How to generate thread dumps

[Daniel Addo]

Can anyone show me how to generate threaddumps for EM every 2 seconds for up to 30 threaddumps?

 

 

Thanks,

Here is a site that explains how to take a thread dump from when you run the EM in a dos window and also on Linux.

Hi,

        So the simple thing here is to ps –ef | grep wily, when I get the pid for wily use this command

Kill -3 wily_PID ?

 

Please confirm.

 

 

Thanks,

This is what I used a while ago to do the same thing. You control-C it when you are done.

 

#!/bin/ksh

pid=`ps -ef | grep -i introscope | grep -v grep | awk '{print $2}'`

echo "java pid is $pid"

while true

do

  timestamp=`date +"%m/%d/%y %H:%M:%S"`

  echo "issuing thread dump at $timestamp"

  kill -3 $pid

  sleep 15

done

Hi Daniel:

Do you feel you have the necessary directions that you need to create an EM thread dump? Or there are some parts needing additional clarification?

 

Thanks

Hi Daniel:

    All of the various questions that you had have been answered and you should be able to create a thread dump at this time based on the responses given. So I am marking as answered. You are welcome to ask follow-up questions as needed

Hello Hallett,

                          I believe I have the information I need to proceed. One more question, does this impact resources on the server?

 

 

 

Thanks,

Hi Daniel,

 

Any extra thing you perform on the server will take up additional resources, however, taking the thread dumps will only be a slight bump up in resources taken up and will not break the bank so to speak.

 

Thanks,
