[SOLVED] Increase tomcat memory on Debian 7

Issue

I have installed Tomcat7 on Debian Wheezy, the max memory is only 128Mo. So I have tried to change the file /etc/init.d/tomcat7 by changing :

if [ -z "$JAVA_OPTS" ]; then JAVA_OPTS="-Djava.awt.headless=true -Xmx128M" fi

by

if [ -z "$JAVA_OPTS" ]; then JAVA_OPTS="-Djava.awt.headless=true -Xmx1024m -XX:MaxPermSize=256m" fi

After a restart of tomcat (command : "service tomcat7 restart"), the memory hasn't changed at all. Is there another way to change it?

Thank you.

Solution

You may edit it the file /etc/default/tomcat7; then find the line JAVA_OPTS and change it, example below:

JAVA_OPTS="-Djava.awt.headless=true -Xmx1024m -XX:+UseConcMarkSweepGC

Then restart tomcat 7:

service tomcat7 restart
