Controlling the control data set recovery point

You can restore the DFSMSrmm control data set to any of these recovery points:

The start time of the selected DFSMSrmm control data set backup.
The end time of the selected DFSMSrmm control data set backup. Backups taken with DFSMSdss require the journal backup to have been taken at the same time as the DFSMSrmm control data set backup, otherwise the end time is no different than the start time.
The end time of a journal backup.
The current point in time, which can be achieved as long as you have an appropriate backup of the DFSMSrmm control data set and required backup copies of both the journal and the active journal. Also, the journal backups used must not include any time when the journal was disabled. If you have incomplete journal data because the journal was disabled or a journal backup is damaged or missing, the restored DFSMSrmm control data set might be inconsistent.

You can determine the DFSMSrmm control data set version that has actually been recovered by using information from runs of the EDGBKUP utility during forward recovery and from information in the DFSMSrmm control data set control record.

When you restore a DFSMSrmm control data set with forward recovery, use the details in message EDG6431I to identify the DFSMSrmm control data set time stamp and the time stamp of the journal records used for forward recovery. For example:

EDG6431I THE CONTROL DATA SET TIMESTAMPED 2001/240 06:04:47 WAS FORWARD RECOVERED FROM JOURNAL
         RECORDS BETWEEN 2001/240
EDG6431I CONT:-  06:04:47 AND 2001/241 04:01:12

If you no longer have the EDG6431I message or you did not use forward recovery, you can use the RMM LISTCONTROL subcommand to find the time stamp. In this case, restart DFSMSrmm after your recovery, but before you start tape processing or update records in the DFSMSrmm control data set. Use the RMM LISTCONTROL CNTL subcommand to display the update date and update time values which indicate your recovery point time stamp
