支持自组织长事务模型的EAI引擎并发调度研究及实现

Research and Realization of Concurrent EAI Engine Construction Supporting Selforganized Long Transaction Model

针对传统长事务处理过程中所表现出的效率低下,操作步骤烦琐复杂且不易实现的不足,提出了一种自组织长事务并发控制模型。该模型允许事务内部结构和同步关系的自主建模,并通过EAI引擎运行期自行解析事务内部结构,以提高EAI引擎的执行并发度,保证事务执行遵循正确时序,并减少了冲突和回滚。最后给出了一个利用该模型实现的企业应用集成原型系统。

Traditionally, two limitation of the long-transaction mechanism are low efficiency and difficulty of realization. A self-organized transaction model is adopted as a solution to this problem, The proposed model admits enterprises to design inner-nested constructions and synchronous relations among different jobs which belong to long transaction. In order to improve efficiency of execution, EAI engine analyzes the inner constructure of transaction automatically in running state, It can also confirm the correct execution order and reduce the conflicts and rollbacks, A prototype system is given, which implements EAI system by utilizing this model.
