Change accumulations


The Recovery utility uses a change accumulation data set if it is available, but you are never required to run change accumulation before the recovery.

The change accumulation data set contains the latest change record for each record in the database. Because previous change records for a individual database record are discarded during change accumulation and are therefore not processed during recovery, using a change accumulation data set can reduce elapsed time for a recovery. For more information, see Identifying-input-change-accumulations.
