Abstract

A family of locking-based protocols is analyzed that use a novel mode of locks called ordered sharing. Using a centralized database simulation model, it is demonstrated that these protocols exhibit comparable performance to that of traditional locking-based protocols when data contention is low and exhibit superior performance when data contention is high. It is shown that the performance of these protocols improves as physical resources become more plentiful. This is particularly significant since two-phase locking degrades due to data and not resource contention. Thus, introducing additional resources improves the performance of the proposed protocols while it does not benefit two-phase locking significantly.
