Change accumulation groups

You can use DBRC to group DBDSs for which the Database Change Accumulation utility accumulates changes. These groups of DBDSs are called change accumulation groups.

You can define a change accumulation group by using the DBRC INIT.CAGRP command to write a CAGRP record in the RECON data set. Within this record, DBRC lists the DBDSs that make up the change accumulation group, identified by their database names and data set DD names, and the recovery period, identified by the RECOVPD keyword. A change accumulation group can have a maximum of 32,767 members.

Before you can use the INIT.CAGRP command to define the change accumulation group, you must identify each member to DBRC using an INIT.DBDS command. A DBDS can belong to only one change accumulation group.

You can add or delete members of a change accumulation group using the CHANGE.CAGRP command.
