rman对特定表空间迁移技术-tutoriel mysql-php.cn

今天是2014-01-13，今天收到朋友一条qq消息，说是看一下备份数据迁移问题。问题描述：生产有两个库A和B，A库是生产库，B库为测试库，且A库有3个表空间1,2，3，且只有1表空间为生产表空间数据量较小，其他两个表空间为测试且数据量非常大。当A库突然宕机，

今天是2014-01-13，今天收到朋友一条qq消息，说是看一下备份数据迁移问题。

问题描述：

生产有两个库A和B，A库是生产库，B库为测试库，且A库有3个表空间1,2，3，且只有1表空间为生产表空间数据量较小，其他两个表空间为测试且数据量非常大。当A库突然宕机，需要通过之前备份将A库的1表空间及时恢复到B库，以此来担任业务，为了尽快恢复数据，需要把2和3表空间排除掉，技术需要采用rman。

解决方案：

哈哈。我第一次听到这么样的情景，因为这种情况完全可以通过dg来解决此问题，另外对于该问题还可以使用expdp和impdp以及传输表空间技术来实现。

本例只是为了帮他测试，使用rman技术来完成此需求。

操作步骤：
