Explanation:
Manually Resynchronizing the Recovery Catalog
Use RESYNC CATALOG to force a full resynchronization of the recovery catalog with a
target database control file. You can specify a database unique name with RESYNC FROM
DB_UNIQUE_NAME or ALL, depending on whether you want to resynchronize a specific
database or all databases in the Data Guard environment.
Typically, you would perform this operation after you have run the CONFIGURE command
for a standby database, but have not yet connected to this standby database.
1. Start RMAN and connect to a target database and recovery catalog.
2. Mount or open the target database:
RMAN> STARTUP MOUNT;
3. Resynchronize the recovery catalog.
RMAN> RESYNC CATALOG;
