This IBM® Redpaper™ publication highlights the findings of a study about the factors that affect the performance of IBM CICS® transactions that access IBM DB2® resources through the CICS DB2 attachment facility. Most of the study used the following hardware and software:
- A 2097-E64 logical partition (LPAR) with three dedicated central processors
- IBM z/OS® 1.11
- IBM CICS Transaction Server V4.1
- IBM DB2 V9
This paper can assist application designers and developers in developing CICS applications that perform optimally within the CICS environment. It can also provide guidance to CICS systems programmers and administrators about how to configure regions to optimize access to DB2 subsystems.
This paper is one of a series focused on CICS performance written by members of the IBM Hursley CICS development community. The subject matter in this series is based on feedback from CICS customers.
