large java heap size
The maximum java heap for most operating systems is '-Xmx 2048M' (2g) but most machines have physical support for 4GB,8GB,16GB of RAM.
What hardware/OS combination supports values greater than this?
I've read that you need solaris with the '-d64 -Xmx 4g' options but is that for 64-bit sparc or x86? Also, could you run solaris under VMWare Fusion on x86 64-bit and get the same large java heap size results?
For example, run solaris x86 under Fusion on Intel MacPro 64 Quad-Core with 8GB physical memory then 'java -d64 -Xms 3g -Xmx 5g', could it work?
