Start here for a summary of key performance tuning parameters
for your Intelligent Management configuration.
About this task
You can complete any of these steps to improve the performance
of your
Intelligent Management configuration.
Procedure
- Assign all URL patterns from an application to transaction
classes. Any URL that does not map to a transaction class
is classified as best effort, also called discretionary.
Transaction classes are part of service policies. To change transaction
classes from the administrative console, select .
- Check service policy goals against the performance of the
service class and adjust the goals if necessary. For
example, your service policy has an average response goal of 200 milliseconds
and the measured average service time is 300 milliseconds. Consider
adjusting your goal to 500 milliseconds.
- To change the application placement controller speed for
loading changes, adjust the following properties:
- Configure the minimum time between placement changes in the administrative
console. Select .
Set the minimum time between placement changes to a suitable value.
- Configure the application placement controller cycle from the
administrative console. Select . Add a custom
property with the name minControlCycleLength and
a suitable value in minutes.
- Adjust the control cycle length. The control
cycle length minimum property determines how quickly the autonomic
request flow manager (ARFM) reacts to load changes. You can change
the ARFM control cycle length. From the administrative console select .
Set the control cycle length minimum property to a suitable value.
- Adjust ARFM to limit the maximum use of the nodes.
- In the administrative console, select .
- Set the Maximum CPU Utilization property. Higher values
allow better resource use, lower values ensure more robust operation.
