To give java more memory than 4g just use the -Xms/-Xmx options: java -Xmx6g for example. For tomcat you have to set memory in the catalina.bat as JAVA_OPTS variable: JAVA_OPTS="-mx6g -ms6g" for 6gb. regards Leon On 9/8/06, joon yoo wrote: > Hello, > > I'm a sysadmin, not a programmer so therefore my questions are limited > to server hardware and OS configuration. > > We're having memory management problems with java and our tomcat > webapp on a win2000 sp4 server: > > HP proliant DL360 G3 > Xeon 2.8 (HT on) > 2GB RAM > > I'm unable to expand java mem pool beyond 1024MB on this server. > > Would it make sense to upgrade to win2003 64bit and upgrade the RAM to > 8GB's.
