Parameters for Resolving Problems

We provide a set of special parameters, as listed, for use in diagnosing CA OPS/MVS operating problems.

Important! Set these parameters only when a CA Customer Support representative asks you to do so.

DEBUG xxxx parameters
These parameters set debugging flags for various CA OPS/MVS routines. The xxxx is a set of characters specifying which routine to trace. For example, the DEBUGSSRW parameter allows tracing for the CA OPS/MVS SSRW routine or DEBUGEXTSEC parameter allows tracing for CA OPS/MVS external security checks.
EPIDEBUG parameter
This parameter allows the CA OPS/MVS EPI facility to trace VTAM exits.
IMSRELxCHANGEID, IMSRELxCHANGELEN, IMSRELxCHANGEOFF, IMSRELxLEN, IMSRELxOFF, IMSRELxOFFSET, IMSRELxSTRING, and IMSRELxSVC parameters
These parameters provide information about CA OPS/MVS processing for IMS SVCs.
OCDEBUG parameter
This parameter activates CA OPS/MVS messages that can help to determine throughput from executing commands.
TRACExxxx parameters
These parameters activate tracing for various CA OPS/MVS entries and exits. The xxxx value represents the name of the item to be traced. For example, the TRACE3X parameter controls tracing of the UX31 exit.

For more information about these parameters, ask your CA Customer Support representative.
