Apache HTTP Server is not responding on 100 User Load

Hi,
We are doing performance test for our product with 100 Users. The application has been deployed on Weblogic 9.2.3 Cluster and configured Apache HTTP server as load balancer.

If I access as single user then it is working fine. But if I give a test with load runner for 100 Users, then after about 60 users are ramped up then the application is responding very slowly.

If I directly access the weblogic deploying bypassing Apache, it is responding normally. Can any one please suggest what can be done.

I have configured the httpd.conf as below





httd-ssl.conf is as below




After some time there is an error saying

I'm afraid that a dump of your httpd.conf file was WAY too long for me to read online.

But what followed it was interesting. I'm not sure offhand if nsapi is part of Apache or not. But it appears that that particular component may be having problems talking back to the client. Either that or you have some sort of downstream server that's supposed to be listening on its port #3263 and is having problems of its own.

Idiot. I should have at least done a quick search before shooting off my mouth. It looks like that's one of the WebLogic cluster servers.

Check the WebLogic logs and see if they have anything to say.
 
I agree. Here's the link: http://aspose.com/file-tools
