1.迁移数据文件到ASM 
1）数据库一致性情况下迁移: 
将数据库启动到mount状态,生成rman copy 语句,然后在rman中执行: 
SQL> startup mount 
SQL> select q'(copy datafile ')'||name||q'(' to '+oradata';)' from v$datafile; 
Q'(COPYDATAFILE')'||NAME||Q'('TO'+ORADATA';)' 
------------------------------------------------------------------------------- 
copy datafile 'D:\NSOADP\SYSTEM01.DBF' to '+oradata'; 
copy datafile 'D:\NSOADP\SYSAUX01.DBF' to '+oradata'; 
copy datafile 'F:\NSOADP\UNDOTBS01.DBF' to '+oradata'; 
copy datafile 'D:\NSOADP\USERS01.DBF' to '+oradata';

rman target / 
RMAN> run 
2> { 
3> copy datafile 'D:\NSOADP\SYSTEM01.DBF' to '+oradata'; 
4> copy datafile 'D:\NSOADP\SYSAUX01.DBF' to '+oradata'; 
5> copy datafile 'F:\NSOADP\UNDOTBS01.DBF' to '+oradata'; 
6> copy datafile 'D:\NSOADP\USERS01.DBF' to '+oradata'; 
7>} 
启动 backup 于 2015-04-15 10:02:44 
使用通道 ORA_DISK_1 
通道 ORA_DISK_1: 启动数据文件副本 
输入数据文件: 文件号=00001 名称=D:\NSOADP\SYSTEM01.DBF 
输出文件名=+ORADATA/nsoa/datafile/system.260.877082571 标记=TAG20150415T100250 RECID=265 STAMP=877082603 
通道 ORA_DISK_1: 数据文件复制完毕, 经过时间: 00:00:35 
完成 backup 于 2015-04-15 10:03:25

生成更改控制文件数据名的语句,然后执行更改: 
SQL> SELECT --T.NAME,T.FILE#,C.FILE#,C.NAME 
  2  q'(ALTER DATABASE RENAME FILE ')'||c.name||q'(' to ')'||t.name||q'(';)' 
  3   FROM V$DATAFILE_COPY T LEFT JOIN V$DATAFILE C 
  4  ON T.FILE#=C.FILE# 
  5  WHERE T.NAME IS NOT NULL  order by COMPLETION_TIME desc;

SQL> alter database rename file 'D:\NSOADP\SYSTEM01.DBF' to '+ORADATA/nsoa/datafile/system.260.877082571'; 
....

2)数据库非一致性情况下迁移(归档模式): 
使用alterdatabase datafile '' offline命令将数据文件offline,然后同上面的方式一样处理,最后将数据文件online 
SQL> alter database datafile '/u01/oradata/sydb/user01.dbf' offline;

RMAN> copy datafile '/u01/oradata/sydb/user01.dbf' to '+oradata';

Starting backup at 23-APR-15 
using target database control file instead of recovery catalog 
allocated channel: ORA_DISK_1 
channel ORA_DISK_1: SID=180 device type=DISK 
channel ORA_DISK_1: starting datafile copy 
input datafile file number=00004 name=/u01/oradata/sydb/user01.dbf 
output file name=+ORADATA/sydb/datafile/users.257.877803115 tag=TAG20150423T181155 RECID=1 STAMP=877803123

SQL> alter database datafile '+ORADATA/sydb/datafile/users.257.877803115' online; 
alter database datafile '+ORADATA/sydb/datafile/users.257.877803115' online 
* 
ERROR at line 1: 
ORA-01113: file 4 needs media recovery 
ORA-01110: data file 4: '+ORADATA/sydb/datafile/users.257.877803115' 
SQL> recover datafile '+ORADATA/sydb/datafile/users.257.877803115'; 
Media recovery complete. 
SQL> alter database datafile '+ORADATA/sydb/datafile/users.257.877803115' online;

2.迁移日志文件到ASM 
可以在mount或open状态迁移非current或active日志文件到asm;方法将已有的日志文件(每个日志组必须有一个member)或日志组 
(数据库必须有两个日志组存在)删除,然后添加新的日志文件或日志组; 
alter database drop logfile member 'E:\NSOADP\REDO07.LOG';  #删除日志文件 
alter database drop logfile group 2;  #删除日志组 
alter database add logfile member '+oradata' to group 7;   #添加日志文件 
alter database add logfile ( '+oradata','oradata') size 50m;  #添加有两个成员的日志组 
alter database add logfile '+oradata','oradata' size 50m;  #同时添加两个日志组

3.迁移控制文件到ASM 
首先确定好控制文件位置和名称 
SQL> show parameter control_file 
NAME                                 TYPE        VALUE 
------------------------------------ ----------- ------------------------------ 
control_file_record_keep_time        integer     7 
control_files                        string      F:\NSOADP\CONTROL01.CTL

修改control_files初始化参数值为asm,然后重启数据库到nomount状态: 
SQL> alter system set control_files='+oradata' scope=spfile; 
SQL> shutdown immediate; 
SQL> startup nomount

使用rman复制当前的控制文件到asm 
rman target / 
RMAN> restore controlfile from 'F:\NSOADP\CONTROL01.CTL'; 
启动 restore 于 2015-04-22 09:40:30 
使用目标数据库控制文件替代恢复目录 
分配的通道: ORA_DISK_1 
通道 ORA_DISK_1: SID=70 设备类型=DISK

通道 ORA_DISK_1: 已复制控制文件副本 
输出文件名=+ORADATA/nsoa/controlfile/current.314.877686033 
完成 restore 于 2015-04-22 09:40:39 
复制代码 
注:如果使用备份的控制文件进行还原,而数据库以前有过RESETLOGS操作或创建控制文件时创建语句指定了RESETLOGS,则必须以RESETLOGS方式打开数据库。 
SQL> alter database mount; 
SQL> show parameter control_file

NAME                                 TYPE                   VALUE 
------------------------------------ ---------------------- ------------------------------ 
control_file_record_keep_time        integer                7 
control_files                        string                 +ORADATA/nsoa/controlfile/curr 
                                                            ent.314.877686033 
SQL> alter database open;
