Instrumenting v10.1 Java Agent on Tomcat App Server v6.0.37

[Manish Parikh]

I have a customer with attached "startup.sh" script that calls "catalina.sh" Where should I put the JVM Args to instrument Introscope Agent v10.1 and what args. And what exact args should I put in?

What I was thinking was to put the following args in the "startup.sh" script towards the beginning...

-javaagent:/apps/CA/IntroscopeAgent10.1/wily/Agent.jar -Dcom.wily.introscope.agentProfile=/apps/CA/IntroscopeAgent10.1/Tomcat6/wily/core/config/IntroscopeAgent.profile

 

Do I need to set/define a variable called "JAVA_OPTS" or anything like that w/n the "startup.sh" script?.Or should I input the args in "catalina.sh"? If so, what exact args and where w/n the "catalina.sh"?

 

Thanks in advance for all the assistance.

Hi Manish,

As startup.sh already sets JAVA_OPTS and exports it for use in the called catalina.sh script you should be able to add the java agent arguments to that same JAVA_OPTS & they will be processed in catalina.sh.

So basically do the following?

 

JAVA_OPTS="-Xms128M -Xmx4096M -XX:MaxPermSize=512M"

JAVA_OPTS="-javaagent:/apps/CA/IntroscopeAgent10.1/wily/Agent.jar -Dcom.wily.introscope.agentProfile=/apps/CA/IntroscopeAgent10.1/Tomcat6/wily/core/config/IntroscopeAgent.profile"

Make sure to append and not replace your previous values.

[Manish Parikh]

Ok so I'll input it this way

 

JAVA_OPTS="-Xms128M -Xmx4096M -XX:MaxPermSize=512M;-javaagent:/apps/CA/IntroscopeAgent10.1/wily/Agent.jar -Dcom.wily.introscope.agentProfile=/apps/CA/IntroscopeAgent10.1/Tomcat6/wily/core/config/IntroscopeAgent.profile”

 

That should work.

[Haruhiko Davis]

Is this Windows then since you're using a semicolon?

[Manish Parikh]

No, this is a linux box. Guess semicolon is not the correct syntax. What should it be?

[Haruhiko Davis]

Use a colon

Hi Manish:

   With Hiko's suggestions were you able to get to this to work or are experiencing new issues? Please let us know

Hallett_German,

The App Server admin has not applied the instrumentation yet. Should have an answer today though.

Thanks

But in the case you've shown, you do not need a divider since '-javaagent' is the start of another property. Just put a space between the last property and '-javaagent'.

Hi Manish:

    Please let us know setting the JAVA_OPTS in startup.sh works as you expect. Or do you then encounter an issue?

Hi Manish:

I am marking as assumed answered since there has no resolution yet. And no follow-up is needed at this time. If the solution works, please mark Lynn's response on 10-24 as correct. 

[Manish Parikh]

The solution worked yesterday. Thanks Lynn_Williams and Hiko_Davis for your help.

 

JAVA_OPTS="-Xms128M -Xmx4096M -XX:MaxPermSize=512M -javaagent:/apps/CA/IntroscopeAgent10.1/wily/Agent.jar -Dcom.wily.introscope.agentProfile=/apps/CA/IntroscopeAgent10.1/Tomcat6/wily/core/config/IntroscopeAgent.profile”

Thanks Manish for letting us know about the good news!
