        the hostname, and using the "file" portion as the filename of the database.
        This has the effect of four slashes being present for an absolute file path:

        from using other Oracle tools (like SQLPlus) i.e. user and password are separated
        by ``:`` not by ``/``. Also you can omit ``HOST`` and ``PORT``
        and provide a full DSN string or TNS name in ``NAME`` part.
