Glossary
action event. An event that requires operator action to resolve. Each subsystem
determines which events are action events by including a unique EMS token in the
event message. See Event Management Service (EMS).
advice line. Line 23 (or 21 in some cases) of the VHS block-mode screens. It provides
information pertinent to your operation of VHS, such as error notices and advisory
messages (such as operation-complete messages).
alias. An alternative name for a command or a series of commands.
automated teller machine (ATM). A type of terminal used by banks for automated deposits
and withdrawals.
collector. An EMS process that accepts event messages from subsystems and logs them in
an event log. See Event Management Service (EMS).
command. A demand for action by or for information from a subsystem, or the operation
demanded by an operator or application. A command is typically conveyed as an
interprocess message from an application to a subsystem.
configuration file. A file that contains only configuration data. The ViewPoint application
has configuration files for status and for events, and there may be several of each. An
operator selects the desired configuration file by entering its name in the appropriate
field in the Profile screen. When the operator exits from the Profile screen, the data in
the named file is the new configuration for all status and event screens that are
subsequently displayed.
consumer distributor. An EMS distributor process that returns selected event messages to
management applications upon request. See Event Management Service (EMS).
Compare forwarding distributor and printing distributor.
critical event. An event designated as critical to the operation of the system or network.
Each subsystem determines which set of events generated by that subsystem should
be designated as critical. The subsystem identifies whether an event is critical or
noncritical by setting the value of the emphasis token in the event message.
Data Definition Language (DDL). A language and compiler used to define SPI token
codes, token maps, and token types and to generate a DDL definition file and
language-specific definition files; the language-specific definition files can be included
in the source code for management applications or management interfaces that use
SPI. See Subsystem Programmatic Interface (SPI).
data-portion token. A token within the body of an SPI message, as opposed to within the
header. Data-portion tokens are placed in the buffer using SSPUT or SSPUTTKN.
Some data-portion tokens can occur multiple times in the buffer, and most can be
