If an Archive/Backup job can delay a Restore, use SYSPARM ARCRELTMnn. Specify an Archive/Backup release time of 01 to 99 minutes (default is 00) to use in both Archive and Restore. During Archive, if ARCRELTM is non-zero and there is room on the current volume for the next data set, the time interval since the last output volume swap is compared to ARCRELTM.
If that time interval is greater than or equal to ARCRELTM, a test ENQ for DMSWVOLS is issued for that volume. If a Restore has been waiting for that volume, Archive releases the volume. Restore only issues the DMSWVOLS ENQ if ARCRELTM or MERRELTM is non-zero. Tuning can be done within Archive/Backup with ARCRELTM from 01 to 99 minutes, depending on individual needs.
