I read about jmap command , but i am not getting where and how to execute / write it (in eclipse or cmd). It might be a very basic question but still suggestions are requested.Can i download jmap.exe and jhat.exe from any where? Thank You

Start the administrative console. In the navigation pane, click Troubleshooting > Java dumps and cores. Select the server_name for which you want to generate the heap dump. Click Heap dump to generate the heap dump for your specified server.
The JDK comes with several tools to capture heap dumps in different ways. All these tools are located under the bin folder inside the JDK home directory.
Open Eclipse MAT To open the heapdump, go to File > Open Heap Dump (Not Acquire Heap Dump) and browse to your heapdump location.
The heap dump is written in heap. bin file in the current working directory.
Here is the command:
<JDK_HOME>/jmap -F -dump:live,format=b,file=<file_name.hprof> <process_id>
You can mention the file location here in this command.
