Dears,

Our IVR application uses Avaya OD 7.1, Java 7, IBMWAS server and AIC. We are facing IVR down issue when the call reaches more than 90 calls. The thread count mentioned in IBMWAS is 100 and AIC is set as 0. As per avaya recommendation, it needs to be set to 30.
Could you please advise, how we can simulate the issue in development environment since more than 90 calls can be tested in production only?

Thanks & Regards,

Basically, you need to understand that each live call takes one thread for executing the servlets and a specified set of threads in the thread pool for processing IC command in the IC connector. The thread pool sized can be verified in the IC connector log. For tracking performance you would have to use whatever IBM provides for Websphere. Last time I checked, the IBM console provides a set of those tools. Simulation does not work for performance tuning. You really need to run on a real system with IC connection.

For testing purpose, I set ThreadPoolSize in IC VRUSM/HTTPVOX page of runtimeConfig url. I started set with 0 and then 1 and then 2.
But for all settings, I received 0 active Thread as per below log. Attached the screenshot of runtimeconfig configurations.
How can we confirm if it is using the same thread configuration? Or Do we need to set in another place?

This log means there is thread that is available since there are no active thread (active thread means thread working on any request). It's just informative. If you set the thread pool size to 0, the default is 3. The log will tell you.

So, Will increasing Thread size from 0 to 30 be good enough to resolve our issues?
As stated before, the issue is after 90 calls the calls are not getting played and we have 90 AIC licenses.

If you have 90 concurrent calls and they are calling IC at some point, you would definitely need more threads in the thread pool. However, in order to tune it, you need to know for sure what the problem is by looking at the logs and doing monitoring.
