Use this command to examine the contents of your database root
    (.rdb), storage area (.rda), and snapshot (.snp) files, to
    display current settings for database definition options, and
    to display a list of active database users. The list of database
    users is maintained clusterwide in a VMScluster environment.

    You can display the contents of all pages in any data storage
    area of the database or display the contents of just those pages
    in which rows and indexes for a specific table are stored.

    See the chapter that explains the internal database page format
    in the Oracle Rdb Guide to Database Maintenance for tutorial
    information.

    Depending on your selection of qualifiers, the RMU Dump command
    can list:

    o  A formatted display of any number of pages in the storage area
       of the database.

    o  A formatted display of any number of pages in a uniform
       logical area of the database.

    o  A formatted display of any number of pages in the snapshot
       area of the database.

    o  Header information. (This is listed by default if no
       qualifiers are specified.)

    o  Current users of the database.
