server application

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.

(system) in a ServerNet cluster must have one SNETMON process pair running.

shared memory. An interprocess communication mechanism that allows two or more

processes to share a given region of memory.

Shared Millicode Library. An intrinsic library containing privileged or TNS-derived millicode

routines used by many native-compiled programs and by emulated TNS programs.

This library includes efficient string-move operations, TNS floating-point emulation, and

various privileged-only operations. These routines are mode independent. They

comply with native calling conventions but can be directly invoked from any mode

without changing execution modes.

shared run-time library (SRL). A collection of procedures whose code and data can be

loaded and executed only at a specific assigned virtual memory address (the same

address in all processes). SRLs use direct addressing and do not have run-time

resolution of links to and from the main program and other independent libraries.

Contrast with dynamic-link library (DLL). See also TNS shared run-time library (TNS

SRL) and TNS/R native shared run-time library (TNS/R native SRL).

shell generator. A software tool that, given a procedure interface definition coded in pTAL

for a native-mode library procedure, produces a custom shell routine to provide access

from TNS object code to that native-mode procedure. See also TNS to native-mode

access shell.

shell map. An address table created by the HP NonStop™ operating system that contains

the entry point addresses of all available TNS to native-mode access shells. See also

TNS to native-mode access shell.

site update tape (SUT). One or more tapes that contain each target system’s site-specific

subvolume and various products. Each product contains a softdoc and a complete set

of files. A SUT is delivered with every new HP NonStop™ system and can be ordered

whenever a new release version update (RVU) of the system software is available. A

full SUT contains the current RVU of the HP NonStop operating system and all product

software that has been ordered with it. A partial SUT contains a subset of products for

the current RVU.

SRL. See shared run-time library (SRL).
