CICS TS for z/OS, Version 6.1 performance report

CICS® TS for z/OS®, Version 6.1 introduces various technical and operational capabilities, including improvements that provide performance benefits over previous CICS releases. This report gives a performance view of the release and provides performance benchmarks that compare this release with CICS TS 5.6.

The performance report for CICS TS 6.1 includes:

• Key performance benchmarks compared with CICS TS 5.6.
• Details of the changes that are made to performance-critical CICS initialization parameters, and the effect of these updates.
• A description of all the updated statistics and monitoring fields.
• High-level views of new function that was introduced in the CICS TS 6.1 release, including performance benchmark results where appropriate.

For a definition of performance terms used in this report, see Performance terminology. A description of the test methodology that is used can be found in Testing with performance workloads. For a full description of the workloads used, see Workload descriptions.

Where reference is made to an LSPR processor equivalent, the indicated machine type and model can be found in the large systems performance reference (LSPR) document. For more information about obtaining and using LSPR data, see Large Systems Performance Reference.

Workload environment

When the results for this report were compiled, the workloads were executed an on IBM z15 model T01 (machine type 8561). A maximum of 32 dedicated central processors (CPs) were available on the measured logical partition (LPAR), with a maximum of six dedicated CPs available to the LPAR used to simulate users. These LPARs are configured as part of a parallel sysplex. An internal coupling facility was co-located on the same central processor complex (CPC) as the measurement and driving LPARs, connected by using internal coupling peer (ICP) links. An IBM System Storage DS8870 (machine type 2424) was used to provide external storage.

This report presents the results of several performance benchmarks when executed in a CICS TS 6.1 environment. Unless otherwise stated in the results, the CICS TS 6.1 environment was the code available at general availability of the product. Several of the performance benchmarks are presented in the context of a comparison against CICS TS 5.6. The CICS TS 5.6 environment using the code available at general availability of the product. All LPARs used z/OS Version 2.4.
