用重建控制檔案的方法修改資料檔案路徑
1.檢視資料檔案的路徑：
SQL> col file_name format a55
SQL> set line 120 pagesize 2000
SQL> select file_name,tablespace_name from dba_data_files;
FILE_NAME TABLESPACE_NAME
------------------------------------------------------- ------------------------------
/opt/oracle/db02/oradata/ORCL/test01.dbf TEST
/opt/oracle/db02/oradata/ORCL/test.dbf TEST
/opt/oracle/db02/oradata/ORCL/wacos10.dbf WACOS
/opt/oracle/db02/oradata/ORCL/wacos09.dbf WACOS
/opt/oracle/db02/oradata/ORCL/wacos11.dbf WACOS
/opt/oracle/db02/oradata/ORCL/wacos08.dbf WACOS
/opt/oracle/db02/oradata/ORCL/wacos07.dbf WACOS
/opt/oracle/db02/oradata/ORCL/wacos06.dbf WACOS
/opt/oracle/db02/oradata/ORCL/wacos05.dbf WACOS
/opt/oracle/db02/oradata/ORCL/wacos04.dbf WACOS
/opt/oracle/db02/oradata/ORCL/wacos03.dbf WACOS
/opt/oracle/db02/oradata/ORCL/wacos02.dbf WACOS
/opt/oracle/db02/oradata/ORCL/wacos01.dbf WACOS
/opt/oracle/db02/oradata/ORCL/wacos.dbf WACOS
/opt/oracle/nms/oradata/ORCL/nms01.dbf NMS
/opt/oracle/db02/oradata/ORCL/nms.dbf NMS
/opt/oracle/db02/oradata/ORCL/temp01.dbf TEMP
/opt/oracle/db02/oradata/ORCL/drsys01.dbf DRSYS
/opt/oracle/db02/oradata/ORCL/users01.dbf USERS
/opt/oracle/db02/oradata/ORCL/tools01.dbf TOOLS
/opt/oracle/db02/oradata/ORCL/RBS.dbf RBS
/opt/oracle/db02/oradata/ORCL/indx01.dbf INDX
/opt/oracle/db02/oradata/ORCL/system01.dbf SYSTEM
/opt/oracle/wacos/oradata/ORCL/ts.dbf TS
/opt/oracle/wacos/oradata/ORCL/ipas_event_data.dbf IPAS_EVENT_DATA
/opt/oracle/wacos/oradata/ORCL/ipas_event_idx.dbf IPAS_EVENT_IDX
/opt/oracle/db02/oradata/ORCL/fs.dbf FS
27 rows selected.
2.關閉資料庫修改資料檔案的路徑，將/opt/oracle/db02/oradata/ORCL目錄下的所有資料檔案修改到/opt/oracle/db02/oradata下。
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> !mv /opt/oracle/db02/oradata/ORCL/*.dbf /opt/oracle/db02/oradata/
SQL> !mv /opt/oracle/db02/oradata/ORCL/*.log /opt/oracle/db02/oradata/
3.啟動資料庫到mount狀態下：
SQL> startup mount
ORACLE instance started.
ORACLE instance started.
Total System Global Area 2054195960 bytes
Fixed Size 731896 bytes
Variable Size 570425344 bytes
Database Buffers 1474560000 bytes
Redo Buffers 8478720 bytes
Database mounted.
4.備份控制檔案，在udump目錄下產生trace檔案：
SQL> alter database backup controlfile to trace as '/u01/app/oracle/ctl.txt';
Database altered.
5.編輯產生的ctl.txt檔案，把對應的資料檔案路徑修改後，再將裡面重建控制檔案的語句執行一下：
SQL> shutdown immediate
ORA-01109: database not open
Database dismounted.
ORACLE instance shut down.
SQL> startup nomount
ORACLE instance started.
Total System Global Area 2054195960 bytes
Fixed Size 731896 bytes
Variable Size 570425344 bytes
Database Buffers 1474560000 bytes
Redo Buffers 8478720 bytes

SQL> alter database open;
Database altered.
6.檢視修改後的資料檔案的路徑和狀態：
SQL> select file_name,tablespace_name,status from dba_data_files;
FILE_NAME TABLESPACE_NAME STATUS
------------------------------------------------------- ------------------------------ ---------
