Disabling and enabling HALDB partitions

You can temporarily remove partitions from an active HALDB database by disabling the partition.

Disabled partitions appear to be deleted from the HALDB database and are unavailable for use by IMS and most utilities; however all of the records related to the partition, such as the partition ID number and image copy records, are retained by DBRC in the RECON data set.

You would normally disable a partition that you plan to delete. Disabling the partition allows you to test the proposed deletion without actually deleting the partition and the recovery information associated with it. After you disable a partition, you can delete it or restore the partition to the HALDB database by enabling and recovering the partition.
