primary path
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.
private dynamic-link library (private DLL). See ordinary dynamic-link library (ordinary 
DLL).
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 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 code file.
