no details config, no answer
im sorry for reply an old post, but im getting the same error and i though that you could help me.
In my case, im tunning jboss and stress my app whith jmeter. I have to score 300 simultaneous access.
For that, i have 2 jboss running and 1 apache (mod_cluster) doing load balancer.
Analysing the results with 120 access i get
Caused by: javax.resource.ResourceException: Unable to get managed connection for
But the number of connections in use, is not on top. (im using JON to monitory connections)
So... i think that it shoul probably be the number of threads.
The scenario there is when I am trying to execute transaction for max no of threads. The threads are unable to get the connection and it gives a error.
Anyone can give me an advice or tips for tunning apache?
I think that apache that is limiting that. What you think?
Just closing my thread for a future guys...
In my case, the real problem has nothing related about my last post.
I was wrong when i believed in DBA.
He said that the Postgresql has no limit connections, but it was setted for 100 only.
So, the error appears...
When increase this number... all problemas has gone!
Thx for all
