rac环境将误建立在本地目录的数据文件转移到ASM存储中。

+DATA/hyw/datafile/undotbs2.265.903803821                                  5 ONLINE  UNDOTBS2


SQL> create tablespace tdb datafile '/u02/app/oracle/datafile/tdb.dbf' size 10m autoextend off;  //模拟添加数据文件
  
Tablespace created.




将数据文件offline  
SQL> alter database datafile 6 offline;  
  
Database altered.


使用RMAN移动本地文件到asm  
  
RMAN> copy datafile '/u02/app/oracle/datafile/tdb.dbf' to '+DATA';  
  
Starting backup at 03-FEB-16  
using target database control file instead of recovery catalog  
allocated channel: ORA_DISK_1  
channel ORA_DISK_1: SID=35 instance=orcl1 device type=DISK  
channel ORA_DISK_1: starting datafile copy  
input datafile file number=00006 name=/u02/app/oracle/datafile/tdb.dbf  
output file name=+DATA/orcl/datafile/tdb.268.902813699 tag=TAG20160203T053456 RECID=1 STAMP=902813699  
channel ORA_DISK_1: datafile copy complete, elapsed time: 00:00:03  
Finished backup at 03-FEB-16 


注册一下
RMAN> switch datafile '/u02/app/oracle/datafile/tdb.dbf' to copy;

将数据文件online  
SQL> alter database datafile 6 online;  
  
Database altered. 


检查数据文件
select file_name,file_id,ONLINE_STATUS,tablespace_name from dba_data_files;




-------------------------系统表空间


alter tablespace system add datafile '/home/oracle/scripts/00.dbf' size 10m autoextend off;  //模拟添加数据文件


SQL> alter database datafile 6 offline;  
alter database datafile 6 offline  
*  
ERROR at line 1:  
ORA-01541: system tablespace cannot be brought offline; shut down if necessary --这就是为什么需要停机时间 


在一个节点执行：  
  
SQL> shutdown immediate  
Database closed.  
Database dismounted.  
ORACLE instance shut down.


另一个节点：  
SQL> select open_mode from gv$database;  
  
OPEN_MODE  
--------------------  
READ WRITE


5.使用asmcmd将本地文件移动到asm  
ASMCMD [+data/orcl/datafile] > cp /home/oracle/scripts/00.dbf +DATA
copying /home/oracle/scripts/00.dbf -> +DATA/hyw/datafile/00.dbf  
  
6.启动数据库到mount状态  
SQL> startup mount;  
ORACLE instance started.  
  
Total System Global Area 1336176640 bytes  
Fixed Size                  2213136 bytes  
Variable Size             587205360 bytes  
Database Buffers          738197504 bytes  
Redo Buffers                8560640 bytes  
Database mounted.  
  
7.修改数据文件路径  
SQL> alter database rename file '/home/oracle/scripts/00.dbf' to '+DATA/hyw/datafile/00.dbf';
  
Database altered.  
  
8.启动数据库  
  
SQL> alter database open;  
  
Database altered.  
  
9.检查数据文件状态  
节点一：  
  
FILE_NAME                                                            FILE_ID ONLINE_ TABLESPACE_NAME
----------------------------------------------------------------- ---------- ------- -------------------------
+DATA/hyw/datafile/users.259.903803203                                     4 ONLINE  USERS
+DATA/hyw/datafile/undotbs1.258.903803203                                  3 ONLINE  UNDOTBS1
+DATA/hyw/datafile/sysaux.257.903803203                                    2 ONLINE  SYSAUX
+DATA/hyw/datafile/system.256.903803201                                    1 SYSTEM  SYSTEM
+DATA/hyw/datafile/undotbs2.265.903803821                                  5 ONLINE  UNDOTBS2
+DATA/hyw/datafile/00.dbf                                                  6 SYSTEM  SYSTEM  
  
节点二：  
SQL> select file_name,file_id,ONLINE_STATUS,tablespace_name from dba_data_files;  
ERROR:  
ORA-01157: cannot identify/lock data file 6 - see DBWR trace file  
ORA-01110: data file 6: '+DATA/hyw/datafile/00.dbf'  
  
10.所以最后一步，是要重启节点二  
  
SQL> shutdown immediate  
Database closed.  
Database dismounted.  
ORACLE instance shut down.  
SQL> startup  
ORACLE instance started.  
  
Total System Global Area 1336176640 bytes  
Fixed Size                  2213136 bytes  
Variable Size             486542064 bytes  
Database Buffers          838860800 bytes  
Redo Buffers                8560640 bytes  
Database mounted.  
Database opened.  
  
11.检查数据文件
