多库系统的两阶段局部代理失败恢复策略

从保证全局事务的ACID性及实际的可操作性出发，提出了一种较为可靠的两阶段局部代理的工作流程，使用局部代理作为全局事务管理系统与局部数据库的中间层，模拟出符合2PC协议的状态，从而在多数据库的事务处理中使用2PC协议，在最大限度保证异构数据库自治的前提下，从一定程度上解决了全局事务的原子性保证问题和局部站点失败恢复的问题

Failure Recovery Method of 2 Phase Local Agent for Multidatabase

This paper provides a comparatively more dependable workflow of 2 phase local agent, ensuring the ACID of global transaction and its practicability. The author uses local agent as the middle layer for global transaction manager and local database, models a state corresponding to 2PC protocol and applies 2PC protocol in multidatabase transaction processing. This method, to some extent, solves the problems of atomicity in global transaction and failure recovery in local station, under the premise that it can guarantee the autonomy of heterogeneous multidatabase to the maximum.
