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。
主要采用set newname、convert datafile、dbms_file_transfer.copy_file、backup as copy datafile、alter database rename file这几种办法。
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：

dbms_file_transfer（推荐）
1 2 3 4 5 6 | 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 ; |
RMAN convert（推荐）
rman下：
1 | convert datafile '/home/oracle/testdg.dbf' format '+DATA'; |
必须为归档模式，否则会报错：ORA-19602: cannot backup or copy active file in NOARCHIVELOG mode
sql 下：
1 2 3 4 | 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; |
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！
1 2 3 4 5 6 7 8 9 10 | 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 ; |
copy + switch
1 2 3 4 5 6 7 | sql "alter database datafile 8 offline"; recover datafile 8; run { copy datafile '/home/oracle/a.dbf' to '+data'; } run { switch datafile '/home/oracle/a.dbf' to datafilecopy '+DATA/gbk/datafile/test.302.1120761841'; } sql "alter database datafile 8 online"; |
