【ASM】ASM数据文件和OS文件（FILESYSTEM）转移方法总结

blog文档结构图：

1 说明

本blog介绍了各种asm数据文件和filesystem文件之间的转换方法，有的记录了过程，有的没有记录过程只记录了相关代码，大家若有兴趣可以自行测试。

本次测试的表空间、磁盘组和os文件关系如下，文档中不再说明：

表空间名	磁盘组	filesystem文件
testdg	+DATA/orclasm/datafile/	/home/oracle/

用的数据库环境：

SQL> select * from v$version;

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 ;

3.1 dbms_file_transfer实现

SQL下执行：

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

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

alter tablespace testdg offline;

exec dbms_file_transfer.copy_file('ASMSRC','testdg.282.868891371','osdesc','testdg.dbf');

alter database rename file'+DATA/orclasm/datafile/testdg.282.868891371' to '/home/oracle/testdg.dbf';

alter tablespace testdg online ;

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;

4 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，如有牛人可以列出表格总结一下各种方法的优缺点我将不胜感激。
