ORA-02381
        cannot drop string profile
        
        
        Cause
        An attempt was made to drop PUBLIC_DEFAULT or a mandatory profile, which is not allowed due to following restrictions:
- PUBLIC_DEFAULT profile can be dropped only when the database is in migration mode.
- A mandatory profile can be dropped only if it is not set as a mandatory profile in root container (CDB$ROOT) of a multitenant container database (CDB) or in a Pluggable Database (PDB).
        Action
        If you are trying to drop the PUBLIC_DEFAULT profile, try dropping it during migration mode. If you are trying to drop a mandatory profile, check the MANDATORY_USER_PROFILE system parameter setting in the root container (CDB$ROOT) or in a Pluggable Database (PDB) and retry the operation after resetting the MANDATORY_USER_PROFILE system parameter by executing ALTER SYSTEM RESET DDL statement.
