Kill server instance when 'Thread Pool Stuck Thread' is detected

[Javian Berts]

I would like to shutdown my server instance whenever a thread is detected to be stuck for a period of time so that my nodemanager could bring it up again. How do I come about doing that?

Thanks in advance.

Technically you could do that by looking up a thread related MBean and restarting the server when your program detects that there are stuck threads.

However the right approach would be to figure out why the threads are 'STUCK' in the first place

you can guide the server to restart the server when the number of stuck threads exceeds a particular limit.

check the admin console for the same!

I did this using the node manager, and it worked!

Hi guys,

Thanks for all your input. Really appreciate it.

Sudipto, are you using the workmanager to do so? I am following the steps listed on:

http://download.oracle.com/docs/cd/E15523_01/web.1111/e13701/self_tuned.htm


However, I am not sure where to place this segment:

<work-manager>
<name>stuckthread_workmanager</name>
<work-manager-shutdown-trigger>
<max-stuck-thread-time>30</max-stuck-thread-time>
<stuck-thread-count>2</stuck-thread-count>
</work-manager-shutdown-trigger>
</work-manager>

in the config.xml. Any idea where I should put it? Thanks again.
