CICS TS V5.2 performance report

This report describes many of the performance-related improvements that are found in CICS® TS for z/OS®, Version 5.2.

The CICS TS 5.2 performance report covers the following topics:

  • Key performance benchmarks that are presented as a comparison against CICS TS 5.2.
  • An outline of improvements that were made regarding the threadsafe characteristics of the CICS run time.
  • Details of the changes that were made to performance-critical CICS initialization parameters and the affect of these updates.
  • Description of all the new and updated monitoring fields, including examples where necessary.
  • High-level views of new functions that were introduced in CICS TS 5.2, 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.

Workload environment

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.

When the results for this report were compiled, the workloads were run on an IBM zEnterprise EC12 model HA1 (machine type 2827). A maximum of 32 dedicated central processors (CPs) were available on the measured logical partition (LPAR), with a maximum of four 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, which were 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 run in a CICS TS for z/OS, Version 5.2 environment. Unless otherwise stated in the results, the CICS TS 5.2 environment was the code available at the general availability (GA) date of 13 June 2014. Several of the performance benchmarks are presented in the context of a comparison against CICS TS for z/OS, Version 5.1. The CICS TS for z/OS, Version 5.1 environment contained all PTFs issued before 18 February 2014. All LPARs used z/OS V2.1.
