新添了盤櫃給oracle服務器，要把原來實例轉移到新的盤櫃上，大概步驟如下：
環境:centOS5.5
原路徑：/oradata/orabak/ (控制文件、數據文件、聯機日誌文件)
新路徑：/oradata/orcl/
步驟：1 關閉數據庫
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
2 將原路徑所有文件拷到新路徑
[oracle@c1 orabak]$ pwd
/oradata/orabak
[oracle@c1 orabak]$ ls
control01.ctl redo02.log system01.dbf undotbs01.dbf
example01.dbf redo03.log temp01.dbf users01.dbf
redo01.log sysaux01.dbf temp02.dbf
[oracle@c1 orabak]$ mv * /oradata/orcl/
[oracle@c1 orabak]$ ll /oradata/orcl
total 1052656
-rw-r----- 1 oracle oinstall 7061504 Oct 27 16:36 control01.ctl
-rw-r----- 1 oracle oinstall 104865792 Oct 27 16:36 example01.dbf

-rw-r----- 1 oracle oinstall 503324672 Oct 27 16:36 system01.dbf
-rw-r----- 1 oracle oinstall 104865792 Oct 27 15:32 temp01.dbf
-rw-r----- 1 oracle oinstall 104865792 Oct 27 15:47 temp02.dbf
-rw-r----- 1 oracle oinstall 36708352 Oct 27 16:36 undotbs01.dbf
-rw-r----- 1 oracle oinstall 5251072 Oct 27 16:36 users01.dbf
3 啓動oracle到nomount,修改control_files的路徑
[oracle@c1 orabak]$ sqlplus / as sysdba

5 啓動數據庫，修改臨時表空間數據文件
SQL> alter database open;
Database altered.
SQL> select file_name,status from dba_temp_files;
FILE_NAME STATUS
------------------------------ ---------------------------
/oradata/orabak/temp02.dbf AVAILABLE
SQL> alter tablespace temp add tempfile '/oradata/orcl/temp01.dbf' reuse;
