### replica handler

A replica handler is responsible for load balancing and failover for a replica-aware stub. The replica handler maintains a list of available replicas and chooses a replica for execution when a remote invocation is made on the replica-aware stub. You choose one of WebLogic's built-in replica handlers by setting various flags for RMI and EJB compilation; these flags affect how the replica handler treats such service characteristics as failures and retries, and server affinity.
