not enough heap space to run fisheye

[thu phan]

i'm trying to install JIRA suite on my local PC for a test run. I've been following the "here be dragon" instranctions to Dragons Stage 4 - Install FishEye and Crucible My machine is a Core Duo 3GHz with 4GB ram. when i run run.bat, i got error that JVM can't get neough heap memory... i just restarted my mchine and i don't think many things is running on it. JIRA not runing. Only MySql is running. Where do i check to reduce the amount of memmory fisheye JVM is trying to get?

thanks--
