process pair
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).
PTP application. A collection of software components that perform transaction processing
for CICS applications in the Guardian environment on Tandem NonStop systems. See
also Customer Information Control System (CICS) and Parallel Transaction Processing
(PTP) Services for the CICS API product.
PTP Services product. See Parallel Transaction Processing (PTP) Services for the CICS
API product.
PTP server. A server in the PTP transaction processing environment. See also Customer
Information Control System (CICS), PTP transaction processing environment, and
Parallel Transaction Processing (PTP) Services for the CICS API product.
PTP transaction processing environment. An environment that supports the CICS/ESA
3.3 command-level application program interface (API) and provides run-time services
for CICS applications in the Guardian environment. The PTP environment provides the
Tandem fundamentals for CICS applications. See also Customer Information Control
System (CICS), Parallel Transaction Processing (PTP) Services for the CICS API
product, and PTP application.
