A system and method for a highly available timer service may include a timer database operable to store information on one or more timers. The system may further include a plurality of servers in a cluster, each server containing a failure detection service, a timer service and one or more applications. In one embodiment, each application may be operable to request and process one or more timer notifications from the timer service contained in the same server. Each failure detection service may also be operable to detect a failure of other servers in the cluster. In addition, each timer service may be operable to retrieve information on the one or more timers from the timer database, and to provide a timer notification to any application in the cluster in response to a notification from the failure notification service that a server has failed.

System and method for highly available timer service in a J2EE cluster

A method, apparatus, and system for providing a standard, generic contract between an application server and a message provider which allows the message provider to deliver messages to message endpoints (each of which is associated with a corresponding message application) residing in the application server is disclosed. By generic, it is meant that the contract is independent of the specific messaging style, messaging semantics and messaging infrastructure used to deliver messages. In this way, the contract also serves as the standard message provider pluggability contract that allows any message provider to be plugged into any application server via an associated resource adapter.
