Steps to Optimum Link Configuration
For example, suppose transaction-1 requires 90 active links to the server class,
transaction-2 requires 5 active links, transaction-3 requires 10 active links, and
transaction-4 requires 15 active links.
90 + 5 + 10 + 15 = 120 total active links required
The value you specify for MAXSERVERS should be 120.
Step 7 Calculate Link Manager Demand for Links
Use the results from Steps 2 and 6 to determine how many links are required to
support your link manager environment. This value is used in Step 8 to calculate the
value for MAXLINKS.
LINKMON Processes
For LINKMON processes, use this formula:
where the constant is a safety factor, MAXSERVERS is the result of Step 6, and no.
of CPUs is the total number of CPUs that have LINKMON processes configured. The
result, no. of links required by LINKMON processes, is the total potential
LINKMON demand for links to the server class.
This example uses the value 1 as the constant:
20 x 6 CPUs = 120 links required by the LINKMON processes
Assuming the norm of one LINKMON process per processor, this configuration
supports six LINKMON processes sharing 120 links.
TCPS
For TCPs, use this formula:
Note. Because it is recommended that you run your application with static servers only, you
should specify the same value for NUMSTATIC that you specify for MAXSERVERS.
no. of links required = constant x MAXSERVERS
x no. of CPUs
no. of CPUs
1 x MAXSERVERS=120 = 20
6 CPUs
no. of links required = constant x
MAXSERVERS x no. of TCPs
no. of TCPs
