diagnostic code
diagnostic code. A value indicating why a message was not delivered (called a non-delivery-
diagnostic code in the X.411 standard).
Distributed Systems Management. See DSM.
distribution list. A list of users to whom it is possible to address messages collectively. The
distribution list name logically represents the names of all members of the list.
OSI/MHS and Transfer both support distribution lists.
distributor. An EMS process that distributes event messages from event logs to requesting
management applications, to Guardian 90 console message destinations, or to a collector
on another node. See also compatibility distributor, printing distributor, or collector.
DLIST object. An object type, used in OSI/MHS management interfaces, that identifies a
local distribution list within the Compaq OSI/MHS subsystem.
DLISTMEMBER object. An object type, used in OSI/MHS management interfaces, that
identifies an individual member of a local distribution list.
domain. A collection of nodes on an X.400 network; these are connected through MTAs.
There are two types of domains: ADMDs and PRMDs.
DSM (Distributed Systems Management). A set of tools used to manage Compaq NonStop
systems and Expand networks. These tools include the ViewPoint console application
and various other applications, the Subsystem Control Facility (SCF) for data
communications subsystems, the Subsystem Programmatic Interface (SPI), the Event
Management Service (EMS), the Distributed Name Service (DNS), and management
programming interfaces for various Compaq subsystems.
DSV (distribution subvolume). The grouping in which Compaq releases software for
installation. Names are in the form Yxxxxzzz, where xxxx is the product number
and zzz is the release number—for instance, Y9110C20. See also ISV.
EDI forwarding. The onward transfer of a received EDIM to one or more recipients
determined by a forwarding EDI-UA, EDI-MS, or PDAU. The EDIM is forwarded
along with EDI notification requests contained within it. Any of the body parts within
the EDIM can be removed (wholly, not partially) when forwarding, with the exception
of a forwarded body part, which cannot be removed. Body parts that are removed when
forwarding are replaced with placeholders to indicate which type of body part was
removed. Note that the heading of an EDIM cannot be removed when forwarding.
EDI interchange. A trade document (such as a purchase order or an invoice) in interchange
format. Currently, three formats are used widely: EDIFACT, ANSI12, and UNTDI. Of
these formats, EDIFACT is generally accepted worldwide as the
de facto standard.
EDI messaging system (EDIMS). The means by which EDI messaging users communicate
with one another. The EDIMS can be viewed as consisting of functional objects that
interact. The central object, or core, of the EDIMS is the X.400 message transfer system
(MTS). The EDIMS uses MTS as an infrastructure for exchange of EDIMs. Each
