Force DBRC usage—DBRC support
When you specify DBRC=FORCE during IMS system generation (IMSGEN), you cannot override DBRC usage with commands and keywords in the PLUSIN control statement data set.
For example, if DBRC=FORCE was specified during IMSGEN and you specify the Index Build function DBRC(NO) keyword, the Index Build function abends with a U0047 abend.
Specifying DBRC=FORCE in the IMSGEN does not guarantee that DBRC will be implemented fully. When you specify DBRC=FORCE, DBRC checks only to see whether the database is registered. DBRC does not ensure that all database data sets are registered; therefore, you could have data sets that are completely unknown to DBRC that are able to obtain valid authorizations. To ensure that all databases and all data sets are under DBRC control, specify FORCER (force registration) when you initialize the RECON data sets. If you run without FORCER, your data sets do not have the level of protection you probably want. Instead, you can register all databases and database data sets and turn the FORCER flag on. You can accomplish these tasks by using the IMS DBRC utility (DSPURX00).
