The enhancements specific to SAP NetWeaver are add-ons to the Eclipse Memory Analyzer (available at http://www.eclipse.org/mat). The Eclipse Memory Analyzer is a fast and feature-rich Java heap analyzer that helps you find memory leaks and reduce memory consumption.

The Memory Analyzer was developed to analyze productive heap dumps with hundreds of millions of objects. Once the heap dump is parsed, you can re-open it instantly, immediately get the retained size of single objects and quickly approximate the retained size of a set of objects. The reference chain to the Garbage Collection Roots then details why the object is not garbage collected.

Using these features, a report automatically extracts leak suspects. It includes details about the objects accumulated, the path to the GC Roots, plus general information like system properties.

The SAP NetWeaver enhancements to the Memory Analyzer contain several queries and reports which makes it easier to analyze heap dumps derived from a SAP Netweaver Application Server. You can get an overview of the Application Server, see the deployed SCAs and check the sessions, caches, and more.
