The point-in-time (PIT) restore job of the root fails with an error message.
RMAN-05105: Specifying CDB$ROOT database is not supported
RMAN does not support this type of operation on the root for following reasons:
- The root holds the metadata for all other pluggable databases (PDB) in that container database (CDB). The CDB might also go in an inconsistent state because of the metadata inconsistencies between the PDBs and the root.
- The root also holds the undo tablespace, which is common (shared) among all the PDBs. If a user restores the root to a PIT, the undo tablespace that holds the undo data of other containers will be lost.
Recover the whole container database instead of recovering only the root.
