DBRC (Database Recover Control) is a feature included in the IMS Database system to permit easier recovery of IMS databases. DBRC maintains information required for database recoveries, generates recovery control statements, verifies recovery input, maintains a separate change log for database data sets, and supports sharing of IMS databases by multiple IMS subsystems.
