Pluggable database pdb_number cannot access file 'file_name'.
- pdb_number: The PDB identifier that tried to access the file.
- file_name: The name of the file that is being accessed.
Cause
Pluggable databases (PDBs) have restrictions in accessing resources when connected through the DBMS_BACKUP_RESTORE package. The PDB is not permitted to access the file.
Action
Perform the operation through a ROOT connection. (ROOT can access any file.)
