Ø "For example, if users have a floating license, they can potentially allocated a floating license on each server that their request is sent to."
Just to clarify, one user takes one floating token within a server group - even if there are individual requests from the same user to each server in a server group. So no matter how many different servers in a server group that user accesses, they'll get one token. There is logic in the system that stores logged in users in a table that the various servers can coordinate from. Thus, I do not believe that scenario can actually happen. Maybe I'm misunderstanding the scenario... -David J. Easter Manager of Product Management, Remedy Platform BMC Software, Inc.

If you have a session infinity set at the LB on in front of the ARServers then there is no difference that having each midtier bypassing the LB and going straight to the ARServer instance. E.g. mt1 to AR1, mt2 to AR2 etc I don't think anyone would want to implement something that could take more than one floating license at one time though Axton right?

Since the AR System server uses an ONC-RPC implementation that is layered on top of TCP/IP, AR System server traffic can be load balanced. Because of the nature of the client/server interaction within AR System, the "sticky" option is required. This reduces the balancing that can occur, but still allows for the spreading of the workload from multiple clients.

However, there are trade-offs. For example, if users have a floating license, they can potentially allocated a floating license on each server that their request is sent to. This statement does not apply to the mid-tier layer though. The J2EE container in use has session information stored that is required to handle requests from a user. If the user is re-directed to a mid-tier server where this session information is not available, the user will fail authentication and will be redirected to the login interface.
