PPP
PPP. See Point-to-Point Protocol (PPP).
preemption. A form of late binding in which a symbolic reference to a symbol defined in the
same dynamic-link library is instead bound to a definition in another loadfile.
preferences file. A file that contains configuration information for the graphical user
interface (GUI) portion of the OSM and TSM client software. The preferences file is
used by the OSM and TSM client software at system startup.
preferred path. See primary path.
preprocessing commands. Commands specifying unique run-time parameters that can
override your default system parameters. These commands can assign process file
names, select backup media formats, and define utility options during system
configuration.
preset. A linker operation that sets the correct values (addresses) of imported symbols
according to the environment seen by the linker. If the loader encounters the same
environment at load time, it avoids adjusting these values, which reduces loading
overhead. (See
fastLoad.) If not, the loader resets these values to match the load-time
environment.
primary path. A path enabled as the preferred path. When a primary path is disabled, an
alternate path
becomes the primary path.
primary processor. The processor that is designated as owning the ServerNet addressable
controller (SAC) connected to separate processors running the HP NonStop™
operating system. The primary processor is the processor that has direct control over
the SAC. Contrast with backup processor
.
problem incident report. A type of incident report that reports a problem in the server. A
problem incident report is generated when changes occur on the server that could
directly affect the availability of system resources.
procedure entry-point (PEP) table. A table in a TNS object file that contains the entry-
point addresses for each procedure and is located in the first page of each code
segment.
process. (1) A program that has been submitted to the operating system for execution, or a
program that is currently running in the computer. (2) An address space, a single
thread of control that executes within that address space, and the system resources
required by that thread of control.
process group. In the Open System Services (OSS) environment, a set of 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.
