Abstract
A computer implemented method, apparatus, and computer usable program code for load balancing in a cluster. In response to receiving a notification of an impending state change event in the server, a weight adjustment value for a server is identified to form an identified weight adjustment. An adjusted routing weight for the server is generated using the identified weight adjustment to form a current routing weight for the server. An incoming service request is routed to a selected server in the cluster using current routing weight associated with servers in the cluster.
