static translation
static translation. A TNS translation step explicitly invoked from the command line before a
TNS object file is executed. The Accelerator and the TNS Object Code Accelerator
(OCA) are static translators.
subvolume. A group of related files stored on a disk. All the files have the same volume
and subvolume name, but each file has a unique file identifier.
super ID. On HP NonStop™ systems, a privileged user who can read, write, execute, and
purge all files on the system. The super ID is usually a member of a system-supervisor
group.
The super ID has the set of special permissions called appropriate privileges. In the
Guardian environment, the structured view of the super ID, which is (255, 255), is most
commonly used. In the Open System Services (OSS) environment, the scalar view of
the super ID, which is 65535, is most commonly used.
superuser. See super ID.
SUT. See site update tape (SUT).
symbolic reference. An occurrence in code or data of the value of a symbol. The symbolic
reference is bound (resolved and made usable) by assigning to it the value of a
definition of that symbol. The symbol value is normally the address of a function or
variable named by the symbol. In position-independent code (PIC) loadfiles, symbolic
references occur only in data.
SYSnn subvolume. A subvolume on the $SYSTEM volume where the new version of the
HP NonStop™ operating system image is located. Also located on the SYSnn
subvolume is system-dependent and release version update (RVU)-dependent
software. nn is an octal number in the range %00 through %77.
system. All the processors, controllers, firmware, peripheral devices, software, and related
components that are directly connected together to form an entity that is managed by
one HP NonStop™ operating system image and operated as one computer.
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 expansion. The process of making a target system larger by adding enclosures to
it. The enclosures being added can be either new enclosures or enclosures from a
donor system. Contrast with TACL.
system generation. The process of creating an operating system to support a particular
system configuration and release version update (RVU).
