Conflict-free Concurrency Control Protocol Based on Function Alternative Model
Hui Chen · Jisuanji gongcheng · 2010
Aiming at the function alternative model of the periodic transaction,Conflict-free Concurrency Control Protocol for Supporting Periodic transaction(SP-CCCP) which is based on CCCP,adds the compatible test between the new transaction and its future active periodic transaction with higher priority,and improves the performance of compatible test between the new transaction and the current active transaction.SP-CCCP selects the compatible alternative which has no conflict with other transactions,and improves success ratio of the system transaction and utilization ratio of the CPU.Simulation results show that in most situations,the performance of SP-CCCP is better than CCCP.
