You can use the CICS® PA plug-in for CICS response time, user CPU time, threadsafe, storage usage, and file request activity analysis. You can view the data selected for analysis as pie charts, bar charts, or timeline charts. You can also view the properties and values of a transaction ID.
Before you begin, check that the analysis that you want is available. By default, all charts are available, but you can set CICS PA plug-in preferences to disable specific categories of analysis and restrict the associated charts. If the analysis you require is not available, check the Categorization enablement preferences. See CICS Performance Analyzer Preferences.
