Can anybody tell me, how can I get the heap dump (.hprof) file to get in windows with JDK1.5 ? I have setup Mat in my eclipse and JDK1.5 is the environment, but trying to create heap dump file when my application is running?

Thanks

Hi,

Since update 15, the jdk 1.5 also accepts the option to dump the heap when the user presses ctrl + break on windows.

The option you need to set in the VM parameters is:
-XX:+HeapDumpOnCtrlBreak

We should add this info to our wiki description how to get dumps.

Regards,
Krum
