Amending log stream names in a CMAS

If the log stream names used by the CICS-supplied DFHLGMOD group are not appropriate for your environment, copy group DFHLGMOD to a new group, where you can make your amendments. Add the new group to a CSD list and ensure that the list is included for your CMAS, using the SIT GRPLIST system initialization parameter.

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

Do not operate the CMAS with log streams that are defined as DUMMY. Dummy log streams can 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.
