• Parallel Transaction Processing(TP) systems have great potential to serve the ever-increasing demands for high transaction processing rate. This potential, however, may not be reached due to the data contention and the widely-used two-phase locking(2PL)Concurrency Control(CC)method. In this paper, a distributed locking-based CC policy called LWDC(Local Wait-Depth Control)was proposed for dealing with this problem for the shared-nothing parallel TP system. On the basis of the LWDC palicy, an algorithm called LWDC_k was designed. Using simulation LWDC_k was compared with the 2PL and the base-line Distributed Wait-Depth Limited(DWDL)CC methods. Simulation studies show that the new algorithm offers better system performance than those comparad.
