本文转自:乐沙弥的世界 对于物理损坏的数据块,我们可以通过RMAN块介质恢复(BLOCK MEDIA RECOVERY)功能来完成受损块的恢复,而不需要恢复整个数据库或所有文件来修复这些少量受损的数据块.恢复整个数据库或数据文件那不是大炮用来打蚊子,有点不值得!但前提条件是你得有一个可用的RMAN备份存在,因此,无论何时备份就是一切.本文演示了产生坏块即使用RMAN实现坏块恢复的全过程. 1.创建演示环境 SQL; BANNER ---------------------------------…

rman作为oracle备份与恢复工具,为我们提供了强大的功能.当中包含对数据文件的物理和逻辑检測以及备份文件的有效性检測. 首先.来看一下rman对数据文件的检測. 我们知道,rman在备份数据时,会将数据读入读缓存,然会将数据从读缓存写入写缓存并终于写入数据库.在从读缓存到写缓存的过程中,rman会进行物理一致性的检測(db_block_checksum未true)和逻辑一致性检測(使用了check logical选项).比如: SQL> show parameter db_block NA…
