/sys$common/syshlp/helplib.hlb DISABLE, AUTOSTART, Qualifiers, /NAME_OF_MANAGER  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /NAME_OF_MANAGER=name

    Specifies the name of the queue manager controlling the autostart
    queues you want to disable. The qualifier allows the autostart
    feature to be used differently for different sets of queues.

    If the /NAME_OF_MANAGER qualifier is omitted, the default queue
    manager name SYS$QUEUE_MANAGER is used. For more information on
    multiple queue managers, refer to the OpenVMS System Manager's
    Manual.
