Question

I want to profile tomcat server with a java profiler. My profiler runs from the script say run.sh which looks like below:

if [ -z "$JAVACMD" ] ; then
   if [ -n "$JAVA_HOME" ] ; then
      JAVACMD="$JAVA_HOME/bin/java"
   else
      JAVACMD="`which java`"
   fi
 fi

if [ ! -x "$JAVACMD" ] ; then
 echo "Error: JAVA_HOME is not defined correctly; cannot execute: $JAVACMD"
 exit 1
fi


java  -javaagent:lib/jborat-agent.jar \
 -Dch.usi.dag.jborat.exclusionList="conf/exclusion.lst" \
  -Dch.usi.dag.jborat.liblist="conf/lib.lst" \
   -Dch.usi.dag.jp2.outputFilePrefix="output" \
   -Dch.usi.dag.jborat.instrumentation="ch.usi.dag.jp2.instrument.AddInstrumentation" \
   -Dch.usi.dag.jp2.dumpers="ch.usi.dag.jp2.dump.xml.XmlDumper" \
     -Dch.usi.dag.jborat.codemergerList="conf/codemerger.lst" \
      -Xbootclasspath/p:./lib/Thread_JP2.jar:lib/jborat-runtime.jar:lib/jp2-runtime.jar/jp2.jar/jborat-agent.jar/jborat.jar $* 

Could somebody please guide me how can I include this profiler in tomcat ?

Is it possible to write something like this CATALINA_OPTS=”$CATALINA_OPTS -javaagent:run.sh” in catalina.sh ?

I would really appreciate any help regarding this.

Thanks.

I tried adding options of run.sh (profiler) to setenv.sh as below but does not work. It does not give any error but The server is not starting. I dont know why.

Here is my setenv.sh file:

 #!/bin/sh
export CATALINA_OPTS="java -javaagent:lib/jborat-agent.jar \
 -Dch.usi.dag.jborat.exclusionList="conf/exclusion.lst" \
  -Dch.usi.dag.jborat.liblist="conf/lib.lst" \
   -Dch.usi.dag.jp2.outputFilePrefix="output" \
   -Dch.usi.dag.jborat.instrumentation="ch.usi.dag.jp2.instrument.AddInstrumentation" \
   -Dch.usi.dag.jp2.dumpers="ch.usi.dag.jp2.dump.xml.XmlDumper" \
     -Dch.usi.dag.jborat.codemergerList="conf/codemerger.lst" \
      -Xbootclasspath/p:./lib/Thread_JP2.jar:lib/jborat-runtime.jar:lib/jp2-runtime.jar/jp2.jar/jborat-agent.jar/jborat.jar "

I already answered your exact same question yesterday. Briefly, you want this:

$ export CATALINA_OPTS="-javaagent:lib/jborat-agent.jar -Xss256m -Xms256m  \ -Dch.usi.dag.jborat.exclusionList="conf/exclusion.lst" \ -Dch.usi.dag.jp2.dumpers="ch.usi.dag.jp2.dump.xml.XmlDumper" \ -Xbootclasspath/p:./lib/Thread_JP2.jar:lib/jborat-runtime.jar:lib/jp2-runtime.ja‌​r"
$ $CATALINA_HOME/bin/startup.sh

I don’t understand why you need more than that: your script just adds a bunch of system properties to the JVM launcher: you can do that with $CATALINA_OPTS. If you want to set them somewhat permanently, put the export into bin/setenv.sh and it will automatically be run every time you run bin/startup.sh (and bin/shutdown.sh for that matter).
