1.镜像备份:多数系统通过control_files参数(*.control_files在PFILE或者SPFILE中)指定多路控制文件,在某种意义上也是起到了备份的效果 2.RMAN自动备份: 可以设置configure controlfile autobackup on来开启自动备份的功能,另外,即使不开启此功能,oracle每当备份数据文件(system表空间)的时候也会把控制文件备份(这个和备份...

听说过Oracle 控制文件,还有快照控制文件这个说法呢?没错,尽管快照控制文件很少被提及,但确实是存在,只不过在使用RMAN时这个快照控制文件被使用。回顾一下Oracle 控制文件,我们知道控制文件是Oracle体系结构中的重要组成部分之一,记录了当前数据库的结构信息,同时也包含数据文件及日志文件的信息以及相关的状态,归档信息,也...
