Glossary
This glossary defines terms used in this manual and in related manuals for Distributed
Systems Management.
action command. A command that results in action on an object, as opposed to retrieval of
information. See also information command.
action event. An event that requires operator action to resolve. Each subsystem
determines what events are action events by including a unique EMS token in the
event message. Events designated as action events are reported in pairs of event
messages: an action-attention message to report the problem, and an action-
completion message to report that the appropriate operator action has been taken.
attribute. A characteristic of an entity. For example, two attributes of a DNS alias are an
alias type and domain. Two attributes of a communications line might be its baud rate
and its retry count. In a token-oriented interface based on SPI, an attribute of an object
is usually expressed as a simple token or a field within an extensible structured token.
The attributes of a token are its length, count, address, and offset. Programs can
obtain these attributes through special SSGET operations.
attribute token. A parameter or response token that represents one or more characteristics
of an object.
buffer. A sequence of memory locations used for temporary storage of data. For instance,
data to be sent in an interprocess message is encoded in a buffer from which it is
copied by the file system. The data is delivered to a buffer addressable by the
recipient. See also message buffer and SPI buffer.
built-in. A primitive function or variable in TACL. Names of built-ins always begin with a
pound sign (#).
clipboard file. An EDIT file to which an operator can copy selected lines from a
VIEWPOINT display screen. The operator, or a management application program, can
then access the selected lines of text in that file at some later time. Copying to the
clipboard file is termed clipping.
collector. An Event Management Service (EMS) process that accepts event messages
from subsystems and logs them in the event log. See also distributor
.
command. A demand for action by or 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.
command message. A SPI message, containing a command, that is sent from an
application program to a subsystem. See SPI message.
