Glossary
filter. A file that contains a list of criteria against which incoming event messages can be
compared so as to pass a given message (if it meets all criteria) or not pass it (if it fails
one or more criteria).
filter object file. A file containing the compiled filter code that determines which events are
displayed on an events screen.
high PIN (process identification number). A PIN that is greater than 255. See also low PIN.
historical mode. A view of event messages that has a specified starting time (or date and
time) and a finite ending time, usually determined by the size of an event cache. If no
starting time is specified, the view is one of current events rather than historical events.
last event. A recent event that concerns a particular object. When requested, ViewPoint
displays on the Last Events screen a page of last-event messages whose subject is a
selected object.
Last Events screen. The screen on which ViewPoint displays all events with a particular
subject.
low PIN (process identification number). A PIN that is ranges from 0 to 254. See also high
PIN.
macro. A sequence of TACL commands and built-in functions that can contain dummy
arguments, thus providing a means for simple argument substitution. No validity
checking of the arguments is performed. When the macro name is given to TACL, TACL
substitutes the expansion of the command sequence for the name, replacing any dummy
arguments with parameter values supplied in the invocation.
management application. A program or set of programs that issues commands to
subsystems and/or retrieves event messages to assist in managing a computer system or
a network of systems. A management application is a requester with respect to the
subsystems to which it sends commands; the subsystems are servers with respect to the
management application.
management process. The process through which an application issues commands to a
subsystem. A management process can be associated with more than one subsystem; in
this case, the management process is logically part of each of the subsystems. The
Subsystem Control Point (SCP) and PATHMON are examples of management
processes.
message. A block of information, usually in the form of a structure, that is sent from one
process to another. See also SPI message.
Network Control Node (NCN). In the context of the ViewPoint application, a node (one
Tandem system) where the ViewPoint terminal control process (TCP) is running. Since
it is possible to have more than one such process in a network, there can likewise be
more than one NCN in a network of Tandem systems.
