DBRC controls

IMS Database Recovery Facility uses recovery information that is recorded in the RECON. Therefore, only resources that are registered to DBRC can be used for database recovery by IMS Database Recovery Facility.

For resources that were migrated to different volumes than those registered in the RECON, DBRC determines the correct locations of the resources by doing a search of the system catalog.

DBRC restricts access to database data sets and areas that are undergoing recovery by granting exclusive authorization to IMS Database Recovery Facility.

DBRC performs the following functions for IMS Database Recovery Facility:

• Determines the resources that are required for recovery
• Maintains the status of database data sets and areas that are being processed by IMS Database Recovery Facility
