reconfiguration
reconfiguration. The act of changing the hardware or software configuration of a running
system. Examples include installing a new software release version update (RVU),
adding hardware peripherals, and restructuring a database. Reconfiguring a system
might or might not require a planned outage.
reduced instruction-set computing (RISC). A processor architecture based on a relatively
small and simple instruction set, a large number of general-purpose registers, and an
optimized instruction pipeline that supports high-performance instruction execution.
Contrast with complex instruction-set computing (CISC).
reexported library. A library whose symbols are made available by another dynamic-link
library (DLL) to any localized client of that DLL. Reexport is an attribute of the DLL’s
libList entry for that library. This attribute is specified by the DLL’s programmer and
recorded by the linker as a DLL is built. It affects only localized clients of the DLL. This
feature allows a symbol to be moved from one DLL to another without relinking clients
of the original DLL.
Reexporting is transitive; that is, if A reexports B and B reexports C, then A reexports
C. Reexported libraries can reexport other libraries to form a succession of reexported
libraries of arbitrary length.
reference page. In Open System Services (OSS) and Distributed Computing Environment
(DCE), the online or hard-copy version of a file that provides reference information for
a software facility. Some UNIX product externals and end-user publications use the
term man page instead, referring either to the online delivery mechanism used to
display the file (usually the shell man command) or to the nature of the file as part of a
publication.
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.
requester missed address file (RMAF). A file used by the HP NonStop™ operating
system during memory-caching operations.
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.
