TS/MP 2.5 System Management Manual

Pathway server A server process or program in the Pathway transaction processing environment. See also NonStop
TUXEDO server and PTP server.
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) requestor 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. Requestors 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).
PDMCOM A new command-line interface used to start PDMI, configure, and manage multiple Pathway
environments at the same time. It is a superset of PATHCOM.
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 d)
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 A unique execution of a program in the Guardian environment.1.
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 broker (PB)
process
A process that executes in each processor within a system to manage the resources and link
reservations for the processor.
NOTE: The PB process is part of the ACS subsystem.
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.
