Research and Implementation on Middleware of Database Workload Autonomic Adaptation

The workload of the database system is unpredictable and fluctuated rapidly in the network system environment. The load to accept the request and response it is gradually increasing for the database system. This paper proposes and implements a kind of middleware prototype used to adapt the workload of the database system autonomically. The middleware schedules and controls the workload based on the current system performance. It achieves the purpose that it enhances the stability of database system and the total performance of application system. The experiment testified the validity of this middleware.
