Performance report

This section contains information about the performance characteristics of releases of CICS® TS. The Performance Report gives a broad understanding of important concepts of CICS performance, and describes many of the performance improvements that can be realized by upgrading CICS. This information was previously published as an IBM® Redbook: IBM CICS Performance Series: CICS TS for z/OS® V5 Performance Report, (SG24-8298).

The information is useful for the following people:
  • System architects who want to understand the performance characteristics and capabilities of a release of CICS TS.
  • Capacity planners and performance analysts who want to understand how an upgrade to the latest release of CICS TS can affect their environment.
  • Application developers who want to design and code highly optimized applications for deployment into a CICS TS environment.
The Performance Report includes the following information:
  • Description of factors that are involved in the interaction between IBM Z® hardware and a z/OS software environment.
  • Definition of key terminology that is used in the descriptions of the results of CICS TS performance benchmarks.
  • Presentation of how to collect the required data, and the methodology used, when you apply Large Scale Performance Reference (LSPR) capacity information to a CICS workload in your environment.
  • Outline of the techniques that are applied by the IBM CICS Performance Team to achieve consistent and accurate performance benchmark results.
  • High-level descriptions of several key workloads that are used to determine the performance characteristics of a CICS TS release.
  • Introduction to the open transaction environment and task control block (TCB) management logic in CICS TS, including a reference that describes how several configuration attributes combine to affect the behavior of the CICS TS dispatcher.
  • Detailed information about the changes in performance characteristics between successive releases of CICS TS.
  • Results of small performance studies from the IBM CICS Performance Team to determine the cost of using a specific CICS TS functional area.
