If no trace options are supplied in a named parmlib member or in a REPLY to a TRACE operator command, RRS component trace will trace only unexpected events. You can find information about the CTncccxx (component trace) parmlib member in z/OS MVS Initialization and Tuning Reference, and information about component trace for RRS in z/OS MVS Diagnosis: Tools and Service Aids.

RRS performance can be severely impacted by component tracing. For this reason, a CTRACE parmlib member for RRS is not provided since you might start CTRACing causing performance degradation without needing or knowing about it. However, for problem determination, CTRACing can provide valuable information. Member ATRCTRRS supplied in SYS1.SAMPLIB is available with an optimal set of CTRACE parameters used for debugging RRS problems. The BUFSIZE in the sample has been established to hold 10-30 minutes of tracing on most systems. When problem determination is needed, see the SET-UP and ACTIVATION instructions in the ATRCTRRS sample.
