All, I am looking for some document which helps me to tune Apache 2.2. Can you please help me? Here is my actual problem; We have a plug-in (Oracle Access Manager - WebGate) which is installed on this Apache 2.2 which intercepts all the requests that hit the Apache. The plug-in communicates with a service (Oracle Access Manager - Access Server) in another machine. We are doing a load test with 10k users. The plug-in works fine till the load reaches 2k. Then we start getting weird errors in 'error_log' as the plug-in couldn't connect to service. I am looking this issue in 2 angles. 1) from the plug-in 2) from apache server. I need your help in tuning the Apache in a better way. Thanks A * R
