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

       /NODE=workstation_display

    Defines the workstation on which you want to display DECwindows
    applications. The node name you provide cannot be a cluster alias
    (a name that represents multiple nodes configured in an OpenVMS
    Cluster), but must instead identify an actual node.

    You must create a workstation display device with the
    /CREATE qualifier before you can redirect the output from
    applications to other workstations. Do not enter the SET
    DISPLAY/NODE=workstation_display command without having
    previously specified the /CREATE qualifier.

    When you specify the /CREATE qualifier without the /NODE
    qualifier, the workstation defaults to the current node.

    Make sure that you are authorized to display applications
    on the workstation you specify. For more information about
    using the DECwindows Session Manager to authorize yourself to
    display applications from other nodes, refer to the DECwindows
    documentation.

    Each node, both source and destination, must be defined in
    the other's network node database. For example, to display
    applications on node HUBBUB from ZEPHYR, HUBBUB must be entered
    in ZEPHYR's network node database, and ZEPHYR must be entered
    in HUBBUB's network node database. In addition, users on ZEPHYR
    must be authorized in the DECwindows Session Manager to display
    applications on HUBBUB. For information about entering nodes in a
    network node database, refer to the DECnet for OpenVMS Networking
    Manual and the DECnet for OpenVMS Network Management Utilities
    manual. These manuals are available on the Documentation CD-ROM.
