HALDB offline reorganization

The offline reorganization processes for a HALDB database and other full-function IMS databases are similar: they both consist of an unload and reload of the database.

The HALDB offline reorganization process has advantages over the reorganization process of other full-function databases, such as:

  • You can reorganize one HALDB partition at a time or reorganize multiple partitions in parallel.
  • The self-healing pointer process of HALDB databases eliminates the need to manually update logical relationships and secondary indexes after reorganizing a HALDB database.
  • You do not need to include DD statements for HALDB data sets when you reorganize a HALDB database. HALDB data sets are dynamically allocated.
