Change accumulation run record (CA)

A CA record contains information about a change accumulation data set and can be either available or in use. For each CAGRP record, there can be up to 1024 CA records.

An available CA record is created by an INIT.CA command. This CA record contains the volume serial numbers and the data set name of a data set that is to be used for output from a subsequent run of the Database Change Accumulation utility. You can create available CA records only for those CA groups that are defined with the REUSE parameter.

An in-use change accumulation record is created by a run of the Database Change Accumulation utility. It can be a formerly available CA record that was used during a run of the Database Change Accumulation utility, or it can be a new record with information obtained from the JCL. The information in an in-use change accumulation record includes:

• Data set name
• Volume serial numbers
• Run time of the Change Accumulation utility
• Stop time of the last log volume that the Database Change Accumulation utility processed; or, if the CA processed a subset of logs, the start time of the first log that should be processed on the next execution

You can use a NOTIFY.CA command to create a CA record.
