Change accumulation data sets for future use
You must review and set the parameters for managing the change accumulation output data sets.
DBRC records the standard change accumulation in the RECON based on values of the INIT.CAGRP command. The rules for CA and PITCA also apply to REUSE and GRPMAX definitions.
Review the definition for using the CA data sets for future use so that stability is maintained in the recovery environment.
When you specify the REUSE parameter and the maximum number of change accumulation data sets has been reached, the PITCA replaces the change accumulation data set with the oldest change records.
When you specify the NOREUSE parameter, the record of the change accumulation event with the oldest change records is deleted from the RECON.
The physical data set remains intact, but DBRC does not consider the data set for future recovery processing.
