• Make sure that you adjust JAVA_OPTS so that both JVMs have enough memory. In our case this will be:

  No Format
  setenv JAVA_OPTS "-serverd64 -Xmx1500m -Xms1500m -Xmx1500m -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSParallelRemarkEnabled -XX:+UseAdaptiveSizePolicy -XX:PermSizeNewSize=16m256m -XX:MaxPermSize=128m=200m -XX:PermSize=64m -verboseXX:gcMaxTenuringThreshold=3 -XX:+PrintGCDetailsCMSInitiatingOccupancyFraction=75 -XX:+PrintGCTimeStampsMinHeapFreeRatio=18"

• When starting either tomcat instance, we have to make sure that we use specific CATALINA_HOME settings for each instance.
  • Starting tomcat1 Note that we set JAVA_HOME to Java v5 to run it in 64bit

    No Format
    cd JAVA_HOME=/ucd/pkg/tomcat1/bin setenvopt/java5 export JAVA_HOME CATALINA_HOME =/ucd/pkg/tomcat1 ; ./shutdown.sh ; ./ startup.sh ; tail -f ../logs/catalina.out

    Starting tomcat2

    No Format
    cd /ucd/pkg/tomcat2/bin setenvapache-tomcat-5.5.12-tc1 export CATALINA_HOME /ucd/pkg/apache-tomcat-5.5.12-tc1/bin/startup.sh CATALINA_HOME=/ucd/pkg/apache-tomcat-5.5.12-tc2 export CATALINA_HOME /ucd/pkg/tomcat2 ; ./shutdown.sh ; ./ apache-tomcat-5.5.12-tc2/bin/startup.sh ; tail -f ../logs/catalina.out

• Adjust "iptables" to allow traffic for both port 8180 as well as 8280

• Make sure that you adjust /etc/rc.d/rc.local to not just start one tomcat
