Use Stand-Alone Prefix Update to run the Prefix Update function as a stand-alone utility. Stand-Alone Prefix Update reads DFSURWF3 records from the Prefix Resolution function or the IMS™ Database Prefix Resolution utility, and updates the prefix of each segment whose prefix information was affected by a database load or reorganization.
If DBRC is active, Stand-Alone Prefix Update issues a NOTIFY.REORG command for each database that has been updated.
The following figure shows the general data flow for Stand-Alone Prefix Update.
