System Code (SC)
System Code (SC). See TNS code space.
system code. A logically distinct part of the HP NonStop™ operating system that consists
of operating system procedures shared by all processors.
system entry-point (SEP) table. A table used on TNS systems that stores the XEP entry
value for each TNS operating system procedure entry point.
system generation. The process of creating an operating system to support a particular
system configuration and release version update (RVU).
System Library (SL). See TNS code space.
system library. A logically distinct part of the HP NonStop™ operating system that consists
of user-callable library procedures and kernel procedures.
system process. (1) A privileged process that comes into existence at system-load time
and exists continuously for a given configuration for as long as the processor remains
operable. (2) An HP NonStop™ operating system process, such as the memory
manager, the monitor, and the input/output (I/O) control processes. The files containing
system processes are invoked by ALLPROCESSORS paragraph entries. (3) A part of
a single copy of the HP NonStop operating system with Open System Services (OSS)
interfaces. A system process does not have an OSS process ID.
TACL. See HP Tandem Advanced Command Language (TACL).
TAL. See HP Transaction Application Language (TAL).
temporary disk file. A file stored on disk that will be purged automatically as soon as the
process that created it stops.
TIM. See HP NonStop™ Technical Library (NTL).
TNS. Refers to fault-tolerant HP computers that support the HP NonStop™ operating
system and are based on microcoded complex instruction-set computing (CISC)
technology. TNS systems run the TNS instruction set. Contrast with TNS/R and
TNS/E.
TNS accelerated mode. A TNS emulation environment on a TNS/R or TNS/E system in
which accelerated TNS object files are run. TNS instructions have been previously
translated into optimized sequences of MIPS or Intel® Itanium® instructions. TNS
accelerated mode runs much faster than TNS interpreted mode. Accelerated or
interpreted TNS object code cannot be mixed with or called by native mode object
code. See also TNS Object Code Accelerator (OCA)
. Contrast with TNS/R native
mode and TNS/E native mode.
TNS C compiler. The C compiler that generates TNS object files. Contrast with TNS/E
native compiler.
