Concurrent recovery facilitates the recovery of multiple media sets using concurrent recovery sessions. Multiple media sets are typically created when you perform backups using parallel device resources. The saved objects on one media set can be restored concurrently on one session, while the objects on another media set are recovered using another session, provided you have sufficient device resources.
The following step is added to the recovery report if there is more than one media set used in the recovery. Information in the step includes:
**************************************************************************************************** __ STEP 012 : Recover Media Sets Concurrently Start date/time __________________ Stop date/time __________________ Duration _________________ The recovery includes objects saved on multiple media sets having the following beginning volume identifiers: HPK601 HPK620 LN4071 LN4074 LN4384 MJVT01 MJV21 872ACV 873ACV You can recover these objects using concurrent sessions using the submit to batch function on the recovery. You are not required to run concurrent sessions, however this could save you time on recovery. If you do not want to use the concurrent restores, then skip to the next recovery step in the report. To set up concurrent sessions the following needs to be done: a) Put all scheduled jobs on hold. You can achieve this by doing the following: -STRSBS QSYSWRK -WRKJOBSCDE and select option 3 for each scheduled job to put all scheduled jobs on hold. NOTE: If you are using a different job scheduler, then the process to hold jobs will be different and the WRKJOBSCDE command will not show the jobs to hold. b) Setup the job queue to handle multiple batch jobs. - Run a CHGJOBQE on the job queue that will be receiving the batch jobs and set MAXACT and all MAXPTY* parameters to the number of concurrent restores that are to be ran. These will have to be reset to the original values when the restores are complete. c) Run the following subsystem steps: - Start the subsystem that handles batch processing. - End subsystem Q1ABRMNET if it starts. d) Type the following recovery command steps: - STRRCYBRM OPTION(*SYSTEM) ACTION(*RESTORE) and press "Enter". 1. Enter *VOLSET for "Select action" parameter and enter the volume id from the list of beginning volumes into the "Select volume" parameter. 2. Press F16, this will select all the recovery items with that volume set. 3. Press F14 to submit the recovery to batch. Repeat the following steps for each volume set you wish to recover from: - STRRCYBRM OPTION(*RESUME) 1. Enter *VOLSET for "Select action" parameter and enter the volume id from the list of beginning volumes into the "Select volume" parameter. 2. Press F16, this will select all the recovery items with that volume set. 3. Press F14 to submit the recovery to batch.
----- Attention --------------------------------------------------- Press F9 on the Select Recovery Items display to go to the Restore Command Defaults display. __ Ensure the tape device name or media library device name is correct for the Device prompt. __ Ensure *SAVLIB is specified for the Restore to library prompt. __ Ensure *SAVASP is specified for the Auxiliary storage pool prompt. If you are recovering to a different system or a different logical partition, you must specify the following: __ *ALL for the Data base member option prompt. __ *COMPATIBLE for the Allow object differences prompt. __ *NONE for the System resource management prompt. __ Select *NEW for Restore spooled file data to recover saved spooled files concurrently with restored output queues. Press "Enter" to return to the Select Recovery Items display. --------------------------------------------------------------------- e) Use the WRKSBMJOB to monitor the restores that have been submitted to batch and check for errors/successes. NOTE: Ensure there are sufficient recovery devices to handle the amount of concurrent restore jobs. ***************************************************************************************************
