Today’s mission critical applications require highly available services. WebLogic Server offers messaging, transaction, and other system services to facilitate building enterprise grade applications. These services can operate in a clustered environment to help build scalable and highly available applications. Previous releases provided support for administrators to manually migrate highly available services from a failed cluster server to a healthy server. Oracle WebLogic Server 10.3 adds support to the WLS Clustering infrastructure to automatically migrate the services without any administrative intervention. The authors present various elements of the automatic service migration framework in general, followed by detailed explanations and best practices.
