    Session Stickness problem on weblogic load balancer

    user12856254

      Hello All

       

      I having trouble related to session stickiness for weblogic load balancing, am using httpclusterservlet on a proxy server that forward requests to 3 managed server that are members of the same cluster.

       

      I tried to search for a solution to this problem and I found two links that are talking about the same problem but there are still not answered!!.

      Here are the links:

      https://forums.oracle.com/message/11158964#11158964

       

      Based on oracle link Using Sessions and Session Persistence, the documentation says under the "HTTP Session Properties" section that there is a change in how the sessions are formatted and this might cause a problem

      for some load balancers (the documentation did not say if weblogic httpclusterservlet is one of them), I tried to do the suggested workaround and I got "java.lang.IllegalStateException: Response already committed" error same as what happens with the user in link https://forums.oracle.com/message/11158966#11158966.

       

      Does anyone knows how to fix this??, I search for a very long time on this problem and with no luck, please help!

          Hi,

           

          Can you please give me some more information about your setup ...

           

          Something like ...

           

          F5/LB --> Apache or OHS --> WebLogic Cluster..

           

          If you are using F5/OHS directly to WebLogic cluster you can try enabling the session persistence and this problem should go away..

           

          If you are using plain Apache or OHS try putting "DynamicServerList" off.

           

          Let me know something more about setup so that i can contribute to help ..thanks.
