 dirspec

    Specifies the directory location to contain the system queue and
    journal files of the queue database. The queue file has a file
    type of QMAN$QUEUES and contains queue definitions. The journal
    file has a file type of QMAN$JOURNAL and contains job and other
    information that lets the queue manager to return to its last
    known state should a system be stopped unexpectedly. These files
    must reside in the same directory.

    The default location of the queue and journal files is
    SYS$COMMON:[SYSEXE]. The optional dirspec parameter is used
    only for specifying an alternate location for the queue and
    journal files. The specification must include at least the
    device and directory name. The asterisk (*)  and the percent
    sign (%)  wildcard characters are not allowed in the directory
    specification.

    The directory you specify must be available to all nodes that
    can run the queue manager. If the directory specification is a
    concealed logical name, it must be identically defined on all
    nodes in the cluster.

    The location of the queue and journal files is stored in the
    master file of the queue database. You do not have to respecify
    the directory location with subsequent START/QUEUE/MANAGER
    commands.

    For information about changing the location of any of the queue
    database files, refer to the Guide to Maintaining a VMS System.
