| 摘 要： | 在Client/Server系统中,服务器的可用性是提高整个系统可用性的关键,采用多复制服务器是提高系统可用性的最有希望的手段.但是,复制数据更新过程中的阻塞问题是整个系统性能的一个瓶颈.本文提出一种无阻塞的多服务器独立提交的复制数据更新方法,对于因失效不能完成更新的服务器采用协调机制使其达到相同的最终状态.

| Abstract: | The availability of server is a key factor in improving client/server system performance. The most promising approach in this regard is to use multiple replicated servers. However, the blocking problem is a bottleneck in replicated data update for this approach. In this paper, a non-blocking independently replicated data update method and a reconciliation mechanism to reach agreement at those servers not committed because of the failure are presented. |
