Change accumulation group record (CAGRP)

A CAGRP record identifies a change accumulation (CA) group. This record includes up to 32,767 names of DBDSs whose change records are accumulated during one run of the Database Change Accumulation utility. Each DBDS (for which DBRC is controlling recovery) can be a member of only one CA group in order for the Database Change Accumulation utility to accumulate its changes. You specify the CAGRP name in the INIT.CAGRP command that you use to create a CAGRP record in the RECON data set.

The CAGRP record contains the name of a member of a partitioned data set. This member contains the skeletal JCL that is used to generate the JCL to run the Database Change Accumulation utility for this CA group. The CAGRP record also contains an indicator that specifies whether change accumulation data sets that correspond to this group can be reused. It contains an indication of the maximum number of change accumulation data sets that are maintained for the group and the recovery period.
