VMS Help CONFIGURE, Qualifiers  *Conan The Librarian (sorry for the slow response - running on an old VAX)

1 - /ENGAGE

    Causes the GCU to engage (load, validate, and activate) the
    specified OpenVMS Galaxy Configuration Model without displaying
    the graphical user interface. After validation, the specified
    model becomes the active system configuration.

    This qualifier allows system managers to restore the OpenVMS
    Galaxy system to a known configuration, regardless of what
    dynamic resource reassignments may have occurred since the
    system was booted. This command can be embedded in DCL command
    procedures to automate configuration operations.

2 - /VIEW

    When used in conjunction with /ENGAGE and a model parameter,
    causes the GCU to load, validate, activate, and display the
    specified configuration model.
