Subject Re: How to set Java Memory heap size on Linux?
Date Mon, 09 Mar 2009 18:07:54 GMT
What is the syntax of the "setenv.sh script"?  Is it just line by line
setting environmental variables?
JAVA_OPTS=-Xms256m -Xmx768m
CATALINA_OPTS=

I am correct in assuming this is all I would need to populate the file with?
