Objects and Processes Provided by Pathway/iTS
Pathsend requesters. (Under Pathway/iTS, the TCP is the link manager for
SCREEN COBOL requesters.)
Objects and Processes Provided by Pathway/iTS
These elements of a Pathway environment are provided by the Pathway/iTS product.
Information about configuring and managing these items is covered in the Pathway/iTS
System Management Manual .
•
TCP objects—terminal control processes that execute screen (SCREEN COBOL)
programs and coordinate communication between screen programs, input-output
devices or processes, server processes, and the PATHMON process.
•
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 an OLTP application.
•
PROGRAM objects—templates for creating and starting temporary TERM objects.
Pathway Environment Configurations
Depending on your configuration, a Pathway environment may also include other
software, such as TMF and the run-time portion of the Remote Server Call (RSC)
product, and the Pathway Open Environment Toolkit (POET) run-time environment.
Figure 1-1 on page 1-3 illustrates a Pathway environment that includes the NonStop
TS/MP product and the Pathway/iTS product. In this example, a remote system uses
Pathsend requesters to access the server processes, with link management provided
by LINKMON. A set of Pathway/iTS application terminals makes requests through the
TCP. Additional elements of the application include the PATHMON process that
manages the TCP, TERM, and SERVER objects, a command terminal running
PATHCOM, and a management programming application.
Figure 1-2 on page 1-4 shows an example of a NonStop TS/MP application configured
in two operating environments. A remote system sends Pathsend requests to the
LINKMON process, which manages communications with the server classes. One
server class is configured in the OSS operating environment. The other server class
resides in the Guardian operating environment. The PATHMON process, the
PATHCOM interactive interface, and a management programming application are all
Guardian processes.
