Oracle 数据库迁移数据的建议方法（ASM 到本地硬盘，或者本地硬盘到 ASM）

前一段时间遇到了一个问题，那就是RAC环境下的一个数据文件，竟然放在了本地硬盘，而没有放在ASM磁盘组中。非常怪异的现象，更怪异的是RAC竟然允许这种情况。

其实解决方法很简单，就是使用rman来讲本地的数据文件迁移到ASM磁盘组上。

sql 'alter tablespace xxx offline' ;
backup as copy datafile 39 format '+DATA' ;
switch datafile 39 to copy ;
report schema
sql 'alter tablespace xxx online' ;

因为上面有很多BLOB等信息，但是迁移后发现，对索引或者大对象没有任何影响，，还是比较靠谱的。原来的dba没有变？有待深究。
