Hi All,

We have an J2EE application deployed on Websphere v6.1 clustered environment and have one another client application which calls this application via RMI transactions.

Therefore, we have a need to do load balancing for RMI transactions. How can we achieve "RMI-IIOP Load Balancing and Failover"? Please share your thoughts.

Thanks,
Ankit

hi Ankit
you can use a mutiple servers in the corbaloc url

corbaloc::server1_boot_strap_port:9812,:server2_boot_strap_port::9813

I'm not sure that it load balances in a round robin fashion but it will failover to the next server in the list if the first is down.

In terms of load balancing this article has some code samples on ejb client calls it randomly picks the corbaloc urls , sort of DIY load balancing

for example
url1=corbaloc::server1_boot_strap_port:9812,:server2_boot_strap_port::9813
url2=corbaloc::server2_boot_strap_port:9813,:server1_boot_strap_port::9812
