subject
structured tokens are extensible structured tokens. See structure, simple token, and
extensible structured token
.
subject. In event management, a device, process, or other named entity about which a
given event message is concerned.
subordinate names option. In extended SPI subsystems, the designation that the object
name given in the command stands not just for itself, but for the names of all objects at
the next-lower level in a hierarchy. (The given object name can stand both for itself and
for the subordinate objects, or it can stand only for the subordinate objects, depending
on the value of the SUB token.) When this option is present in a command, the
subordinate names are implied even though they are not given explicitly.
subsystem. A program or set of processes that manages a cohesive set of objects. Each
subsystem has a manager process (in some cases, this process is the entire
subsystem) through which applications can request services by issuing commands
defined by that subsystem. See manager process
.
Subsystem Control Facility. The interactive interface for configuring, controlling, and
collecting information from NonStop Kernel subsystems. The Subsystem Control
Facility provides many of the same functions as CMI, CUP, and PUP, plus additional
functions not available in CMI, CUP, or PUP.
Subsystem Control Point. An intermediate management process used by many NonStop
Kernel subsystems. There can be several instances of this process. Applications send
commands to an instance of this process, which in turn sends them on to the manager
processes of the target subsystem. The Subsystem Control Point also processes a few
commands itself. It provides security features, version compatibility, support for tracing,
and support for applications implemented as process pairs.
subsystem definitions. The set of declarations available for use with a particular
subsystem that supports a token-oriented programmatic interface. See also definition
files and SPI standard definitions.
subsystem ID. A data structure that uniquely identifies a subsystem (including whether it is
a NonStop Kernel subsystem or a subsystem you write). 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 owner. A value identifying the company that supplies a particular subsystem. It
consists of a name of up to eight characters, blank-filled on the right. For example, the
owner for all subsystems supplied by HP is “TANDEMbb
”. The subsystem owner, the
subsystem number, and the subsystem version number make up the subsystem ID
that uniquely identifies the subsystem.
