摘　　要：对传统高级事务模型Saga进行扩展和改进的高级事务模型ESaga,建立在CORBA对象事务服务模型(OTS)基础之上.不仅为Saga模型增加了分布式事务支持,而且应用多A-gent技术进行优化,很大程度上弥补了Saga模型补偿事务过于复杂的不足,使Saga模型能够应用到现实工作流系统中解决长事务问题.现给出与ESaga模型实现相关的平台,长事务处理接口定义,事务Agent的部分定义、算法,及其验证结果.An Long Lived Transaction(LLT)Esaga model which based on traditional LLT Saga model is built on the basis of Object Transaction Service of CORBA.ESaga enhanced the distributed transaction support for Saga,and optimized Saga by Agent technology.The improvements covered the shortage of Saga whose compensation affairs are too complex and made Saga model can be applied to a real workflow system to solve LLT problems.An implementation platform of ESaga,the processing interface,part of the Agent definition and algorithm of LLT Esaga model are given.Finally,the validation results of LLT Esaga model are provided.
