external tracing
external tracing. The recording of actions taken by a management domain with respect to a
message, probe, or report. See also internal tracing.
extensible structured token. In DSM programmatic interfaces, a token consisting of a token
code and a value that is an extensible structure. Extensible structures can be extended
by adding new fields at the end. Such structures are typically used to indicate the
attributes of an object being operated on and to return status and statistics information in
responses; they can also be used for other purposes. The token is referenced by a token
map that describes the structure to SPI so that SPI can provide compatibility between
different versions of the structure. See also simple token.
file number. An integer that represents a particular instance of an open of a file. A file
number is returned by an OPEN procedure and is used in subsequent I/O procedures to
access the file.
filter. In EMS, a file containing a list of criteria against which incoming event messages can
be evaluated to see if they can pass (all criteria met) or not pass (one or more criteria
failed) through the filter.
fixed structure. In DSM programmatic interfaces, a multifield structure declared for the
value of a simple token. Fields cannot be added to fixed structures. See also extensible
structure.
forwarded IPM. An interpersonal message that is enclosed in and being forwarded by
another interpersonal message.
forwarding IPM. An interpersonal message that encloses another interpersonal message,
which is being forwarded.
fully qualified file name. A file specification that includes the volume, subvolume, and file
name ($vol.subvol.filename), possibly preceded by a system name (\system).
gateway. In general, a device or program that connects dissimilar networks at any layer
above the Network Layer, compensating for protocol differences between the networks.
In X.400, a program that integrates a proprietary messaging system with an X.400
network. For example, the GPI and its client together form a gateway.
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.
