NULLJOURNALONLY: Specifying that DFSMShsm null the journal

Explanation: NULLJOURNALONLY is an optional parameter of CONTROLDATASETS specifying that DFSMShsm null the journal without making backup copies of the control data sets.

Defaults: None.
Note:
  1. If you specify this parameter, no other parameters for the BACKVOL CDS are allowed.
  2. The journal must have been inhibited by a journal processing error before this parameter is specified, otherwise the BACKVOL CDS NULLJOURNALONLY command will fail.
