Enabling trace facilities

OMEGAMON for CICS on z/OS has dynamic enablement for Application Trace for active tasks; this occurs as a result of Resource Limiting being implemented with a specific CICS Global user exit.

The Application Trace feature is enabled automatically through the following parameter in the <STARTUP_CONTROL> section of the OMEGAMON Global Data Area:
ENABLE_APPLICATION_TRACE=AUTO

When you specify the AUTO parameter, resource limiting or a user activates the trace for a specific transaction; it does not mean that a trace is collected for all transactions.

If you want application trace activated for the life of a CICS region, use the Application Trace Facility Status panel in the Control menu of the OMEGAMON for CICS (3270) interface. In OMEGAMON for CICS on z/OS, the Sample Trace Transaction command can be used to automatically enable trace for the life of the CICS region until you decide to explicitly disable it at a later date.
