Subsystem Control Point (SCP).
Subsystem Control Point (SCP). The management process for all Tandem data
communications subsystems. There can be several instances of this process.
Applications using the Subsystem Programmatic Interface (SPI) send all commands for
data communications subsystems to an instance of this process, which in turn sends the
commands on to the manager processes of the target subsystems. SCP also processes a
few commands itself. It provides security features, version compatibility, support for
tracing, and support for applications implemented as NonStop process pairs. See also
management process; manager process.
Subsystem Programmatic Interface (SPI). A set of procedures for building and decoding
commands, responses, and event messages.
super-group user (255, n). A user ID that allows users to execute some potentially
destructive commands. The super-group user is provided for operators who perform
system operations tasks, such as controlling the status of peripherals and other system
components.
super ID (255,255). A user ID that allows users to do anything on the system. Users with the
super ID can access all data and devices.
support area. The area where the operations staff is located.
SUT. See site update tape (SUT).
SYSGEN. A utility program used by DSM/SCM to generate a Tandem NonStop Series
(TNS) operating-system image for a given hardware and software configuration on
Tandem CISC systems.
SYSGENR. A utility program used by DSM/SCM to generate a Tandem NonStop
Series/RISC (TNS/R) operating-system image for a given hardware and software
configuration on Tandem RISC systems.
TACL. See Tandem Advanced Command Language (TACL).
Tandem Advanced Command Language (TACL). A powerful, extended command
interpreter for the Tandem NonStop Kernel operating system that enables you to perform
work on NonStop systems.
Tandem Capacity Model (TCM). A Tandem product that provides computer-assisted
capacity planning. It uses the Microsoft Excel spreadsheet with Measure data to explore
different growth scenarios and system configurations.
Tandem Failure Data System (TFDS). A component of the Tandem NonStop Kernel. This
tool isolates software problems and provides automatic processor failure data collection,
diagnosis, and recovery services.
Tandem Information Manager. The Tandem Information Manager (TIM) product integrates
multiple collections of Tandem product and support information—including customer
manuals, education course information, and other technical documents—to provide a
single, searchable library. The TIM viewer provides the interface to collections of
