Pathsend requester
Pathway server. A Pathsend process can be either a standard requester, which
initiates application requests, or a nested server, which is configured as a server class
but acts as a requester by making requests to other servers. A Pathsend process is
also known as a Pathsend requester.
Pathsend requester. See Pathsend process.
Pathway application. A set of programs that perform online transaction-processing tasks in
the Guardian environment, using interfaces defined by HP. A Pathway application can
include COBOL requesters, Pathsend requesters, and Pathway servers running on HP
NonStop systems. It can also include front-end processes (which are a type of
Pathsend process) and clients that use RSC/MP. See also NonStop Tuxedo
application.
Pathway environment. See Pathway transaction-processing environment.
Pathway management-programming interface. A set of programmatic commands that
allow users to write management application programs that communicate directly with
the PATHMON process for configuration and management. This interface is based on
the Subsystem Programmatic Interface (SPI) within the Distributed Systems
Management (DSM) software. Programmatic commands communicating with the
PATHMON process use the Pathway subsystem ID. See also subsystem identifier.
Pathway TCP. See terminal control process (TCP).
Pathway transaction-processing environment. A run-time environment consisting of
HP’s transaction-processing products for the Guardian operating environment. This
environment could include NonStop TS/MP, the TCP and the COBOL run-time
environment, TMF, the run-time portion of the RSC/MP product, and the Transfer
delivery system. See also NonStop Tuxedo transaction-processing environment.
Pathway/iTS. An HP product that provides tools for developing and interpreting screen
programs to support OLTP applications in the Guardian environment on servers.
Pathway/iTS screen programs communicate with terminals and intelligent devices.
Pathway/iTS includes the TCP, the COBOL compiler and run-time environment, and
the COBOL Utility Program (SCUP). It requires the services of the NonStop TS/MP
product. See also NonStop Transaction Services/MP (NonStop TS/MP) and Pathway
transaction-processing environment.
performance management. Activities that manage the performance of the production
system and network environment to ensure that the systems meet the business needs
defined by operations service-level agreements.
persistent process. A process that is restarted or runs from a backup if the process stops.
See also immediate persistence, initialized persistence, and process pair.
phantom device. A device that is configured but that is not physically present. You can
make a phantom device operational without having to bring your NonStop system
