Any load balancer geeks out there?
Tags: Load balancing Domino
In a customer's project we've got a question regarding load balancing. And I hope that someone of you is able to give us a short answer.
We're using a Nortel Application Switch 2424 in front of our 3 Domino web servers. We need balancing with session persistance, to assure that a single user only uses a single server for it's session. This configuration is working without any problems. But we need someting more:
Only one of our three server hosts the application archive. And if a user sends a request to the archive, the balancer must forward this request to this special server (URL based redirection), regardless of the other two rules.
Our load balancer expert told us, that this is not possible. We only have the choices between
(a) balancing and session persistance or
(b) URL based redirection.
The documentation is not very clear on those topics, espacially regarding the combination of features. Our opinion is, that building different server groups (one for the application with all 3 servers and one for the archive with only one server) should do what we want to. But unfortunately we are not able to access the load balancer by our selves to do any tests, because it is in the hands of another department. So if you have any ideas, please share them with us. Thanks a lot!

What you should do in this case is. Create on the 2 servers which are not hosting the arcive a redirection rule to the one server which has the arcive.
Make sure you have SSO enabled between the 3 servers.
Configure on the Load Balanching device an extra host with the name to whome you are redirecting and only couple the one server to that jhost which hold the arcive database
Note : make sure that the hostname to whom you want to redirect is in the same domain as where your 3 servers are running otherwise SSO will not work.
Hope you understand what I mean otherwise you can send me an email and i will try to help you further.
Kind Regards
