definition
definition. A declaration provided by Compaq for use in applications that use a specific
procedural interface, such as the APS or SPI procedures. Definitions are commonly
provided in definition files.
definition files. A set of files containing declarations for use in applications that use a
specific procedural interface.
In the case of the Subsystem Programmatic Interface (SPI), there is a standard definition
file in Data Definition Language (DDL) and a definition file for each of the
programming languages supporting SPI; the latter files are derived from the DDL
definition file. Likewise, each subsystem that has a token-oriented programmatic
interface has one definition file for DDL and one for each programming language.
Some subsystems—for instance, data communications subsystems—have additional,
shared definition files. See also SPI standard definitions, data communications standard
definitions, or EMS standard definitions.
delivery report. A communication directed by an MTA toward the originator of a message,
indicating when the message was delivered to each recipient UA, as well as other
information, such as when the message arrived in each management domain through
which it passed on the way to its destination. See also nondelivery report.
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.
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.
