Confirm
    Noconfirm

    Specifies that RMU Restore notify you of the name of the database
    on which you are performing the incremental restore operation.
    You can thus be sure that you have specified the correct .rdb
    file name to which the incremental backup file will be applied.
    This is the default for interactive processing.

    Confirmation is especially important on an incremental restore
    operation if you have changed the .rdb file name or created a new
    version of the database during a restore operation from the full
    backup file. (You must specify the Root qualifier also to create
    new version or change the .rdb file name.)

    Specify the Noconfirm qualifier to have RMU Restore apply the
    incremental backup file to the database without prompting for
    confirmation. This is the default for batch processing.

    RMU Restore ignores the Confirm and Noconfirm qualifiers unless
    you use the Incremental qualifier.
