Start the lightweight memory leak detection

 

Use this task to start the lightweight memory leak detection using the Performance and Diagnostic Advisor. If you have a memory leak and want to confirm the leak, or you want to automatically generate heap dumps on Java virtual machines (JVM) in WebSphere Application Server, consider changing your minimum and maximum heap sizes to be equal. This change provides the memory leak detection more time for reliable diagnosis.

 

Overview

To start the lightweight memory leak detection using the Performance and Diagnostic Advisor, perform the following steps in the administrative console:

 

Procedure

  1. Click Servers > Application servers in the administrative console navigation tree.

  2. Click server_name > Performance and Diagnostic Advisor Configuration.

  3. Click the Runtime tab.

  4. Enable the Performance and Diagnostic Advisor Framework.

  5. Click OK.

  6. From the Runtime or Configuration tab of Performance and Diagnostic Advisor Framework, click Performance and Diagnostic Advice configuration.

  7. Start the memory leak detection advice and stop any other unwanted advice.

 

Results

The memory leak detection advice is started.

Important: To achieve the best results for performance tuning, start the Performance and Diagnostic Advisor when a stable production level load is running.

 

What to do next

You can monitor any notifications of memory leaks by checking the SystemOut.log file or Runtime Messages. For more information, see the Viewing the Performance and Diagnostic Advisor recommendations topic.
