Before and After Comparison

The Before and After Comparison report set is useful when a CICSĀ® applications programmer makes updates to an application as part of a modernization project and needs to compare CPU usage for transactions before and after the changes.

There might be strict guidelines for any CPU increases because of new functionality that is added to the application. The applications programmer wants to know which reports to run to compare the CPU usage for the transactions before and after the changes have been implemented. Based on these reports and analysis, the applications programmer can then consider further changes to the application to ensure the CPU usage is within the provided guidelines.

The report set produces the following reports.

To produce the reports, the following components are used:

Component name Component type Description
CPUSUM form Transaction CPU Analysis
DISPSUM form Transaction Dispatch/CPU Usage
RESPPEAK form Response Time Peak Percentiles
RESPRNGC form Response Time Distribution
RESPRNGM form Response Time Distribution (C+%)
RESPRNGP form Response Time Distribution (%)
RESPWLMP form Response Time Distribution (%)
