Performance Evaluation of Real-Time Locking Protocols Using a

Real-time systems must maintain consistency while minimizing the number of tasks that miss the deadline. To satisfy both the consistency and real - time constraints, there is the need to integrate synchronization protocols with real-time priority scheduling protocols. One of the reasons for the difficulty in developing and evaluating database synchronization techniques is that it takes a long time to develop a system, and evaluation is complicated because it involves a large number of system parameters that may change dynamically. This paper describes a prototyping environment for investigating distributed realtime database systems, and its use for performance evaluation of priority-based locking protocols for real-time database systems.
