Java heap size

Hello,

I am trying to increase the heap size of JVM. I am using Eclipse as an IDE.

I do so by using eclipse -vmargs -Xmx2048m..

And when I try to see whether JVM has increased the size by
Runtime rt = Runtime.getRuntime();
System.out.println(rt.maxMemory());

But I find that the memory maximum which could be allocated is just 980mb.

Can anyone help me with this ?

Thanks,
Jahangir

how much available memory do you have on the machine you are trying to run this on? Why does eclipse need 2G of ram?

Hi myself also faced this and got resolved by following approach..


Try this

Just navigate in u r eclipse

Windows --> prefeence-->java-->installed JRE-->click on the java version installed and click edit button right and give the value -Xmx768m in theDefault VM arguments and click ok.

Thast it..

Close the eclipse and open it again..
