ORA-65040: operation not allowed from within a pluggable database

 Starting 12c, after introduction of pluggable databases, there are certain operations that can be performed only at the root container level. If you try to execute that operation/SQL within the PDB, you will receive ORA-65040. In this case you must ensure that the command you are executing is being executed at the root container level. Following is only one example of such operations that can only be performed from the root container.
