Obtaining advice from the advisors
Advisors provide a variety of recommendations that help improve
the performance of your application server.
Before you begin
The advisors provide helpful performance as well
as diagnostic advice about the state of the application server.
About this task
Tuning WebSphere Application Server is a critical part of getting
the best performance from your Web site. However, tuning WebSphere Application
Server involves analyzing performance data and determining the optimal server
configuration. This determination requires considerable knowledge about the
various components in the application server and their performance characteristics.
The performance advisors encapsulate this knowledge, analyze the performance
data, and provide configuration recommendations to improve the application
server performance. Therefore, the performance advisors provide a starting
point to the application server tuning process and help you without requiring
that you become an expert.
The Runtime Performance Advisor
is extended to also provide diagnostic advice and is now called the Performance
and Diagnostic Advisor. Diagnostic advice provides useful information regarding
the state of the application server. Diagnostic advice is especially useful
when an application is not functioning as expected, or simply as a means of
monitoring the health of application server.
Procedure
- Decide which performance advisor is right for the purpose, Performance and Diagnostic Advisor or Tivoli Performance
Viewer advisor.
- Use the chosen advisor to periodically check for inefficient settings,
and to view recommendations.
- Analyze Performance Monitoring Infrastructure data with performance
advisors.
What to do next
Additionally, you can use the heap monitor feature
to monitor the Java Virtual Machine (JVM) heap size of a WebSphere Application
Server profile in comparison to pool size. The feature is available for new
WebSphere Application Server profiles or profiles that are created after you
update to the WebSphere Application Server. For existing WebSphere Application
Server profiles, there is a script available to add the feature. See
The heapMonitor script for
more information.
