Subsystem Programmatic Interface. See SPI.
summary state. In DSM interfaces to Compaq data communications subsystems, one of the
generally defined possible conditions of an object, with respect to the management of
that object. A summary state differs from a state in two ways. First, a summary state
pertains only to the management of an object, whereas a state may convey other kinds of
information about the object. Second, summary states are defined the same way for all
Compaq data communications subsystems, whereas the set of possible states differs
from subsystem to subsystem. The management programming interfaces to Compaq
data communications subsystems refer to summary states rather than to states.
Examples of summary states are STARTED, STOPPED, SUSPENDED, and
ABORTING.
superobject. An object that has other objects for one or more of its attributes.
SUT (site update tape). The tape on which Compaq ships its software for installation. The
product files on the SUT tape are grouped into distribution subvolumes (DSVs), the
names of which appear on the last part of the packing list. The SUT contains the DSVs
for OSI/MHS and other products.
symbolic name. In DSM programmatic interfaces, a name used in programs to refer to
commonly used values, token codes, token maps, extensible structures, and other related
variables for use in management programs.
syntax. See attribute syntax.
Sysgen. The Compaq system generation program, used to configure objects such as devices,
controllers, and I/O processes in a newly installed system, or to update the system when
new software is released. Objects to be configured are defined to Sysgen in a special
configuration file, which can then be cold loaded into the system. The Compaq OSI
products are not configured with Sysgen, but the underlying X25AM and TLAM I/O
processes are.
T-selector. See TSEL.
TAL. The Transaction Application Language, which is used to write systems software and
routines that support transaction-oriented applications. It is also used to write
application software.
TAPS (Tandem application, presentation, and session) process. A process in the OSI/AS
subsystem that performs service and protocol functions for ACSE (in the Application
Layer), the Presentation Layer, and the Session Layer. The TAPS process also performs
some management services in the DSM environment.
