The RMU Verify command checks the internal integrity of database
    data structures. Oracle Corporation strongly recommends that
    you verify your database following any kind of serious system
    malfunction. You should also verify your database as part of
    routine maintenance, perhaps before performing backup operations.
    You can use the various qualifiers to perform verification of the
    maximum number of database areas in the time available.

                                   NOTE

       If you use the RMU Convert command with the Nocommit
       qualifier to convert a database created prior to Oracle Rdb
       Version 6.1, and then use the RMU Convert command with the
       Rollback qualifier to revert to the prior database structure
       level, subsequent verify operations might return an RMU-W-
       PAGTADINV warning message. See the Usage_Notes help entry
       under this command for details.
