storage-area-name[,...]

    A storage area name from the database. This parameter is
    optional. Use it in the following situations:

    o  When you want to change the values for thresholds or blocks
       per page.

    o  When you want to change the names specified with the Snapshot
       or the File qualifier for the restored database.

    o  If you want to restore only selected storage areas from your
       backup file, you must use the Area qualifier and specify the
       names of the storage areas you want to restore in either the
       storage-area-name parameter in the RMU Restore command line,
       or in the file specified with the Options qualifier.

       To use this option, specify the storage area name rather than
       the file specification for the storage area.

    By using the RMU Backup and RMU Restore commands, you can back up
    and restore selected storage areas of your database. This Oracle
    RMU backup and restore by-area feature is designed to:

    o  Speed recovery when corruption occurs in some (not all) of the
       storage areas of your database.

    o  Reduce the time needed to perform backup operations because
       some data (data in read-only storage areas, for example) does
       not need to be backed up with every backup operation performed
       on the database.

    If you plan to use the RMU Backup and RMU Restore commands to
    back up and restore only selected storage areas for a database,
    you must perform full and complete backup operations on the
    database at regular intervals. A full and complete backup is a
    full backup (not an incremental backup) operation on all the
    storage areas in the database. If the database root (.rdb) file
    is corrupted, you can only recover storage areas up to (but not
    past) the date of the last full and complete backup operation.
    Therefore, Oracle Corporation recommends that you perform full
    and complete backup operations regularly.

    If you plan to back up and restore only selected storage areas
    for a database, Oracle Corporation strongly recommends that you
    enable after-image journaling for the database (in addition to
    performing the full and complete backup operation on the database
    as described earlier). That is, if you are not backing up and
    restoring all the storage areas in your database, you should have
    after-image journaling enabled. This ensures that you can recover
    all the storage areas in your database in the event of a system
    failure. If you do not have after-image journaling enabled and
    one or more of the areas restored by RMU Restore are not current
    with the storage areas not restored, Oracle Rdb will not allow
    any transactions to use the storage areas that are not current
    in the restored database. In this situation, you can return to a
    working database by restoring the database, using the backup file
    from the last full and complete backup operation on the database
    storage areas. However, any changes made to the database since
    the last full and complete backup operation was performed are not
    recoverable.

    If you have after-image journaling enabled, use the RMU Recover
    command to apply transactions from the .aij file to storage areas
    that are not current after the RMU Restore command completes.
    When the RMU Recover command completes, your database will be
    consistent and usable.
