Glossary-1
Glossary
The following glossary defines terms used in this manual and in the other Compaq OSI
product manuals. Not all terms listed here are used in this particular manual.
action event. An event that requires operator intervention. Each subsystem determines which
events are action events by including a unique Event Management Service (EMS)
token
in the event message. Action events are reported as pairs of event messages: an action-
attention message to report the problem and an action-completion message to report the
problem resolution.
adapter. See ServerNet adapter
.
address sharing. The use of multiple addresses on the same physical connection.
Application Layer. Layer 7 of the Open Systems Interconnection (OSI) Reference Model
.
This layer provides the interface between user programs (application processes) and the
OSI network. Layer 7 includes the standards for services such as file transfer, electronic
mail, and terminal access. OSI/FTAM
is an example of an application that uses the
Application Layer.
application name. The address by which an application entity is known to the local
subsystem. Application names are defined locally only.
Association. A connection between Application Layer
entities.
called address. The address to which a connect request is addressed.
called user. The application to which a calling user requests a connection.
calling address. The address from which a connect request is initiated.
calling user. The application that initiates a request to establish a connection.
collector. An Event Management Service (EMS)
process that accepts event messages from
subsystems and logs them in the event log. See also distributor.
compatibility distributor. An Event Management Service (EMS)
distributor process that
filters event messages according to fixed (rather than user-specified) criteria, obtains
text for these messages, and writes the text to the console-message destinations.
Configuration Utility Program (COUP). An interactive program that allows system
managers to make online changes to the configuration of devices and controllers. COUP
is part of the Dynamic System Configuration (DSC)
facility, which is not used to
configure Compaq OSI subsystem objects, but which can be used to configure the
underlying ViewPoint and Tandem LAN Access Method (TLAM) objects.
