DBRC and reorganization
DBRC control is essential to the integrity and success of the reorganization process.
DBRC manages the access to the database by granting varying degrees of authorization to the database or by prohibiting access. After a reorganization, all recovery resources relating to the disorganized version of the database are obsolete, and using them will damage the database. DBRC must be notified that a reorganization has taken place and when it took place, so that it will not try to use the obsolete resources for recovery. This section describes how the MAXM Reorg solutions work with DBRC during a reorganization.
The Online Reorg function and Online/Defrag function require full DBRC control, meaning that DBRC must be active, and all databases must be registered. BMC recommends that you register all databases and database data sets and that you turn the FORCER flag on. You can accomplish these tasks by using the IMS DBRC utility (DSPURX00).
HALDBs require that DBRC be active.
