Re: [Condor-users] Java Universe Red Hat 8 configuration problem

[Mark Silberstein <marks@xxxxxxxxxxxxxxxxxxxxxxx>]

If you use Sun java, I'd recommend putting
JAVA_MAXHEAP_ARGUMENT   = -Xmx$(Memory)
To make sure that your java universe job takes advantage of ALL the
memory on the computer. It makes a huge difference in performance

I am not running an ancient computer with a small amount of diskspace or Memory so the Requirements error I am getting is confusing me. Does anybody have any suggestions on what I could try or change to get my Java universe properly running or can somebody point me in the direction of a resource that can get me on my way to solving this problem. Your help will be apprectiated. Thank you.
