Explanation: ACTIVITY is an optional parameter specifying the recovery of the activity log data set if one exists on the output tape for the specified aggregate group.
Specify the ACTIVITY parameter the first time ARECOVER is executed. Specifying ACTIVITY with the EXECUTE, VERIFY, or PREPARE parameters causes recovery of the activity log, if one exists. If the activity log data set does not exist on the ABACKUP output tapes and ACTIVITY is specified, an error message is issued and ARECOVER processing continues.
Refer to the Aggregate recovery output for the information contained in the activity log data set.
Defaults: None.
