Status Configuration screen
of status configuration files; operators specify on the Profile screen which file
ViewPoint uses to display status at their terminals.
Status Configuration screen. The ViewPoint screen on which the operator can specify
configuration information to control the display of status items on the Network Status
Summary screen.
status item. A measurable condition in a system or network that is displayed on one line of a
Network Status Summary display screen. Each such item is separately chosen and
configured for display by use of the Status Item Configuration screen.
Status Item Configuration screen. The ViewPoint screen on which individual operators can
modify existing items or add new items to a status configuration file for display on their
Network Status Summary screen.
status server. A server that collects data for the ViewPoint Network Status Summary screen.
Compaq provides a default status server; the user can write and configure additional
status servers to augment or replace the functions of the default status server. Typically,
a status server issues programmatic commands to subsystems to find out how many or
how much of some resource is available—for example, how many network nodes are
available or how many terminals are up. A status server is defined to Pathway as a
server class. A status server can also be called a status collection server.
subject. In event management, a device, process, or other named entity about which a given
event message is concerned.
subsystem. A program or set of processes that manages a cohesive set of objects. Each
subsystem has a management process through which applications can request services
by issuing commands defined by that subsystem. See management process.
subsystem ID. A data structure that uniquely identifies a subsystem (including whether it is a
Tandem subsystem or a user subsystem). It consists of the name of the owner of the
subsystem (the company that provides it), a subsystem number that denotes the
subsystem within the scope of its owner, and a subsystem version number. The
subsystem ID is an argument to most of the SPI procedures.
subsystem number. An integer that identifies a subsystem within the context of its owner.
The subsystem owner, the subsystem number, and the subsystem version number make
up the subsystem ID that uniquely identifies a subsystem.
Subsystem Programmatic Interface. A common, message-based interface that can be used
to build and decode messages used for communication between requesters and servers—
for instance, in a management application. It includes procedures to build and decode
specially formatted messages (as described under “SPI message”); definition files in
TAL, COBOL, and TACL for inclusion in programs, macros, and routines using the
interface procedures; and definition files in DDL for programmers writing their own
subsystems.
token. In SPI, a distinguishable unit in an SPI message. Programs place tokens in an SPI
buffer using the SSPUT procedure (except for header tokens, which are a special case)
