基于RMAN从活动数据库异机克隆(rman duplicate from active DB)

Oracle 11g RMAN能够实现基于活动数据库进行异机克隆，从而省去需要先备份再ftp到辅助服务器的过程。这一切可以全部交给Oracle来搞定。在克隆期间，Oracle会读取Target DB的所有数据结构，无须人为的干预(不同的磁盘系统，文件路径与文件名要指定转换方式)。尽管如此，对于生产环境数据库在整个克隆期间性能会下降，其次...

基于RMAN的异机数据库克隆(rman duplicate)

对于基于生产环境下的数据库的版本升级或者测试新的应用程序的性能及其影响，备份恢复等等，我们可以采取从生产环境以克隆的方式将其克隆到本地而不影响生产数据库的正常使用。实现这个功能我们可以借助rman duplicate方式以及其简单的方式来完成。duplicate方式不同于OS级别的备份，它会为辅助数据库(克隆出来的数据库)生成一个新的d...
