title: Tomcat 6 Heap Size - Is this correct?
body: <p>I am running multiple tomcats on a Red Hat box and I would like to configure separate heap size for each of them (some instances use more memory).</p>
  
  <p>Can I set the heap size min/max bt entering the following into the catalina.sh file:</p>
  
  <p>CATALINA_OPTS="-Xms64m -Xmx256m"</p>
  
  <p>Do I need add 'export'? i.e. export CATALINA_OPTS="-Xms64m -Xmx256m"  </p>
