symbolic name
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.
system services. The tasks performed on behalf of the user or user programs by the operating
system, including formatting, process control, I/O support, performance measurement,
NonStop process-pair support, standard security, and transaction management.
T-selector. See TSEL.
T.61. See teletex string.
TAL (Transaction Application Language). A programming language specific to Compaq
systems, 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.
teletex string. An extended alphabet for use in international text communication. In addition
to the standard ASCII character set, the teletex character set includes accents and
umlauts (diacritical marks) applied to Latin characters, as well as a number of special
alphabetical combinations such as IJ ligatures. The teletex character set is based on
CCITT recommendation T.61.
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
