event
information about the error. A response record must contain a return token and can also
contain error lists to explain the error further.
event. In DSM, a significant change in some condition in the system or network. Events can
be operational errors, notifications of limits exceeded, requests for action needed, and so
on.
event log. A file or set of files maintained by EMS to store event messages generated by
subsystems.
event management. The reporting and logging of events, the distribution and retrieval of
information concerning those events, and the actions taken by operations personnel or
software in response to the events. See also control and inquiry.
Event Management Service. See EMS.
event message. A special kind of SPI message that describes an event occurring in the
system or network. See also command message or response message.
event-message template. A structured form in which to display event messages.
event messaging interface. In DSM, a management interface that reports significant events
detected by the subsystem.
exception report. In the OSI Session Layer, a report indicating that a problem has occurred
on a connection. Exception reports can be issued by applications and by the service
provider. The severity of the problem varies, as does the corrective action. In some
cases, no recovery action is needed; in others, some recovery action is required; and in
other cases, no programmatic recovery is possible. On receipt of an exception report
indication, either the local or the remote application must initiate an action to clear the
error before either application can initiate any other services.
exporter. In the Transfer X400 gateway, the server that moves messages from the Transfer
environment into the X.400 environment. See also importer.
extended processing. In the GPI, the type of operation requested of an MTA or MTS user by
means of an extension. See also extension.
extensible structure. In DSM programmatic interfaces, a structure declared for the value of
an extensible structured token. See also fixed structure.
extension. In X.400, an element of service that was defined in the 1988 recommendations but
was not present in the 1984 recommendations. Some 1988 extensions are explicitly
supported by the GPI, whereas others are not. Those that are supported are represented
by explicit attributes in the GPI. The extensions that are not explicitly supported by the
GPI are made available as BER-encoded data; GPI objects that include unsupported
extensions contain one or more instances of the MH-C-EXTENSIONS class. See also
BER.
