Your installation should include in its regular schedule a period
of time during which the storage management cycle can run. For example,
you might execute the storage management cycle every day during third
shift. During this time, OAM moves objects between optical disk volumes,
tape volumes, and DASD. If this processing period is short, it might
be necessary to install additional libraries to prevent contention
caused by the following situations:
- Several Object storage groups are processed concurrently (controlled
by the MAXS parameter).
- Multiple drives are used concurrently for a given Object storage
group.
- Optical drive usage is controlled by the DRIVE STARTUP THRESHOLD
storage group parameter in ISMF.
- Tape drive usage is controlled by the use of the TAPEDRIVESTARTUP
(threshold in MB) keyword on the SETOAM statement for each Object
storage group.
