标签：datafile FS orclasm 转换方法 testdg oracle home DATA ASM



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;

 

 

[oracle@rhel6_lhr ~]$ rman target /
