POET
compiler, the compiler produces a code file named POBJCOD, a directory file named
POBJDIR, and (if the SYMBOLS option is enabled) a symbols file named POBJSYM.
POET. See Pathway Open Environment Toolkit (POET).
primary process. The currently active process of a process pair in the Guardian
environment. See also backup process and process pair.
process. (1) A unique execution of a program in the Guardian environment. (2) An entity in
the OSS environment consisting of an address space, a single thread of control that
executes within that address space, and the system resources required by that thread
of control. See also process type.
process identification number (PIN). An unsigned integer that identifies a process within a
processor module in a Tandem NonStop system.
process management. The act of configuring, creating, and initializing processes; the
monitoring and stopping of processes; and the recovery of failed processes. The
PATHMON process provides process management functions for OLTP applications on
Tandem NonStop systems.
process pair. A fault-tolerant arrangement of processes in the Guardian environment,
whereby two processes in separate processors share the same name and execute
identical code. One process functions as the primary process and the other functions
as the backup process. The two processes are kept in sync through checkpoint
messages sent from the primary to the backup process. If the primary process fails, the
backup process is notified that it is now the primary, and it resumes the application
work from the last valid checkpoint message.
process type. An attribute of a server class indicating whether the server processes in that
server class are Guardian processes or OSS processes. See also process.
program file. An executable object file. See also object file.
PROGRAM object. A template for creating and starting temporary TERM objects. See also
temporary TERM object.
pseudocode file. A file containing compiled code that is interpreted by software instead of
being executed by the hardware. The SCREEN COBOL compiler produces
pseudocode to be interpreted by the TCP. See also object file.
pseudo Pathsend procedure. In the Extended General Device Support (GDSX) software,
one of the TSCODE-supported procedures that have Pathsend procedure
counterparts.
pTAL. A machine-independent systems programming language based on TAL. The pTAL
language excludes architecture-specific TAL constructs and includes new constructs
that replace the architecture-specific constructs. See also Transaction Application
Language (TAL).
