DUMPCYCLE: Specifying the automatic dump cycle

Explanation: DUMPCYCLE is an optional parameter specifying the days in a cycle when the automatic dump process should run.

DUMPCYCLE(cycle): For cycle, substitute a string of alphabetic Ys and Ns. Each Y represents a day in the cycle when automatic dump is to run, and each N represents a day in the cycle when automatic dump is not to run. You can represent up to 31 days with the Ys and Ns. When you specify cycle, the current day is the first day of the cycle unless you specify the cycle start date.

CYCLESTARTDATE can be used with this parameter and is covered separately under CYCLESTARTDATE: Specifying the start date of a cycle.

Defaults: None.
Note:
  1. Cycle must be defined sometime before the automatic dump process is permitted to run.
  2. Cycle is ignored if a volume dump is requested with the BACKVOL command.
  3. Cycle has no meaning unless the AUTODUMPSTART and BACKUP parameters of the SETSYS command are specified for the DFSMShsm startup.
  4. Dump cleanup also runs on an ‘N’ day in the dump cycle. Cleanup functions include expiration of expired dump copies and deletion of excess dump VTOC copy data sets.
