摘要
双机热备份系统是目前服务器端广泛应用的容错技术。但是,一般成熟的应用于大型企业的双机热备份方案,由于软硬件成本过高,并不适用于中小型企业网络。本文提出了一种基于分布式事务的纯软件方式的数据库双机热备份方案,它抛弃了传统的磁盘阵列作为共享存储,而是使用分布式事务的方法,把数据存放在两台服务器上,并且保证它们的一致。
Dual hot-backup system is a widely used technology for servers. But because normal dual hot-backup program for large enterprises requires software and hardware that costs too much,small and media enterprise network cannot afford that. This paper proposes a hot-backup program for database based on distributed transaction which is working in pure software mode. It doesn ＇t require a disk array as the shared storage,but store data on both servers using distributed transactions,and keep them consistent.
