Guardian
Guardian. An environment available for interactive or programmatic use with the NonStop
Kernel operating system. Processes that run in the Guardian environment use the
Guardian system procedure calls as their application program interface; interactive
users of the Guardian environment use the TACL or another HP product’s command
interpreter.
identifier. A unique name, for example, TANDEM^FILES^TO^COPY, in the CONFTEXT file
that refers to a text string (one or more file names as given in the CONFAUX file).
When SYSGENR encounters an identifier, it substitutes the text string for the identifier.
interim product modification (IPM). The method of releasing incremental software
updates on NonStop S-series systems. An IPM can include one or more corrections to
code or it can contain code that adds new function to a software product.
IPM. See interim product modification (IPM).
load. (1) To transfer the NonStop Kernel operating system image or a program from disk
into a computer’s memory so that the operating system or program can run. (2) To
insert a tape into a tape drive, which prepares it for a tape operation (read or write).
microcode. Any machine code or data that can run in a microprocessor. HP produces two
types of microcode for NonStop S-series systems: volatile and nonvolatile. Volatile
microcode is loaded into the volatile random-access memory (RAM) of some types of
printed wiring assemblies (PWAs) and is not retained in a host PWA when power to the
PWA is interrupted. See also millicode.
millicode. RISC instructions that implement various TNS low-level functions such as
exception handling, real-time translation routines, and library routines that implement
the TNS instruction set. Millicode is functionally equivalent to TNS microcode. See also
microcode.
native link editor. See nld utility.
native mode. See TNS/R native mode
.
nld utility. (1) The utility that collects, links, and modifies code and data blocks from one or
more object files to produce a target TNS/R native object file. The nld utility is similar
to the Binder program used in the TNS development environment. (2) The native link
editor invoked by SYSGENR to build the TSYSCLR and TSYSDP2 files.
object file. A file generated by a compiler, Binder program, or nld utility that contains
machine instructions and other information needed to construct the executable code
spaces and initial data for a process. The file might be a complete program that is
ready for immediate execution, or it might be incomplete and require linking with other
object files before execution.
offline configuration. Configuration performed offline by SYSGENR. If necessary, you edit
the CONFTEXT configuration file to create a new configuration and then run the
