symbolic reference
contains a pathname and can be used to point to a file in another fileset. Symbolic
links are not included in ISO/IEC IS 9945-1:1990. Contrast with hard link.
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.
symbols region. See Inspect region.
SYSGENR. The system generation program that generates a customized version of the HP
NonStop™ Kernel operating system.
SYSnn subvolume. A subvolume on the $SYSTEM volume where the new version of the
HP NonStop™ Kernel 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.
SYSPOOL. The system data space that remains in memory after all system data structures
are built by the HP NonStop™ Kernel operating system at the time of a processor load.
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™ Kernel operating system image and operated as one computer.
See also node.
system area network management process. See external system area network manager
process (SANMAN).
System Code (SC). See TNS code space.
system code. A logically distinct part of the HP NonStop™ Kernel operating system that
consists of operating-system procedures shared by all processors.
system configuration database. The database file on the $SYSTEM.ZSYSCONF
subvolume that contains configuration information for all system objects that can be
configured by the Subsystem Control Facility (SCF). Configuration information for all
system objects that can be configured during system generation is contained on the
$SYSTEM.SYSnn subvolume. See also configuration file and SYSnn subvolume.
system console. An HP-approved personal computer used to run maintenance and
diagnostic software for HP NonStop S-series servers. New system consoles are
preconfigured with the required HP and third-party software. When upgrading to the
latest RVU, software upgrades can be installed from the HP NonStop System Console
Installer CD. System consoles communicate with NonStop S-series servers over a
dedicated local area network (LAN) or a nondedicated (public) LAN. System consoles
configured as the primary and backup dial-out points are referred to as the primary and
backup system consoles, respectively.
