The RdbALTER utility provides a low-level patch capability that
    allows you to repair corruption on Oracle Rdb database pages.
    In addition, it allow you to relocate database root, area, and
    snapshot files to other disks or directories. This is helpful
    when you move a database from a single node to a VAXcluster or
    VMScluster environment.

    You must have the RMU$ALTER privilege or the OpenVMS SYSPRV or
    BYPASS privilege to use RdbALTER.

    RdbALTER can receive command lines through command files or
    directly from the user's terminal.

    You can abbreviate any ofthe RdbALTER command keywords. The only
    restriction is that you must specify enough characters to avoid
    ambiguity.

    RdbALTER interprets the exclamation point (!)  as a comment
    character. Any characters on a line following an exclamation
    point are disregarded by RdbALTER.
