摘　　要：远程数据库复制是实现数据容灾的重要技术手段之一,在数据容灾、数据仓库等业务中广泛采用。随着福建省住房公积金数据大集中建设工作的开展,怎样构建一个高效安全的数据库远程复制系统来进行数据的容灾、整合显得尤其重要和迫切。本文详细介绍了Informix数据库远程复制技术,详细阐述了Informix ER的原理、特点、适用模式和部署方式,并总结Informix ER在实际环境中部署、运行和维护的关键要点。Remote database replication offers one of the important means in case of data redundancy and failover. It is widely used in areas such as data redundancy and failover,data warehouse. With the development of the housing accumulation fund data collection work in Fujian province, it appears especially important and urgent to build a safe and efficient database remote replication system for data integration and redundancy and failover. This paper introduces the Informix database remote replication technique in detail, elaborate on its underlying principle, characteristics, application mode and implementation method,and furthermore, summarizes the key points of its implantation、operation and maintenance in real environment.
