NonStop System Glossary

register-exact point
A synchronization location within an accelerated object file at which both of these statements are
true:
• All live TNS registers plus all values in memory are the same as they would be if the object
file were running in TNS mode or TNS interpreted mode or on a TNS system.
• All accelerator code optimizations are ended.
Register-exact points are a small subset of all memory-exact points. Procedure entry and exit
locations and call-return sites are usually register-exact points. All places where the program might
switch into or from TNS mode or TNS interpreted mode are register-exact points. Contrast with
memory-exact point and nonexact point.
register pointer (RP)
The register pointer in TNS computers.
regular file
In the Open System Services (OSS) file system, a file that is a randomly accessible sequence of
bytes. A regular file contains binary or text data and has no structure imposed by the system.
Contrast with special file.
reintegration
When a processor element has diverged or has been added or replaced, memory is copied from
a functioning NonStop Blade Element to the replaced or added NonStop Blade Element, and the
processor element is reintegrated into the logical processor.
reintegration board
The part of a NonStop Blade Element that contains the hardware used in memory copy operations.
relative pathname
In the Open System Services (OSS) file system and Network File System (NFS), a pathname that
does not begin with a slash (/) character. A relative pathname is resolved beginning with the
current working directory. Contrast with absolute pathname.
release version update (RVU)
A collection of compatible revisions of NonStop operating system software products, identified by
an RVU ID, and shipped and supported as a unit. An RVU consists of the object modules, supporting
files, and documentation for the product revisions. An RVU also includes a set of documentation
for the overall RVU.
RELOAD
A TACL command to load the NonStop operating system image from disk over the ServerNet
fabrics into the memory of the processor.
remote access
A form of remote support, configured in the Notification Director for OSM and TSM. Remote access,
or dial-in, allows a service provider to dial in to your system console and access your NonStop
server to diagnose hardware and software problems. See also remote notification.
remote interprocessor communication (RIPC)
The exchange of messages between processors in different systems or nodes.
