Load balancing Java RMI calls
Can the BigIp load balance Java RMI connections?
BigIp LTM upfront, with JBoss web servers as backend clients. Web clients need to communicate with other applications (on backend servers) via RMI calls which we would like to load balance.
Web client <-RMI-> Applications client
How would one set up the virtual server? Is there an article that I can reference?

- hooleylistCirrostratusHi DJ,
- Johan_Linder_10NimbostratusI don't think it's possible with the default setup of RMI. Because in the first request the server sends back it's own IP to the client, thus ignoring the LB after the first connect.
- hooleylistCirrostratusIt would be much more efficient to change the app configuration to reference the VIP address, but you might also be able to rewrite the response content to replace the server IP with the VIP address using an iRule.
- pareklund_70152NimbostratusSo, can anyone confirm whether it is possible or impossible to load balance RMI using Big IP LTM? If the former, could you provide answers to the following questions:
- L4L7_53191NimbostratusHmmm this one looks really tricky. I just had a peek at some RMI overviews and there are several problems that present themselves:
- HamishCirrocumulusA quick look at an RMI whitepaper I found shows that you can force RMI to happen over port 443 or port 80 if you block the direct communications (It's supposed to be automatic I think...
