4、總結
1、說明
本blog介紹了各種asm資料檔案和filesystem檔案之間的轉換方法，有的記錄了過程，有的沒有記錄過程只記錄了相關程式碼，大家若有興趣可以自行測試。
本次測試的表空間、磁碟組和OS檔案關係如下，文件中不再說明：
|
表空間名 |
磁碟組 |
filesystem檔案 |

testdg |
+DATA/orclasm/datafile/ |
/home/oracle/ |

List of Temporary Files
=======================
File Size(MB) Tablespace Maxsize(MB) Tempfile Name
---- -------- ---------- ----------- ------------------------------------------
1 237 TEMP 32767 +DATA/orclasm/tempfile/temp.264.850260283
2 10 TEMP1 10 +DATA/orclasm/tempfile/temp1.270.853779297
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實現
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
Oracle Database 11g的ASM例項可以直接使用cp命令來實現，從ASM例項的cp幫助資訊上看，已經可以直接從本地資料庫直接cp到遠端資料庫了！
SQL> 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、ASM -> OS
3.1 dbms_file_transfer實現
SQL下執行：
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 ;
SQL> select name,status from v$datafile;

4 總結
以上提供的各種辦法各有優缺點，有的需要重啟資料庫，有的不需要，有的全在rman中執行，有的需要在sql下執行，大家需仔細領悟，如有牛人可以列出表格總結一下各種方法的優缺點我將不勝感激。
