Load balancing in an EAServer cluster is determined by three factors, each of which is discussed in detail in this section:
Load metrics – if you select a dynamic load policy, the load metrics determine the load on your servers and give each server a numerical weighting, which is then used to distribute incoming client requests and optimize performance of the cluster.
Load distribution policy – when you configure load balancing, you select the distribution policy that best matches your environment and situation.
Interoperable object reference (IOR) – contains a profile that the client uses to look up a component. The profile contains the server and port number that the client uses to access the component. The distribution policy determines the order in which the profiles are distributed to the clients.
