communication. The transfer of information between or among different entities, or the
information transmitted. In GPI manuals, this term is used to designate a message, a
probe, or a report in statements that apply to all three of these types of X.400 messages.
conditional token. In DSM event management, a token that is sometimes, but not always,
present in a particular event message. See also unconditional token.
configuration and control components. The OSI/MHS components (such as the MHS
manager and configuration databases) and related products (such as SCF) that
specifically support management of the OSI/MHS subsystem.
configuration database. An OSI/MHS database that consists of the following databases:
subsystem, class, group, process, local MTA and MTA identity, entry, OSI address, MS
configuration, and RTS configuration.
configuration database subvolume. The subvolume that contains the OSI/MHS
configuration database. The default location is the same subvolume as the executable
object file for the MHS manager This subvolume contains a set of Enscribe files. The
files are protected by TMF auditing. The file names are prefixed with the first four
characters of the process name of the MHS manager.
configuration file. An SCF command file that contains all the configuration information
about one subsystem. See also OSI/MHS subsystem.
configured object. An object whose characteristics have been defined to OSI/MHS through
SCF or a management application. See also nonconfigured object.
confirm primitive. In OSI, a primitive issued when a service user is to be informed about its
request. This is one of four types of service primitives. See also service primitive.
connection. In OSI, a relationship between a service access point on one protocol stack and a
corresponding point on a different protocol stack in the desired system (this could be the
same system, or another local or remote system). See also association.
content. One of two basic parts of a message or report, containing the information to be
conveyed to the recipients. The other part is called the “envelope.” Probes contain a
description of the content rather than the content itself.
context token. In DSM programmatic interfaces, a token in an SPI response message that
indicates (by its presence or absence) whether or not the response is continued in the
following message.
control and inquiry. In DSM, those operations that affect or request information about the
state or configuration of an object. See also event management.
core services. The portion of the operating system that consists of the low-level functions,
including interprocess communication, I/O interface procedures, and memory, time, and
process management.
correspondent. A sender or receiver of information within the Transfer subsystem. Examples
of possible types of correspondents are a person, an interest group, a process, or a
device.
