ASM数据文件和FS之间的各种转换方法（4）
作者：互联网
1.3 rman convert +open状态
使用rman的convert命令来实现，同样适用于10g
rman下：
convert datafile '+DATA/orclasm/datafile/testdg.277.868887219' format '/home/oracle/testdg.dbf';
sql下：
alter tablespace testdg offline ;
alter tablespace testdg rename datafile '+DATA/orclasm/datafile/testdg.277.868887219' to '/home/oracle/testdg1.dbf';
recover datafile 14;
alter tablespace testdg online;

2 总结
以上提供的各种办法各有优缺点，有的需要重启数据库，有的不需要，有的全在rman中执行，有的需要在sql下执行，大家需仔细领悟。
