Subject Re: 2GB limit on 32 bits
Date Fri, 09 Nov 2007 15:26:57 GMT
Some OSs split that 4GB into a 2GB data space and a 2GB instruction
space. To get a 64bit address space, the CPU, OS, and JVM all need
to support 64 bits. There have been 64 bit Xeon chips since 2004,
the Linux 2.6 kernel supports 64 bit, and recent JVMs do, too.
If your Xeon supports 64 bits, you should be able to get the rest
of it to do 64 bits.

I'm not an expert on configuring that stuff, though.
