Lotus Notes

In my last post ( http://planetlotus.org/735190 ), I've mentioned adding JavaDebugString=-XX:MaxPermSize=256M in my workstation's notes.ini increased the heap size.But,it doesn't seems true when I tested with following piece of code ,

public void NotesMain() {

try {
Session session = getSession();
AgentContext agentContext = session.getAgentContext();

//Get the jvm heap size.
long heapSize = Runtime.getRuntime().totalMemory();
//Print the jvm heap size.
System.out.println("Heap Size = " + heapSize);


} catch(Exception e) {
e.printStackTrace();
}
}


It says 16777216 in both the cases. Does this setting only works on server's ini file or something wrong with my settings ? So, here are still my unanswered questions,

* How do I increase heap size of Java agents on client or server machine ?

* I assume increasing heap size may affect server performance, So is it possible to increase for just one agent or database ?

I've tried changing HTTPJVMMaxHeapSize but no effect.
