preferred path
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.
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™ Kernel 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.
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 a 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. In the Open System Services (OSS) environment, the unique identifier
representing a process group during its lifetime.
process group leader. In the Open System Services (OSS) environment, the process that
has the process group ID of its process group as its OSS process ID.
process group lifetime. In the Open System Services (OSS) environment, 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 ID. In the Guardian environment, the content of a four-integer array that uniquely
identifies a process during the lifetime of the process. See also PID
.
process identification number (PIN). A number that uniquely identifies a process running
in a processor. The same number can exist in other processors in the same system.
See also process ID
.
process image file. On a UNIX system, an executable object file. In some Guardian
product externals and end-user publications, an executable object file is referred to as
a “program file.” See also object file
