Displaying Configuration Information
•
You can add another TCP object that might or might not be dedicated exclusively
to the RUN PROGRAM command.
You must keep in mind, however, that when you make a change to your configuration,
the change can affect other performance factors.
If you add 25 TERM objects to TCP-PROBLEM, for example:
•
Users might encounter response time problems unless you increase the size of
buffer space that TCP-PROBLEM allots for I/O operations to terminals. (That is,
TCP TERMPOOL might be insufficient for the added terminals.)
•
There might be insufficient server links available in TCP-PROBLEM.
•
There might be an insufficient total number of links.
•
There might be an increase in response time due to contention for the data or code
areas.
•
The workload might no longer be distributed evenly among CPUs in the system.
You can use the STATS command to view information about response time, memory
management and allocation, link management, and so on.
For another example, if you add a TCP:
•
All of the issues described for adding TERM objects could apply for adding a TCP.
•
The TCP requires new swap file space on disk.
•
There will be increased demand for memory in the CPU.
•
There will be increased demand for other system resources, such as increased
need for memory segments.
Whenever you add PATHMON-controlled objects to your configuration, you must
ensure that you are still within the limits defined for your system (use the INFO
command).
To ensure proper maintenance of your PATHMON environment, you must monitor its
performance on a regular basis, make changes when required, and always monitor the
effects of any changes that you make.
Displaying Configuration Information
The INFO command displays configuration information. Use the INFO command to
display configuration information about TCP, TERM, and PROGRAM objects. For
instructions on using the INFO command to display information for objects and
processes running under TS/MP−for example, the PATHMON process and SERVER
objects−see the TS/MP System Management Manual.
