Hi there,
what load balencing algorithms does websphere use? With my little knowledge in weblogic, I know that it uses Round-robin, Randon and weight based load balencing algorithms. dose websphere uses the same, what is the default algorithm and how can we set it.
Thanks in advance.

WAS Ver 4.0.1 uses Round Robin, Random, Random prefer local and Round Robin Prefer Local.
These settings are configured in the ServerGroup Properties.

Just to be a bit provocative, I'll add that WL does not perform load balancing, it performs load distribution.
I'll back this statement up with the following definitions. Load balancing implies that load is evenly distributed across a set of servers. Load distribution is the blind assignment of work to a server. Since RR assigns work blindly, it does not balance, rather it distributes work load.

It is sorta covered in the JavaRanch Style Guide.
