You can use IMS
Index Builder to
address many of your day-to-day business problems.
The following scenarios illustrate how you can use IMS
Index Builder to address typical
business problems.
Non-HALDB initial load or reorganization load
After
loading or reloading the prime database, use IMS
Index Builder to process the work
file (DFSURWF1 or HPSRSIDX) to load the secondary indexes. You can
also use IMS
Index Builder with
a dummy DFSURIDX file to initialize indexes that are not to be loaded
yet.
HALDB reload
After reloading
a HALDB, use IMS
Index Builder to
reload the PSINDEX partitions and optionally, the primary indexes
and ILDS.
HALDB online reorganization
After ending online
reorganization for certain partitions, use IMS
Index Builder to reload PSINDEXes
and/or partition primary indexes. Rebuilding ILDS for terminated partitions
would create entries for the last reorganization only.
Individual index reload
During regular production,
an index might be updated extensively, which will decrease performance.
In some cases, an index will become corrupted. Therefore, reallocating
the index is necessary. Use IMS
Index Builder to rebuild the selected
index by scanning the database.
