Glossary-11
GATEWAY object. An object type, used in OSI/MHS management interfaces, that defines
and controls the Transfer X400 gateway or a gateway application based on the
Gateway Programmatic Interface (GPI).
GI (gateway interface) class. The OSI/MHS CLASS object that identifies the set of all GI
groups in an OSI/MHS subsystem.
GIP (Gateway Interface Process) . The server that moves messages between a
proprietary message system and OSI/MHS. An application, or “client” uses the GPI
library for access to the GIP.
GPI (Gateway Programmatic Interface). A service that provides X.400 access to
proprietary messaging systems through OSI/MHS.
GPI library. The GPI procedural interface.
GPI service. The combined function of the GPI library and the GIP.
group. A collection of one or more processes and databases that provide a defined set of
services.
GROUP object. An object type, used in OSI/MHS management interfaces, that identifies a
set of related processes and databases: for instance, a message relay process
(MRP), a reliable transfer service (RTS) process, a PDU store, and a store cleaner
(SC) process. You use a GROUP object to configure, stop, and start the set of
processes as a unit.
Guardian. The original application program interface (API) to the NonStop Kernel.
Guardian environment. The Guardian API and the NonStop tools.
header. The initial part of a message, which typically contains descriptive information
pertinent to the message as a whole and also possibly control information. In SPI, see
also header token.
header token. In an SPI message, a token that provides information pertaining to the
message as a whole. Examples of header tokens for commands are the command
number, the object type, the maximum-response token, the server-version token, the
maximum-field-version token, and the checksum token. Command and response
messages contain a specified set of header tokens; event messages, a different set
with some overlap. See also SPI message.
importer. In the Transfer X400 gateway, the server that moves messages from the X.400
network into the Transfer environment. See also exporter.
inbound communication. A communication received from the X.400 network and available
to a client. See also outbound communication.
