Disk_File[=(Reader_Threads=integer)]

    Specifies that you want to perform a multithreaded restore
    operation from disk files, floppy disks, or other disks external
    to the PC. This qualifier must have been specified on the RMU
    Backup command when the backup files from which you are restoring
    were created.

    The Reader_Threads keyword specifies the number of threads that
    Oracle RMU should use when performing a multithreaded restore
    operation from disk files. You can specify no more than one
    reader thread per device specified on the command line (or in the
    command parameter options file). By default, one reader thread is
    used.

    This qualifier and all qualifiers that control tape operations
    (Label, Loader_Synchronization, Master, Media_Loader, and Rewind)
    are mutually exclusive.
