Hi all,

Weird - I only got this response and nothing else from the list...

Anyways, I'm not using solr - Just Tomcat - and I don't have Tomcat as a 
I have a startup script for it. Should I just place JAVA_OPTS in the 
startup script?

I'm on linux/redhat btw -

So my script does this:

export JAVA_OPTS="-server -Xms512m -Xmx1024M -Xms64M -Dfile.encoding=UTF-8"


Does it make sense to define JAVA_OPTS here?
