Automatic archiving

If you have a large system with a lot of activity, you can minimize your intervention in the archiving process by using automatic archiving. It will eliminate the need to continually monitor logging to determine when to archive.

By default, IMS archives each OLDS when it is full. However, you can control how often archiving occurs by specifying how many OLDSs must be full before IMS archives them. Use the ARC= execution parameter or the AUTOARCH keyword of the /START command to control automatic archiving.

Recommendation: You must archive an OLDS before IMS can reuse it; be sure to archive frequently enough to avoid running out of OLDS space. If you run out of OLDS space, IMS waits until OLDS space becomes available.
