Configuring Limits for Pathway/iTS 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 application−such as one supporting 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.
Configuring Limits for Pathway/iTS Objects
The SET PATHWAY command requires you to define limits for TCP, TERM and
PROGRAM objects configured under the Pathway/iTS product. Limits are global
values that determine the maximum number of objects of each type you can define
when you are ready to configure individual objects. For example, suppose that you
want to indicate that your system will permit a maximum of 2 TCPs and 50 TERM
objects. To establish these limits, you enter these commands:
= SET PATHWAY MAXTCPS 2
= SET PATHWAY MAXTERMS 50
For more information about use of the SET PATHWAY command to configure these
Pathway/iTS limits, including syntax descriptions, see Section 8, Pathway Environment
Control Commands. For additional information on configuring, starting, and managing
your overall PATHMON and Pathway environments, see the TS/MP System
Management Manual.
Specifying Limits
You must use the SET PATHWAY command to define these required limits before
executing a START PATHWAY command:
•
MAXTCPS−specifies the maximum number of TCP descriptions that you can add
to the PATHMON configuration file.
•
MAXTERMS−specifies the maximum number of descriptions for dynamic
terminals, static terminals, or dynamic and static terminals that you add to the
PATHMON configuration file using the ADD TERM and RUN PROGRAM
commands.
In addition to the required limits, you can specify limits for other attributes. For other
attributes, if you do not specify a limit, a default is assigned. For example,
MAXPROGRAMS is the maximum number of PROGRAM descriptions that you can
add to the PATHMON configuration file.
Specifying limits always involves some guessing, with penalties if you estimate wrong.
