Exceptions to the scope of the DEF parameter

There are two parts of a CICS system dump that are not governed by component keywords, and are therefore outside the scope of the DEF parameter.

These are:
  1. The dump summary.
  2. The error message index.
The dump summary is always formatted, even if you specify DEF=0 and no component keywords. The error message index is produced only if an error or information message is output while the CICS dump exit is formatting the dump data, even if you specify DEF=0 and no component keywords. For example:
  • VERBEXIT CICS720 ‘DEF=2,DS=0’ suppresses formatting of the dispatcher (DS) domain; the dump summary is formatted, and all other components are formatted for level 2 only. The error message index is only produced if an error or information message is output while the CICS dump exit is formatting the dump data.

For details of the dump summary and the error message index, see The dump summary and error index.
