superobject
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 (Compaq 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.
terminal O/R address. An O/R address that identifies a user by a network address and, if
required, a terminal type.
TLAM (Tandem LAN access method). A Compaq product that implements the services of
the Data Link and Physical Layers for LANs.
TMF (Transaction Management Facility). A data management product that maintains the
consistency of a database and provides the tools for database recovery.
token. In DSM, a distinguishable unit in an SPI message. Programs place tokens in an SPI
buffer using the SSPUT or SSINIT procedures and retrieve them from the buffer using
the SSGET procedure. A token has two parts: an identifying code, or token code, and a
token value. In command and response messages, a token normally represents a
parameter to a command, an item of information in a response, or control information
