The aim of this paper is to show tools and techniques that can be used to understand the performance characteristics of an IBM® CICS® performance benchmark. It describes why it is important to understand whether other work on your systems can interfere with the system under test. It looks at an example CICS Transaction Server (CICS TS) configuration and describes how monitoring tools, including Resource Measurement Facility™ (IBM RMF™) and Workload Manager (WLM) can be used to collect and report performance data.
