On integrating control algorithms for buffer management and concurrency for parallel transaction processing systems

[[abstract]]The performance of multi-processor based data sharing complex for transaction processing can be enhanced through the use of an integrated concurrency-coherency-recovery protocol. This protocol, combined with the use of shared main memory buffer, can allow early commit of transaction updates, reduce multi-system coupling overhead, and eliminate the unnecessary disk updates in transaction processing in normal time. Results obtained from performance simulation study show a significant improvement in the maximum transaction throughput can be sustained if this integrated protocol is used[[fileno]]2030118030007[[department]]電機工程學
