TS/MP 2.5 System Management Manual

Figure 17 PATHMON Environment With Multiple Applications
In some configurations, a single application spans multiple PATHMON environments that might
be distributed over a network. In cases where more than one PATHMON environment is involved,
each environment is monitored by the PATHMON process. For more information, see “Distributing
a Pathway or PATHMON Environment” (page 20).
Because NonStop systems support both Guardian and OSS operating environments, configurations
on these systems can include applications running in both operating environments. For an example
of a NonStop TS/MP application configured in two operating environments, see Figure 2 (page 20).
As a system manager for a PATHMON environment, you can configure and manage OSS server
objects.
How you configure a PATHMON environment depends on various management objectives: the
size of your application or applications, the number of users, response-time requirements, whether
the application is distributed over a network, and so on.
For example, a very large NonStop TS/MP application that includes Pathway/iTS objects−for
example, 100 terminal control processes, 1000 server classes, 40,000 links and 2000
terminals−might be configured in a single PATHMON environment with several TCPs to handle
the large number of TERM objects required for the application. If you are running such a system
on a single node, you might, for performance reasons, choose to create a separate PATHMON
environment to manage the server classes and their associated links. By distributing the application
among multiple processes, you improve response time).
