Unexpected Increase in CPU

The Unexpected Increase in CPU report set is useful when a CICSĀ® systems programmer sees a notification that some of the transactions on one or more CICS systems are experiencing increases in CPU time.

The increase in CPU time information was provided by the delivery manager from service level agreement (SLA) reports. The systems programmer wants to know which reports to run to determine the causes of the increase in CPU. Based on these reports and analysis, the systems programmer can then consider tuning options as well as further analysis and monitoring.

The report set produces the following reports:

To produce the reports, the following components are used:

Component name Component type Description
BADCPU form Top 20 Worst CPU Times
CPU5SUM form Transaction CPU Analysis (V5)
CPUSUM form Transaction CPU Analysis
DISPOVRV form Dispatcher Statistics Overview
DISPSUM form Transaction Dispatch/CPU Usage
MONTORNG form Monitoring Statistics Summary
