Media_Loader
    Nomedia_Loader

    Use the Media_Loader qualifier to specify that the tape device
    receiving the backup file has a loader or stacker. Use the
    Nomedia_Loader qualifier to specify that the tape device does
    not have a loader or stacker.

    By default, if a tape device has a loader or stacker, Oracle
    RMU should recognize this fact. However, occasionally Oracle RMU
    does not recognize that a tape device has a loader or stacker.
    Therefore, when the first backup tape fills, Oracle RMU issues a
    request to the operator for the next tape, instead of requesting
    the next tape from the loader or stacker. Similarly, sometimes
    Oracle RMU behaves as though a tape device has a loader or
    stacker when actually it does not.

    If you find that Oracle RMU is not recognizing that your tape
    device has a loader or stacker, specify the Media_Loader
    qualifier. If you find that Oracle RMU expects a loader or
    stacker when it should not, specify the Nomedia_Loader qualifier.

    Synonymous with the Owner qualifier. See the description of the
    Owner qualifier.
