process group lifetime
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.

process ID .
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.
program. See program file .
program file. An executable object code file containing a program’s main routine plus
related routines statically linked together and combined into the same object file. Other
routines shared with other programs might be located in separately loaded libraries. A
program file can be named on a RUN command; other code files cannot. See also
object code file .
pTAL. Portable Transaction Application Language. A machine-independent system
programming language based on Transaction Application Language (TAL). The pTAL
language excludes architecture-specific TAL constructs and includes new constructs
that replace the architecture-specific constructs. Contrast with HP Transaction
Application Language (TAL).
pTAL compiler. An optimizing native-mode compiler for the pTAL language.
public dynamic-link library (public DLL). Optional native-mode executable code modules
available to all native user processes. A TNS/E public library is specified in the public
library registry, supplied by HP or optionally a user.
public library. A dynamic-link library (DLL) or shared run-time library (SRL) that is known to
the operating system, available for execution by any process or user, and is not an
implicit library.
public shared run-time library (public SRL). A TNS/R library supplied by HP.
$RECEIVE. The name of a file through which a process receives and optionally replies to
messages from other processes.
