SPI procedures. In DSM, the set of operating system procedures used to build and decode
buffers for use in system and network management and in certain other applications.
These procedures are SSINIT, SSNULL, SSPUT, SSPUTTKN, SSGET, SSGETTKN,
SSMOVE, and SSMOVETKN.
SPI standard definitions. In DSM programmatic interfaces, the set of declarations available
for use with the SPI procedures, regardless of the subsystem. There is also a set of
subsystem-specific declarations for each subsystem, and some sets of declarations
that apply to multiple subsystems. See also definition and definition files, data
communications standard definitions or EMS standard definitions.
SQL. See NonStop SQL.
SSAP. A logical location between the Session and Presentation Layers, through which
session services are made available to local users, and through which presentation
services are made available to remote systems.
SSEL (session selector). An address at the boundary between the Session and
Presentation Layers, through which connections are established and maintained. A
single SSEL can service one or more connections simultaneously and can refer to one
or more SSAPs.
SSID (subsystem ID). In DSM programmatic interfaces, a data structure that uniquely
identifies a subsystem to SPI. It consists of the name of the owner of the subsystem ,
a subsystem number that identifies that particular subsystem, and a subsystem version
number. The subsystem ID is an argument to most of the SPI procedures.
string element\. The bits of a bit string or the octets of an octet string.
string segment. A portion of a string value consisting of zero or more contiguous octets of
its representation.
subject. In event management, a device, process, or other named entity about which a
given event message has information.
subnetwork. In general, a network that participates in a larger network, possibly through the
use of gateways or bridges.
In OSI, one or more intermediate systems that provide relaying and through which end
systems may establish network connections.
subobject. An object that is an attribute of another object.
SUBSYS object. An object type, used in OSI/MHS management interfaces, that identifies
the subsystem as a whole. You use the SUBSYS object to configure general aspects
of the subsystem and to inquire about the subsystem as a whole.
