Objects and Processes Provided by Pathway/iTS
•
PATHMON—the process that manages TCP, TERM, PROGRAM, and SERVER
objects. The PATHMON process and the objects controlled by it make up the
PATHMON environment. Each PATHMON environment includes only one
PATHMON process.
•
PATHCOM—the interactive interface to the PATHMON process. As an alternative
to using PATHCOM, you can write a management application program, using the
Subsystem Programmatic Interface (SPI).
•
SERVER objects—definitions of server classes (multiple copies of server
programs). An executing server program is called a server process. You use the
PATHMON process to configure and manage Guardian server programs, which
reside in the Guardian operating environment, and HP NonStop Open System
Services (OSS) server programs, which reside in the OSS operating environment.
•
LINKMON—the process that manages communications between Pathsend
processes and server classes. (Pathsend processes are user applications that use
Pathsend procedure calls, rather than the SCREEN COBOL language, to send
requests to server classes. )
Objects and Processes Provided by Pathway/iTS
The following elements of a Pathway environment are provided by the Pathway/iTS
product.
•
TCP objects—terminal control processes that perform these functions:
•
execute screen (SCREEN COBOL) programs in your application
•
coordinate communication between screen programs, input-output devices or
processes, server processes, and the PATHMON process
•
coordinate communication between router processes and web clients
•
coordinate communication between router processes and intelligent devices
that use the sockets protocol
•
TERM objects—definitions of tasks that use screen programs to control input-
output devices such as terminals and workstations, or input-output processes that
enable users to communicate with a Pathway application.
•
PROGRAM objects—templates for creating and starting temporary TERM objects.
•
Router processes—processes that provide link management and load balancing
for web clients and for intelligent devices that use the sockets protocol.
Information about defining and managing these items is given in this manual.
However, the router processes are not managed objects within the Pathway
environment. If you are using PATHCOM or the management programming interface
to configure and manage your Pathway environment, you must start the router
processes in the Guardian environment (for example, through the HP Tandem
Advanced Command Language (TACL)) and only limited management capabilities are
