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

       /NAME_OF_MANAGER=name

    Identifies the name of the queue manager to control the queue.
    Once the queue is created, the queue manager assignment may not
    be altered.

    If the /NAME_OF_MANAGER qualifier is omitted, then the default
    name SYS$QUEUE_MANAGER is used.

    If the INITIALIZE/QUEUE command is used to modify a queue, and
    that queue is not controlled by the default queue manager, then
    the name of the controlling queue manager should be specified
    with the /NAME_OF_MANAGER qualifier. Alternately, the logical
    name SYS$QUEUE_MANAGER can be defined to be the correct queue
    manager, making that queue manager the default for the current
    process.
