RISC instructions

RISC instructions. See MIPS RISC instructions.

RISC processor. An instruction processing unit (IPU) that is based on reduced

instruction-set computing (RISC) architecture. TNS/R processors contain RISC

processors.

rld library. A library that loads position-independent code (PIC) programs and their

associated dynamic-link libraries (DLLs). The rld library also provides the dlopen(),

dlclose(), dlresultcode(), dlsys(), and dlerror() functions.

run-time linker. See linker.

run-time loader. See loader.

RVU. See release version update (RVU).

save file. A file created by the Inspect subsystem in response to a command from a

debugger. A save file contains enough information about a running process at a given

time to restart the process at the same point in its execution. A save file contains an

image of the process, data for the process, and the status of the process at the time

the save file was created.

A save file can be created through an Inspect SAVE command at any time. A save file

called a saveabend file can be created when a process’s SAVEABEND attribute is set

and the process terminates abnormally. Other debuggers can create a save file but

refer to the result as a process snapshot file. See also process snapshot file.

saveabend file. A file containing dump information needed by the system debugging tool.

(In UNIX systems, such files are usually called core files or core dump files.) A

saveabend file is a special case of a save file. See also save file and process snapshot

file.

segment. In general, a contiguous sequence of logically related pages of virtual memory.

The pages of the segment are individually swapped in and out of physical memory as

needed. Within a loadable object file, one of the portions of the file that is mapped as

one unit into virtual memory as the file is loaded. See also code segment and data

segment.

selectable segment. A type of logical segment formerly known as an extended data

segment. The data area for a selectable segment always begins with relative segment

4, and this area can be dynamically switched among several selectable segments by

calls to the Guardian SEGMENT_USE_ procedure. The effect is similar to a rapid

overlaying of one large data area. See also logical segment and flat segment.

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.
