Specifying how often to dump data to the dump classes

You can control how often volumes are dumped to a dump class by using the FREQUENCY subparameter. This subparameter of the DUMPCLASS parameter works with the DUMPCYCLE parameter to determine when volumes are dumped. For a volume to be dumped, the dump must occur on a Y day in the dump cycle and the number of days specified with the FREQUENCY subparameter must have passed. Use the FREQUENCY subparameter, rather than the DAY subparameter, when you want to use the dump class more than one time in the dump cycle.

In the example system, you want the volumes being dumped in dump class ONEWEEK to be dumped every seven days and the volumes in dump class TWOWEEK to be dumped every 14 days. (You also want the volumes being dumped to dump class FOURWEEK to be dumped every 28 days, but have taken care of this requirement with the DAYS subparameter.) To control dumping to dump classes ONEWEEK and TWOWEEK, you can change the DEFINE DUMPCLASS commands as follows:

DEFINE DUMPCLASS(ONEWEEK AUTOREUSE -
DATASETRESTORE FREQUENCY(7))
DEFINE DUMPCLASS(TWOWEEK NOAUTOREUSE -
NODATASETRESTORE FREQUENCY(14))
