process group A set of OSS processes that can signal associated processes. Each process in an Expand node
is a member of a process group; the process group has a process group ID. A new process
becomes a member of the process group of its creator.
process group ID The unique identifier representing a process group during its lifetime.
process group
leader
The process that has the process group ID of its process group as its OSS process ID.
process group
lifetime
The period that begins when a process group is created and ends when the lifetime of the last
remaining process of the group ends.
process handle An object that uniquely identifies an OSS or Guardian process within a network of HP NonStop
systems.
process ID See OSS process ID (PID).
process image file On a UNIX system, an executable object file. In some Guardian documentation, an executable
object file is referred to as a “program file.” See object file.
process lifetime The period that begins when a process is created and ends when its OSS process ID is returned
to the system for reuse.
process snapshot The contents of a saveabend file or process snapshot file.
process snapshot
file.
A file containing dump information needed by a debugging tool. In UNIX systems, such files
are usually called core files or core dump files.
1.
2. A file containing the state of a running process at a specific moment, regardless of whether
the process terminated abnormally
A snapshot file can be created by the Native Inspect SAVE command and the Visual Inspect
CREATE SNAPSHOT command.
See also save file and saveabend file.
program A loadfile that contains a main entry point.
Public Library
Installation Tool
A utility that prepares a set of public DLLs for use and that creates the public DLL registry file
(ZREG).
reentrant function A function that can safely be called while an instance of the same function is running in the same
process environment. Such functions must either avoid static or global data, or appropriately
synchronize their use.
reference page The online or hard-copy version of a file that provides reference information for a software facility.
Some UNIX documentation uses 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 manual.
regular file In the 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.
relative pathname 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.
restricted-access
fileset
A fileset that has a RESTRICTEDACCESS attribute value of ENABLED or LOCAL. A restricted-access
fileset requires the super ID to adhere to the same file permissions and owner privileges as any
other user ID.
See also fileset.
RISC instructions Register-oriented 32-bit machine instructions that are directly executed on TNS/R processors.
Reduced instruction-set computing (RISC) instructions execute only on TNS/R systems, not on TNS
or TNS/E systems.
Accelerator-generated RISC instructions are produced by accelerating TNS object code using the
Accelerator program (AXCEL). Native-compiled RISC instructions are produced by compiling
source code with a TNS/R compiler.
root See root fileset and root directory. See also super ID.
root directory A directory associated with a process that the system uses for pathname resolution when a
pathname begins with a slash (/) character.
