One or more spaces separate command parameters and their
    qualifiers from the command keyword. Command parameters define
    the file, index, or entity on which the command will act. In most
    cases, you can omit the parameter from the command line and enter
    it in response to a prompt.

    In the following sample command, RMU/DUMP is the command keyword
    and MF_PERSONNEL is the command parameter:

    $ RMU/DUMP MF_PERSONNEL

    When a storage area is a command parameter in an Oracle RMU
    command, use the storage area name instead of the storage area
    file specification. For example:

    $ RMU/RESTORE/AREA MF_PERSONNEL.RBF EMPIDS_LOW/THRESHOLDS=(65,75,80)

    Some commands, such as the RMU Backup command, require two or
    more command parameters. If you provide all parameters (for
    example, a root file specification and a backup file name),
    there are no prompts. Other commands, such as the RMU Restore
    command, have one required and one optional command parameter.
    In this case, there are no prompts if you provide the backup
    parameter but not the storage area parameter. However, if you do
    not provide either parameter, Oracle RMU prompts for both.
