Journalmodel considerations in a CICS TS z/OS CMAS

The CMAS grouplists for CICS® Transaction Server for z/OS® include the CICS-supplied group, DFHLGMOD. If the log stream names used by the DFHLGMOD group are not appropriate for your environment, copy group DFHLGMOD to a new group, where you can make your amendments. Finally, add the new group to the CMAS grouplist.

See Defining the logger environment for CICS journaling for details on how to define log streams.

Note:
Do not operate the CMAS with log streams that are defined as DUMMY. This may cause problems when recovering the CSD or CICSPlex® SM data repository (EYUDREP).

See CMAS journaling for details about the various CMAS journaling options that you can activate.
