TS/MP 2.5 System Management Manual

PATHMON process The central controlling process in the Pathway environment. The PATHMON process maintains
configuration-related data; grants links to server classes in response to requests from TCPs and
ACS subsystem processes; and performs all process control (starting, monitoring, restarting, and
stopping) of server processes and TCPs.
PATHMON-controlled
object
An object defined and managed by a PATHMON process, through PATHCOM or the Pathway
management programming interface. In the PATHCOM interface, such an object can be of type
PATHWAY, PATHMON, SERVER, TCP, TERM, PROGRAM, or TELL. See also object and Pathway
object.
pathname See OSS pathname.
Pathsend
procedures
The set of Guardian procedure calls that provide general access to Pathway server classes from
any process on a Tandem system.
Pathsend process A process, written as a Guardian program in C, C++, COBOL, Pascal, pTAL, or TAL, that makes
calls to Pathsend procedures to request services from a Pathway server. A Pathsend process can
be either a standard requestor, which initiates application requests, or a nested server, which is
configured as a server class but acts as a requestor by making requests to other servers. A Pathsend
process is also known as a Pathsend requestor.
Pathsend program A Guardian program, written in C, C++, COBOL, Pascal, pTAL, or TAL, that makes calls to
Pathsend procedures to request services from a Pathway server. A running Pathsend program is
called a Pathsend process. See also Pathsend process.
Pathsend requestor See Pathsend process.
PATHTCP2 The TCP object file, usually identified by the file name $SYSTEM.SYSTEM.PATHTCP2.
PATHTCPL The TCP user library object file.
Pathway
application
A set of programs that perform online transaction processing tasks in the Guardian environment,
using interfaces defined by Tandem. A Pathway application can include SCREEN COBOL
requestors, Pathsend requestors, and Pathway servers running on Tandem NonStop systems. It
can also include GDSX front-end processes and clients that use RSC or POET. See also NonStop
TUXEDO application and PTP application.
Pathway
application
development
environment
A set of tools supporting the development of applications for the Pathway transaction processing
environment. Depending on the customer’s needs and software configuration, this set of tools
could include the SCREEN COBOL compiler and the SCREEN COBOL Utility Program (SCUP),
the POET application development tools, the Pathmaker product, and various tools from Tandem
Alliance partners. See also Pathway transaction processing environment.
Pathway Domain
Management
Interface (PDMI)
A management interface with a set of commands for configuring, controlling, and monitoring
multiple PATHMON processes. Typically, it is used to work with multiple PATHMON processes
under a single Pathway domain.
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 Pathway subsystem and subsystem ID.
Pathway monitor
process
See PATHMON process.
Pathway object An object in the Pathway transaction processing environment. The set of Pathway objects is a
more inclusive set than the set of PATHMON-controlled objects: for example, a ACS subsystem
process is a Pathway object but not a PATHMON-controlled object. See also object,
PATHMON-controlled object, and Pathway transaction processing environment.
Pathway Open
Environment
Toolkit (POET)
A set of programs and utilities that helps programmers create and run client/transaction server
applications. In the POET environment, the client is a program running on a workstation, and the
server is a Pathway server running on a Tandem NonStop system. POET uses the services of the
Remote Server Call (RSC) product. The programming tools provided by POET include a simplified
programming interface, name mapping, and conversion mapping.
