I have couple of questions. 1. My understanding is DNS Round-robin is for Load sharing and not for load balancing. But Oracle site (Under EJB link) says it is for load balancing. 2. what problem arises when clustering EJB servers ? Thanks

Yes, DNS-RR is Load Sharing, because the load is distributed arbitrarily without any feedback from the components, if a server goes down clients will continue to be directed to it. >2. what problem arises when clustering EJB servers? No problems :-) You only have to follow some rules and use the right appserver. E.g. Websphere cannot replicate HTTPSession, all others can. :-) Regards Roger
