z/OS Component Trace (CTRACE) Service

IRLM uses the z/OS® component trace (CTRACE) service to trace IRLM activity. Because the trace output is in z/OS CTRACE format, you can use IPCS CTRACE format, merge, and locate routines to process the buffer data.

Use the z/OS TRACE CT command to start, stop, or modify an IRLM diagnostic trace. This command can be entered only from the z/OS master console. Entering the commands requires an appropriate level of z/OS authority. IRLM does not support all the options available on the command. You can also start the IRLM tracing by placing TRACE=YES in the IRLM procedure.
