Steps to Optimum Link Configuration

The balance of this subsection covers the steps you can follow to arrive at initial values

for critical configuration variables that directly affect application performance. These

values offer a starting point for your configuration parameters. After starting your

PATHMON environment, you might want to fine tune some variables based on

application performance. Guidelines are provided for performing these steps.

1. Identify the number of Pathsend requesters or terminals your application must

support.

2. Determine how many link managers (LINKMON processes or TCPs) your

configuration requires.

3. Calculate the working average transaction volume for each transaction type in the

application.

4. Measure server class response time.

5. Calculate the number of active links to the server class required by each

transaction type.

6. Add up the sum of all the active links for all the transaction types that use the

server class to give the total active links. This is the total active links the server

class must be able to support at any given moment. Use the result as the value

you specify for the server class MAXSERVERS attribute and NUMSTATIC.

7. Calculate the potential link manager demand for links to the server class.

8. Calculate the value you must specify for the server class MAXLINKS attribute.

Note. Steps 1 and 3 apply to your entire configuration. Steps 4-9 apply to server classes only,

and must be performed for each server class you configure. Step 10 applies to TCP

configurations in Pathway/iTS environments.
