JCL for backing up the journal

DFSMSrmm obtains the name of the control data set and journal from the running DFSMSrmm subsystem.

Rule: Do not specify the data set names in the JCL. If you do, the job fails.

You can back up and clear the journal without taking a backup of the control data set. To back up the journal using EDGHSKP, specify the BACKUP parameter as shown in Figure 1.
