Abstract :
The authors examine a priority-driven locking protocol called integrated real-time locking protocol. They show that this protocol is free of deadlock, and in addition, a high-priority transaction is not blocked by uncommitted lower protocol. They show that this protocol is free of deadlock, and in addition, a high-priority transaction is not blocked by uncommitted lower priority transactions. The protocol does not assume any knowledge about the data requirements or the execution time of each transaction. This makes the protocol widely applicable, since in many actual environments such information may not be readily available. Using a database prototyping environment, it was shown that the proposed protocol offers a performance improvement over the two-phase locking protocol
