RMAN>

2.3 dbms_file_transfer

create directory asmsrc as'+DATA/orclasm/datafile/';

create directory osdesc as '/home/oracle/';

alter tablespace testdg offline;

exec dbms_file_transfer.copy_file('osdesc','testdg.dbf','ASMSRC','testdg.dbf);

alter database rename file'/home/oracle/testdg.dbf' to '+DATA/orclasm/datafile/testdg.dbf';

alter tablespace testdg online ;

2.4 RMAN convert

rman下：

convert datafile '/home/oracle/testdg.dbf' format '+DATA';

sql 下：

alter tablespace testdg offline ;

alter tablespace testdg rename datafile '/home/oracle/testdg.dbf' to '+DATA/orclasm/datafile/testdg.284.868895277';

recover datafile 14;

alter tablespace testdg online;

2.5 cp命令

11g的asm实例可以直接使用cp命令来实现，从asm实例的cp帮助信息上看，已经可以直接从本地数据库直接cp到远端数据库了！

alter tablespace testdg offline;

[root@rhel6_lhr ~]# cp /home/oracle/testdg.dbf /home/grid/testdg.dbf

[root@rhel6_lhr ~]# chown grid:oinstall /home/grid/testdg.dbf

[root@rhel6_lhr ~]# su - grid

ASMCMD> cp /home/grid/testdg.dbf +DATA/orclasm/datafile/testdg.dbf

copying /home/grid/testdg.dbf -> +DATA/orclasm/datafile/testdg.dbf

ASMCMD>

alter database rename file'/home/oracle/testdg.dbf' to '+DATA/orclasm/datafile/testdg.dbf';

alter tablespace testdg online ;
