Could not register this external database because it has already been registered in OCI
If this error is displayed when registering an External Database, here are the likely causes and what you can do to resolve the issue:
- Cause: The External Database (CDB, PDB, or non-CDB) is already registered
in the same compartment.
Solution: Check whether the External Database is already registered in the same compartment and enable Database Management for the already registered database resource, instead of registering it again.
- Cause: If attempting to register an External PDB using the
associated CDB's service name details, then this error may be displayed as the
CDB is already registered in the same compartment.
Solution: Provide the correct External PDB details. You can verify the service name information from the database using the following query:
select value from v$parameter where name like '%service_name%'
