B、 Open the CDB instance in restricted mode. In CDB$ROOT, execute ALTER DATABASE LOCAL UNDO ON, and create an UNDO tablespace in each PDB, then restart the CDB instance.
C、 Open the CDB instance in restricted mode. In CDB$ROOT, drop the UNDO tablespace. Execute ALTER DATABASE LOCAL UNDO ON in each PDB, and then restart the CDB
Instance.
D、 Open the CDB instance in read-only mode. In CDB$ROOT, execute ALTER DATABASE LOCAL UNDO ON, and then change the CDB to read/write mode.
E、 Open the CDB instance in upgrade mode. In each PDB, execute ALTER DATABASE LOCAL UNDO ON, create an UNDO tablespace, and then restart the CDB instance.
