java has not enouth space, how to increase it?

Question

I need to run a very big task in eclipse. So I changed the eclipse.ini to:

--launcher.defaultAction
openFile
-vmargs
-Xms64m
-Xmx1024m

but this is still not enough. When I increase the Xmx to 2048 and try to start eclipse I get the message:

Failed to create the Java VM

How to avoid this? My system has 8Gb of RAM. So 2gb for Java should be no problem. Why doesn't it start?

You need to configure the Run Task. The config you are doing is for Eclipse only. — nhahtdh, May 02 '13 at 10:29

I am assuming you are using windows. You can only apply maximum 2GB to a 32bit process. see http://msdn.microsoft.com/en-us/library/windows/desktop/aa366778(v=vs.85).aspx#memory_limits

I suggest to switch to a 64bit JVM.

But probably as already suggested, you should also configure your task within eclipse.

It is not possible to allocate higher memory for Heap. There is limitation for this. Please go through this oracle site. This gives you the idea in detail.
