ORA-00023
        session references process private memory; cannot detach session
        
        
        Cause
        An attempt was made to detach the current session when it contains references to process private memory.
        Action
        A session may contain references to process memory (PGA) if it has an open network connection, a very large context area, or operating system privileges.  To allow the detach, it may be necessary to close the session's database links and/or cursors.  Detaching a session with operating system privileges is always disallowed.
