- Create the catalog owner in the third database other than the primary and standby database.
- Create the base catalog.
- Register a database on the base catalog. You must connect to both the catalog and target database in order to register a database.
- Connect to the standby database, the catalog will record the db_unique_name of the standby database automatically.
- List all databases under vpcowner before granting catalog. Of course, we will get errors.
- Grant catalog for database COMPDB to the virtual catalog owner by the base catalog owner.
- List all databases under vpcowner after granting catalog.
- Backup the primary database by vpcowner to test the virtual private catalog.
- Backup the standby database by vpcowner to test the virtual private catalog.
- Check the base catalog by catowner. First, we connect to the primary database.

2 COMPDB 841830157 PRIMARY PRIMDBThe primary database has been registered like the above result, should we register the standby database? The answer is no. If you did, you will get errors because of the same DBID. Actually, you don't have to register the standby database. You can connect to the target database to resync the metadata of the standby database by the following way.
