基于Oracle 10g的Rman备份与恢复优化

RMAN Backup,Recovery and Optimization Based on Oracle 10g

目的:实现基于Oracle 10g数据库的快速备份与恢复。方法:使用Oracle 10g自带的Rman工具,充分利用、挖掘Oracle 10g的新特性,在测试环境下反复演练,寻找最佳备份恢复方案。结果:在不升级硬件的条件下,成功实现Ora-cle 10g数据库的快速备份与恢复。结论:通过对Rman工具参数合理配置和备份方案优化选择,可以提高备份恢复效率,加快数据库日常备份速度和故障时的快速恢复能力,提高数据库的高可用性。

Objective To realize rapid backup and recovery based on Oracle 10g.Methods The optimal backup recovery scheme was developed on the bases of RMAN tool and new characteristics of Oracle 10g.Results The rapid backup and recovery of Oracle 10g database were realized without the hardware upgrade.Conclusion Scientific configuration of RMAN parameters and optimized backup scheme contribute a lot to the enhancement of backup recovery and availability of the database.
