one of our customers has a Domino web server (9.0.1FP1 64bit, Windows 2008 R2) which serves 5 XPages-based web applications (each with a dedicated IP address). Users can access these applications directly with the corresponding URL but also with a lot of different aliases which are mapped to the NSF of one of the main applications. Now we would like to implement HTTP clustering (failover only) and I wonder if ICM can be used at all in this scenario. If I get all the available documentation right, ICM works with only one URL but that is no option for our case. Can ICM be configured to work in this scenario? A Domino-based solution would be preferred but if there is no way to use ICM we will look for a different solution.
The Internet Cluster Manager does not provide failover, its a load balancer.
It routes internet traffic to the most available webserver in the cluster based off the Server Availability Index (SAI)
If the backend cluster server suddenly goes down, the web browser has no idea to be redirected to its cluster mate, (unless a new request gets routed to the ICM)
The ICM task doesn’t provide redundancy to itself…what happens when your ICM server goes down?
Sounds like for your task you’re be better serviced by a load balanced proxy sever or IP sprayer
I know IBM Mobile Connect (IMC) another product has some preset filters for Sametime, iNotes and Traveler, not sure if has any optimization’s for Xpages
