javaone 2012 presentation on Diagnosing Your Application on the JVM : Question on attach on Windows

[Bacchu, Anjan]

Hi Staffan,

      I just now saw the presentation slides at http://www.slideshare.net/stalar/diagnosing-your-application-on-the-jvm.

On Slide 16 of the presentation, you show the details of the "HotSpot Dynamic Attach Mechanism" for Windows.


1)  You talk about Remote process injecting code into the JVM using combination of VirtualAllocEx and

2)  WriteProcessMemory. Further it goes ahead and creates a Remote thread in the JVM to call above code.


Do you have some sample code which does this, to say, dump the heap ?

I used to develop windows application long ago and just from the slide #16 and http://openjdk.java.net/groups/hotspot/docs/Serviceability.html#battach, I'm unable to proceed further.

All help will be useful.

Thank you very much,

BR,
~A
