Pathway subsystem
Pathway subsystem. The PATHMON environment components to which SPI commands are
sent under the Pathway subsystem ID and which generate EMS event messages with the
Pathway subsystem ID. All SPI commands for the Pathway subsystem are sent to the
PATHMON process, but the processsing for the command might involve other
processes, such as a TCP. Likewise, all EMS messages from the Pathway subsystem are
generated by the PATHMON process, but the information might originate from another
process. See also subsystem ID.
Pathway system. A term formerly used for the set of objects managed by a particular
PATHMON process; now called PATHMON environment. See PATHMON environment.
Pathway transaction processing environment. A run-time environment consisting of
Tandem’s transaction-processing products for the Guardian operating environment. This
term is often shortened to “Pathway environment.” Depending on the customer’s needs
and software configuration, the Pathway environment could include NonStop TS/MP,
the run-time portions of Pathway/TS (the TCP and the SCREEN COBOL run-time
environment), NonStop TM/MP, GDSX processes, the run-time portion of the RSC
product, the POET run-time environment, and the TRANSFER delivery system (when
used as a workflow aid in transaction processing). See also NonStop TUXEDO
transaction processing environment.
Pathway translation server for the NonStop TUXEDO system. A server process, provided
by Tandem as part of the NonStop TUXEDO product, that allows a Pathway (SCREEN
COBOL or Pathsend) requester to use the services of a NonStop TUXEDO server. The
translation server thus acts as a gateway process between the Pathway environment and
the NonStop TUXEDO environment. Requesters that use this translation server must
include special information in the header of each request message to identify the target
NonStop TUXEDO application and service.
Pathway/TS. A Tandem product that provides tools for developing and interpreting screen
programs to support OLTP applications in the Guardian environment on Tandem
NonStop systems. Pathway/TS screen programs communicate with terminals and
intelligent devices. Pathway/TS includes the TCP, the SCREEN COBOL compiler and
run-time environment, and the SCREEN COBOL Utility Program (SCUP). It requires
the services of the NonStop TS/MP product. See also NonStop Transaction Services/MP
(NonStop TS/MP).
PIN. See process identification number (PIN).
POBJ. The default prefix, or file-name root, used by the SCREEN COBOL compiler in
naming its output files. If no prefix is specified in the RUN command to run the
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).
Portable Transaction Application Language (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).
