Abstract: Workload adaptation is a process in which a database management system makes use of its resources effectively to meet the performance objectives of workload by filtering and controlling workload requests. Autonomic Workload Management Framework（AWMF） is a general framework for workload adaptation, which lays out the basic components and the important processes for workload adaptation. This paper studies the effectiveness of AWMF for transactional workload. A cost-based queuing network model for transactional workload is developed and used as the performance prediction component for Query Scheduler, a prototype implementation of AWMF. A set of experiments are conducted to verify the effectiveness of Query Scheduler for transactional workload.

Key words: workload adaptation, Autonomic Workload Management Framework（AWMF）, terminal workload, batch workload, transactional workload
