Reallocating HALDB database data sets for offline reorganization

You do not have to delete and redefine HALDB database data sets, other than ILDSs, before you reload them. VSAM data sets must be specified with the REUSE option. HALDB supports this option. This applies to both OSAM and VSAM data sets.

If you delete and redefine partition data sets, but do not reload data into them, you must initialize the partition data sets. If you reload data into the partition data sets after deleting and redefining them, you do not need to initialize the partition data sets.

If you delete and redefine VSAM data sets, you receive a z/OS® IEC161I system message when reloading a partition. This is not an error message. It indicates that a VSAM data set was empty when it was opened. The following example shows the message for an ILDS.
