    Invokes the RdbALTER utility for Oracle Rdb.

                                   NOTE

       Oracle Corporation recommends that the RdbALTER utility be
       used only as a last resort to provide a temporary patch to a
       corrupt database. The RdbALTER utility should not be used as
       a routine database management tool.

       Use the RdbALTER utility only after you fully understand the
       internal data structure, know the information the database
       should contain, and know the full effects of the command.
       Because of the power of the RdbALTER utility and the
       cascading effects it can have, Oracle Corporation recommends
       that you experiment on a copy of the damaged database before
       applying the RdbALTER utility to a production database.

    To invoke the RdbALTER utility, enter the RMU Alter command in
    the following format:

    $ RMU/ALTER [root-file-spec]

    The optional root file parameter identifies the database you want
    to alter. If you specify this parameter, you automatically attach
    to the specified database. If you do not specify this parameter,
    you must use the RdbALTER ATTACH command. See the RdbALTER Help
    for more information on the ATTACH command.

    The RMU Alter command responds with the following prompt:

    RdbALTER>

    This prompt indicates that the system expects RdbALTER command
    input.

    To access the RdbALTER Help file, enter the following:

    RdbALTER> HELP

    To use the RMU Alter command for a database, you must have the
    RMU$ALTER privilege in the root file ACL for the database or the
    OpenVMS SYSPRV or BYPASS privilege. You must have the OpenVMS
    SYSPRV or BYPASS privilege if you are using an RMU Alter command
    to change a file name.
