摘要
本文介绍了oracle数据库中的分布式事务概念、二阶段提交机制、IN-DOUBT分布式事务产生的原因及处理方法,同时介绍了基于智能存储技术的容灾系统,并给出了分布式数据库环境的容灾数据库中IN-DOUBT分布式事务的处理实例。
This paper first introduces the concept of in-doubt distributed transactions and two-phase commit mechanism in oracle database as well as the reason for the in-doubt distributed transactions and the method to deal with it.The article then discusses the disaster recovery database based on intelligent storage technology.At last,a demonstration is given for how to deal with in-doubt distributed transactions in disaster recovery database.
