Enable the lightweight memory leak detection

Use this task to enable the lightweight memory leak detection using the Runtime Performance 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.
