Increasing Heap size issue

mehmood_khan

Hi,

I am using Rapidminer 4.3.I want to run Kmeans but the dataset is too large. I increased VM heap size upto 1.6GB but heap gets overflowed. I want to increase it up to 3GB, as I do have 8GB physical memory in the system, using command:

lib> java -Xms64m -Xmx3072m -jar rapidminer.jar

but prompt with an error:
C:\Program Files\Rapid-I\RapidMiner-4.3\lib>java -Xms64m -Xmx3072m -jar rapidminer.jar
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

Can any body please help me here?
