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

    The SCA Control Program (SCACP) utility is designed to monitor
    and manage cluster communications. (SCA is the abbreviation for
    Systems Communications Architecture, which defines the mechanisms
    that enable nodes in an OpenVMS Cluster system to communicate.)

    With SCACP, you can modify cluster communications operational
    parameters to specify management characteristics of cluster
    communications paths. You can look at status and counters that
    describe the operational state of these cluster communications
    paths.

    In OpenVMS Version 7.3, you can use SCACP to manage SCA use of
    LAN paths.  In the future, SCACP might be used to monitor and
    manage SCA communications over other OpenVMS Cluster interconnects.

                                   NOTE

       SCACP requires you to have the DIAGNOSE and SYSPRV privileges
       to issue SCACP commands.

    Format

      RUN SYS$SYSTEM:SCACP

    To invoke SCACP, enter the following command at the DCL prompt:

    $ RUN SYS$SYSTEM:SCACP

    SCACP displays the following prompt, at which you can enter SCACP
    commands using the standard rules of DCL syntax:

    SCACP>

    As an alternative, you can enter the RSX command MCR, which
    expands to RUN SYS$SYSTEM:

    $ MCR SCACP

    With the MCR command, you can invoke SCACP and supply a command
    in one command string. With any SCACP command invoked in this
    way, SCACP executes the command string and exits.

    To access full SCACP utility help, enter HELP at the SCACP> prompt.

    SCACP> HELP

    To exit SCACP and return to the DCL command level, enter the EXIT
    command at the SCACP> prompt or press Ctrl/Z.
