system interrupt vector (SIV)
system interrupt vector (SIV). An HP NonStop™ operating system data structure that
contains the addresses of interrupt handlers, parameters passed to interrupt handlers
by special interrupt microcode, and other interrupt processing information.
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 load. (1) To start the system; to load the HP NonStop™ operating system image
into the memory of a processor. See RELOAD. (2) The process of loading the
operating system. A system load changes a system from an inactive to an active (or
operational) state by loading software that establishes communication between the
operating system and configured system peripherals.
system-managed process. Another name for a generic process.
system manager. See manager.
system number. See Expand node number.
system operator. See local operator and remote operator.
system planner. The person who plans for the hardware and software installation of a new
system or for changes to a system already installed. This person arranges for site
preparation, schedules the installation, and completes the Installation Document
Packet.
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.
system reduction. The process of making a donor system smaller by removing enclosures
from it. The enclosures removed from a donor system might be added to a target
system. Contrast with system expansion.
system resizing. See system expansion or system reduction.
