TOMCAT 7, Can't change the heap size

I Have set the heap size of tomcat 7 by adding boot script:

export CATALINA_OPTS="-Xms1024m -Xmx248m"

I change /etc/init.d/tomcat7 :

if [ -z "$JAVA_OPTS" ]; then
        JAVA_OPTS="-Djava.awt.headless=true -Xmx2048M -Xms1024M"
fi

I Reboot the computer and restart the Tomcat:

service tomcat7 restart

And verify the $CATALINA_OPTS Works:

> echo $CATALINA_OPTS
-Xms1024m -Xmx2048m

But when I go to the tomcat manager, I note that the heap has not changed.

Free memory: 38.02 MB Total memory: 123.75 MB Max memory: 123.75 MB

Please, i need help about this.

Check the setenv.sh in tomcat/bin, according to manual this should be the right place to put those params.

Another option, it depend on your OS tomcat package, may be that config param are overrided in /etc/conf.d/tomcat/ or /etc/tomcat. Just check your init script and your catalina.sh to find where your settings are overrided.

Btw if you run a ps -ef | grep tomcat you should see the full command line with arguments: this may give you an idea of how init script build the command, and so you can investigate where params are set.

Have you tried creating a setenv.sh script in the $CATALINA_HOME/bin directory with your options in it?

I find that setting JAVA_OPTS="-Xmx2048m -Xms1024m" in there works pretty well.
