zones that you use to support your middleware and application products.
Determine the minimum product or functional release levels for z/OS V2R3
IBM middleware and application products require a specific release to run on z/OS V2R3. You cannot use the FIXCAT support to determine these release levels. Instead, you can refer to the tables in this section.
Table 1 lists the IBM middleware and application products that require a specific version of the product to run on z/OS V2R3.
If you use this IBM product... | You need this product level (in most cases achieved with PTFs) |
---|---|
IBM Application Performance Analyzer for z/OS | IBM Application Performance Analyzer for z/OS requires the 14.1 level at a minimum. Earlier levels of this product are not supported for use with z/OS V2R3. |
IBM Security zSecure products:
|
IBM Security zSecure products require the 2.3.0 level at a minimum. Earlier levels of this product are not supported for use with z/OS V2R3. |
Table 2 lists the functions of z/OS V2R3 that require specific optional features, IBM middleware products, or IBM application products.

DFSORT | DFSORT Performance Booster for The SAS System requires enabling support from SAS Institute Inc. |
Distributed File Service |
The IP Services component of the z/OS Communications Server base element must be operational. SMB print serving support requires the z/OS Infoprint Server feature to be operational. SMB password encryption requires the OCSF component of the z/OS Cryptographic Services base element to be operational to use hardware encryption capabilities.

HCD | To migrate from the active switch configuration or to activate a switch configuration,
Tivoli System Automation for z/OS (5698-SA3) is required. To perform the verification/priming function of the active I/O configuration, Tivoli System Automation for z/OS (5698-SA3) is required. Use of the CHPID Mapping Tool is recommended for mapping logical CHPIDs to physical channels (PCHIDs) and creating input to HCD/IOCP. The tool is a workstation-based Java application available from the Resource Link home page. It updates the IOCP input file with the PCHID values and can generate reports to help with cabling. Note:
Beginning with z/OS V2R1 (HCD version 2), you can verify the
active or target configuration by using z/OS discovery and
I/O Autoconfiguration (zDAC), if Tivoli System Automation
(TSA) I/O operations is not installed or not running. This action is possible for a server after the
z196 and z114 generations supporting zDAC and for a system in the local sysplex, which is capable
for dynamic activates. The verification is limited to FICON
attached storage devices.

Note: Other browsers might work with Infoprint Central V2R3, but have not been tested. Using
untested browsers might result in some Infoprint Central functions that are unavailable.
Infoprint Server can use the following transform products to convert data streams from one format
to another:
The following transform products are no longer supported as of z/OS V2R1:
Version 1 Release 2 of the following transform products are now
available and can also be used to convert data streams from one format to another on z/OS
V2R1 and later releases:
The transforms can convert (1) PCL, PostScript, PDF, SAP R/3, and Xerox print data to AFP format for printing by PSF for z/OS V4 (5655-M32) on AFP printers, and (2) AFP, line data, and XML data streams to PCL, PostScript, or PDF format for printing, e-mailing, or presenting on the web. The Infoprint Coaxial Printer Support for z/OS (5655-N62) for printing to SNA-controlled printers is no longer supported as of z/OS V2R3. The workstation operating system that is required to use the Infoprint Port Monitor is Windows 7, Windows 8.1, Windows 10, Windows Server 2012, or Windows Server 2016. |

Library Server | The IBM HTTP Server base element must be
operational. Use of extended shelf support requires XML Toolkit for z/OS V1R10 (5655-J51). Indexing or reindexing of any type of shelf requires XML Toolkit for z/OS V1R10 (5655-J51). Use of InfoCenter support requires XML Toolkit for z/OS V1R10 (5655-J51), plus IBM 31-bit SDK for z/OS, Java Technology Edition, V7.1 (5655-W43) or V8 (5655-DGG).
