process group ID
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 4-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.
process lifetime. The period that begins when an Open System Services (OSS) process is
created and ends when its OSS process ID is returned to the system for reuse.
PROCESS object type. In a subsystem, the object type for the subsystem manager
process itself or any generic process.
process-pair list (PPL). A table that contains one entry for each process or process pair
associated with a named resource. For some devices, a single PPL entry is associated
with multiple named resource list (NRL) entries. For process pairs, a single PPL entry
describes both members of the pair.
process snapshot. The contents of a saveabend file or process snapshot file.
process snapshot file. (1) A file containing dump information needed by the system
debugging tool. In UNIX systems, such files are usually called core files or core dump
files. (2) A file containing the state of a running process at a specific moment,
regardless of whether the process terminated abnormally. See also saveabend file.
processor. (1) A functional unit of a computer that reads program instructions, moves data
between processor memory and the input/output controllers, and performs arithmetic
operations. Because a processor is composed of several hardware components that
reside in different enclosures, it is sometimes called a logical processor. A processor is
sometimes referred to as a central processing unit (CPU), but HP NonStop™ servers
have multiple cooperating processors rather than a single CPU. (2) One or more
computer chips, typically mounted on a logic board, that are designed to perform data
processing or to manage a particular aspect of computer operations.
