摘要
Abstract
Based on new characters of embedded hybrid real-time transaction concurrency control,a hybrid concurrency control algorithm,namely mixed concurrency control-CCCP(MCC-CCCP),was proposed by adding substitution and compensation.Conflict was divided into the intra-class and inter-class in the algo-rithm.ET-CCCP protocol solved the intra-class conflict of hard real-time transaction,while CCCP protocol solved the intra-class conflict of soft real-time transaction.The LC-CCCP algorithm was designed to resolve the inter-class conflicts by comparing to select the least number of alternative involved in the concurrency control and taking some compensation measures to reduce the number of conflicts.Simulation experiments showed that the hybrid algorithm decreased the rate of restart and transaction miss,which had certain ad-vantages.关键词
