Re-creating problems for IBM service

You might be asked to re-create a problem for IBM® service to aid in diagnosis.

Tip: If you are re-creating a problem for IBM service, you should increase the OMVS CTRACE buffer size to 8 MB.

To increase the OMVS CTRACE buffer size to 8 MB, with the parmlib member specifying the required options, specify:

TRACE CT,8M,COMP=SYSOMVS,PARM=CTnBPXxx

As an alternative, you can change the parmlib member to specify the required buffer size. After you capture the dump for the problem, you can reset the trace buffer size to the original setting. The following example shows how to reset the trace buffer size to the original setting:

TRACE CT,xxxK,COMP=SYSOMVS

where xxxK is the size of the required trace buffer.
