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 ;
