z/OS component trace
Use the z/OS® TRACE CT command to start, stop, or modify an internal resource lock manager (IRLM) diagnostic trace.
IRLM does not support all the options that are available on the TRACE command.
You can use the TRACE CT command to trace interactions with a DBMS, member and group events, z/OS locking components, and so on.
The following example shows trace output for a lock request using the DBM and SLM sublevel traces.
The z/OS Interactive Problem Control System (IPCS) subcommand that produced this output is: CTRACE COMP(IRLE) SUB((DBM)) FULL
COMPONENT TRACE FULL FORMAT COMP (IRLE) SUBNAME ((DBM))
