This topic explains the automated heap dump generation support, which is only available on IBM Software Development Kit and analyzes memory leak problems.
Instructions from support involve setting environment variables, restarting the application server, and using the wsadmin tool. To help you analyze memory leak problems when memory leak detection occurs, some automated heap dump generation support is available. This functionality is only available on IBM Software Development Kit.
Most memory leak analysis tools perform some forms of difference evaluation on two heap dumps. Upon detection of a suspicious memory situation, two heap dumps are automatically generated at appropriate times. The general idea is to take an initial heap dump as soon as problem detection occurs. Monitor the memory usage and take another heap dump when you determine that enough memory is leaked, so that you can compare the heap dumps to find the source of the leak.
