Subsystem Control Point (SCP)
Subsystem Control Point (SCP). The management process for all Tandem data
communications subsystems.
super-ID user. A user who can read, write, execute, and purge most files on the system. A
super-ID user is usually a member of a system-supervisor group. a
SWITCH. A sensitive SCF and SPI command that causes the backup processor to become
the primary processor and the primary processor to become the backup processor.
timestamp. An identifier that indicates when a file was created or modified.
token-ring network. A network in which computers are connected in a ring-shaped layout
(topology) and in which the right to transmit data is defined by possession of a special
kind of data unit, called a token. A station that is finished transmitting or that does not
wish to transmit passes the token along to the adjacent station on the ring.
Token-Ring ServerNet adapter (TRSA). A ServerNet adapter that provides connectivity
between Himalaya S-series servers and token-ring 802.5 local area networks (LANs).
TRACE. A sensitive SCF and SPI command that requests the capture of selected data items,
alters trace parameters, and ends tracing. An SCF trace produces a trace file that can be
displayed using the commands available in the PTrace program. Use of SCF trace by a
subsystem is optional; a subsystem can supply its own tracing method.
TRSA. See Token-Ring ServerNet adapter (TRSA)
