title: Setting heap size in Tomcat
body: <p>I am working on the apache tomcat server in unix enviroment. I want to increase the heap size of my application and so I am setting it in the catalina.sh file . This is how I am doing it ...</p>
  
  <p>export CATALINA_OPTS="-Xms1024m -Xmx1024m"
    echo $CATALINA_OPTS</p>
  
  <p>When i call the startup.sh it calls catalina.sh and sets the variable CATALINA_OPTS to 1024 as indicated by the echo statement in the script. But if I do echo $CATALINA_OPTS at the command prompt it gives blank. Is this expected behavior. How can I be sure that the correct heap value has indeed been picked up ?</p>
