Tools For Analysing Java Heap Dumps
The heap dumps produced by the IBM® SDK, Java™ Technology Edition need to be post processed in order to generate meaningful information about the objects on the Java heap.
The IBM SDK, Java Technology Edition provides an option to generate a heap dump with a minimal performance impact trigger.
For information about heap dumps, including default and optional settings for them, see the IBM Knowledge Center:
There are multiple tools available that post process the heap dumps and allow analysis in terms of data collections and object graphs. The recommended tool is IBM Monitoring and Diagnostic Tools for Java - Memory Analyzer.
Note that heap dumps are platform agnostic and can be analysed on any platform regardless of where they were created.
IBM Monitoring and Diagnostic Tools for Java - Memory Analyzer is available as part of the IBM Support Assistant workbench. More details can be found here:
