DSM
DSM. See Distributed Systems Management (DSM).
Dynamic System Configuration (DSC). A facility that allows system managers to make
online changes to the configuration of devices and controllers. Its interactive utility
program is called the Configuration Utility Program (COUP)
. DSC is not used to
configure Tandem OSI subsystem objects, but it can be used to configure the underlying
X.25 Access Method (X25AM) and Tandem LAN Access Method (TLAM) objects.
EMS. See Event Management Service (EMS)
.
end system. A host or user machine that contains all seven Open Systems Interconnection
(OSI) layers. An end system can communicate with another end system either directly or
through one or more intervening intermediate systems. Tandem systems function as end
systems only. See also intermediate system
.
entry. A type of object representing a routing table or directory entry in the Management
Information Base (MIB).
event. In Distributed Systems Management (DSM)
terms, 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 Management Service (EMS). A part of Distributed Systems Management (DSM)
used to provide event collection, event logging, and event distribution facilities. EMS
has a programmatic interface based on the Subsystem Programmatic Interface (SPI) for
both reporting and retrieving events.
flow control. A function that regulates the flow of data within a layer or between adjacent
layers.
global network address. See network service access point (NSAP)
and network service
access point (NSAP) address.
header. The initial part of an Event Management Service (EMS)
message.
header token. In an Event Management Service (EMS)
message, a token that provides
information pertaining to the message as a whole.
indirect-process-name. Form of a process name that directs the command through the Open
Systems Interconnection (OSI) manager process first, then on to the specified process
type, allowing the Management Information Base (MIB)
to be updated.
