IBM Heap Analyser -
I started getting "Java.lang.OutofMemoryError: Java heap space" when trying to read a heapdump file using the heap analyser. used the below on a windows 2008r2 server where I had 64bit java installed. specified the initial and max heapsize and it started working.
D:\Program Files\Java\jdk1.7.0_25\bin>java -Xms2g -Xmx6g -jar d:\temp\ha450.jar
