A cluster manager application program library includes an event handler to communicate an event from an application server instance to which the library is linked to a message server in a cluster of application server instances. The library further includes a notification handler to receive at the application server instance a notification of an event in the cluster from the message server, and a message server communication handler to exchange messages between the application server instance and other application server instances in the cluster via the message server.
