How to analyse the heap dump using jmap in java

Question

I am creating heap dump using below command:

jmap -dump:file=DumpFile.txt 

I have opened the generated file - DumpF

Answer 1

You should use jmap -heap:format=b without any paths. So it creates a *.bin file which you can open with jvisualvm.exe (same path as jmap). It's a great tool to open such dump files.
