双机同步热备方法研究

随着对系统工作可靠性的要求越来越高，双机在线热备在多个工程项目中广泛采用，继而对双机数据同步和在线数据备份也提出了相关需求，根据工程中的实际需求，针对双机数据同步和数据在线备份的解决方法做了深入的研究。通过对Oracle数据库的深入学习，利用Oracle数据库的数据能够根据约束条件实现分区存储的特点，提出了一种双机数据同步，数据库存储数据在线备份的解决方案，为相关人员提供了极有价值的参考信息和有效方法。

Method of Hot Backup System for Duplicated Equipment

Since the requirement for operational reliability of computer system becomes better and better, the technology of Computer Duplex working online backup is adopted diffusely in many engineering projects, the related capability such as processing data synchronization and data online backup is demanded then. Based on the characteristics of partitioned space allocation storage up to the constraint condition in Oracle database, a new effectual scheme is brought forward by author. This paper describes the detailed research on how to the resolve these two problems in practical design and application, which may provide valuable reference.
