| الوصف: | A number of authors have proposed methods for increasing the throughput of transaction processing systems by decomposing transactions into steps and allowing the steps of concurrently executing transactions to be interleaved. In some proposals all interleavings are assumed to be acceptable, while in others certain interleavings are forbidden. In this paper we describe a new concurrency control that guarantees that only the allowable interleavings specified for an application occur The concurrency control is called an assertional concurrency control (ACC). We describe its implementation within the CA-Open Ingres tm database management system and a set of experiments that were run to evaluate its effectiveness using the TPC-C tm Benchmark Transactions. The experiments demonstrate up to 80% improvement for benchmark transactions when lock contention is high, when long running transactions are a part of the transaction suite, and/or when sufficient system resources are prese. |
