Recovering the IMS catalog when IMS manages ACBs

When the IMS management of ACBs is enabled, the IMS directory data sets must be recovered in addition to the other HALDB database data sets that are associated with the IMS catalog.

Depending on your system configuration, you can recover the IMS catalog data sets with either of the two methods:

Recovering from the backup ACBLIB by using the IMS Catalog Populate (DFS3PU00) utility.
Recovering from database image copies and the log data sets when the backup ACBLIB cannot be created.
