SCF. See Subsystem Control Facility (SCF).
server. (1) An implementation of a system used as a stand-alone system or as a node in an
Expand network. (2) A combination of hardware and software designed to provide
services in response to requests received from clients across a network. For example,
HP NonStop™ servers provide transaction processing, database access, and other
services. (3) A process or program that provides services to a client or a requester.
Servers are designed to receive request messages from clients or requesters; perform
the desired operations, such as database inquiries or updates, security verifications,
numerical calculations, or data routing to other computer systems; and return reply
messages to the clients or requesters. A server process is a running instance of a
server program.
server application. An application that provides a service to a client application. An
application that provides local execution of remote procedure calls is an example of a
server application.
service provider. (1) A person trained and qualified to service field-replaceable units
(FRUs). (2) An organization, such as the Global Customer Support Center (GCSC),
that helps you resolve problems with your HP NonStop™ server. OSM allows you to
use the help of a service provider by configuring client software to support remote
notification and remote access.
shutdown file. A file invoked by the local operator or by another shutdown file that contains
commands to shut down system devices, communications lines, and system and
application software. Contrast with startup file.
simplex. See SMR.
single-modular redundancy (SMR). See SMR.
slice. See HP NonStop™ Blade Element (NSBE).
SMR. Single-Modular Redundancy. A degraded processor configuration involving only one
active NSBE. Also called simplex.
software product revision (SPR). The method of releasing incremental software updates
on HP NonStop™ S-series systems. An SPR can include one or more corrections to
code, or it can contain code that adds new function to a software product.
SPR. See software product revision (SPR).
startup file. A file invoked by the local operator or by another startup file that contains
commands to start up system devices, communications lines, and system and
application software. Contrast with shutdown file.
subsystem. (1) A secondary or subordinate system, usually capable of operating
independently of or asynchronously with a controlling system. (2) A program or set of
processes that manages a cohesive set of Subsystem Control Facility (SCF) objects.
