本方式是利用已有的建立好的數(shù)據(jù)庫，直接改相關(guān)配置文件到新的盤符。
前提，數(shù)據(jù)庫已正常運行。
可以考慮：用不同的sid在d盤建好庫。
以下內(nèi)容弄明白了以后可以直接制作sql文件，用sqlplus直接調(diào)用

一、連接數(shù)據(jù)庫
sqlplus /nolog
SQL>connect /as sysdba

二、create pfile from spfile;
備注：這是會生成一個文件，在$oracle_home/dbs中，文件名稱是init<SID>.ora

三、查詢相關(guān)要復(fù)制的文件
SQL> select name from v$datafile;
SQL> select name from v$tempfile;
SQL> select name from v$controlfile;
SQL> select member from v$logfile;

(1)SQL> select name from v$datafile;

NAME
--------------------------------------------------------------------------------
/u01/app/oracle/oradata/orcl/system01.dbf
/u01/app/oracle/oradata/orcl/undotbs01.dbf
/u01/app/oracle/oradata/orcl/sysaux01.dbf
/u01/app/oracle/oradata/orcl/users01.dbf
/u01/app/oracle/oradata/orcl/example01.dbf
/u01/app/oracle/oradata/orcl/BEIWAIONLINEV4.dbf

6 rows selected.

(2)SQL> select name from v$tempfile;

NAME
--------------------------------------------------------------------------------
/u01/app/oracle/oradata/orcl/temp01.dbf

(3)SQL> select name from v$controlfile;

NAME
--------------------------------------------------------------------------------
/u01/app/oracle/oradata/orcl/control01.ctl
/u01/app/oracle/oradata/orcl/control02.ctl
/u01/app/oracle/oradata/orcl/control03.ctl

(4)SQL> select member from v$logfile;

MEMBER
--------------------------------------------------------------------------------
/u01/app/oracle/oradata/orcl/redo03.log
/u01/app/oracle/oradata/orcl/redo02.log
/u01/app/oracle/oradata/orcl/redo01.log

四、關(guān)閉數(shù)據(jù)庫

shutdown immediate

五、拷貝第三步運行結(jié)果中的所有文件到你的新目錄中，這里假設(shè)新目錄是：/u02/oradata/
備注：這里所指的所有文件是第三步運行那幾個命令列出來的文件。

六、修改第二步生成的那個init<SID>.ora文件，在$oracle_home/dbs中。把在三步中用select name from v$controlfile;查出來的文件路徑都改為新的路徑。這里假設(shè)的路徑是/u02/oradata/$controlfile.

七、按照下面操作啟動數(shù)據(jù)庫
SQL>startup mount pfile=<file name>

命令：SQL>startup mount pfile=$oracle_home/dbs/init<SID>.ora(備注：就是第二步生成的那個文件名和文件路徑。)

八、更新文件系統(tǒng)
I:\DBFAS\DATA\SYSTEM01.DBF
I:\DBFAS\DATA\SYSAUX01.DBF
I:\DBFAS\DATA\UNDOTBS01.DBF
I:\DBFAS\DATA\USERS01.DBF
I:\DBFAS\DATA\INDX01.DBF

alter database rename file 'H:\DBFAS\DATA\SYSTEM01.DBF' to 'D:\DBFAS\DATA\SYSTEM01.DBF';
alter database rename file 'H:\DBFAS\DATA\SYSAUX01.DBF' to 'D:\DBFAS\DATA\SYSAUX01.DBF';
alter database rename file 'H:\DBFAS\DATA\UNDOTBS01.DBF' to 'D:\DBFAS\DATA\UNDOTBS01.DBF';
alter database rename file 'H:\DBFAS\DATA\USERS01.DBF' to 'D:\DBFAS\DATA\USERS01.DBF';
alter database rename file 'H:\DBFAS\DATA\INDX01.DBF' to 'D:\DBFAS\DATA\INDX01.DBF';
#SQL>alter database rename file 'I:\DBFAS\DATA\TEMP01.DBF' to 'D:\DBFAS\DATA\TEMP01.DBF';
#SQL>alter database rename file '/u01/app/oracle/oradata/orcl/temp01.dbf' to '/u02/oradata/temp01.dbf';
alter database rename file 'I:\DBFAS\LOG\REDO01.LOG' to 'D:\DBFAS\LOG\REDO01.LOG';
alter database rename file 'I:\DBFAS\LOG\REDO02.LOG' to 'D:\DBFAS\LOG\REDO02.LOG';
alter database rename file 'I:\DBFAS\LOG\REDO03.LOG' to 'D:\DBFAS\LOG\REDO03.LOG';
#SQL>alter database rename file '/u01/app/oracle/oradata/orcl/redo01.log' to '/u02/oradata/redo01.log';
#SQL>alter database rename file '/u01/app/oracle/oradata/orcl/redo02.log' to '/u02/oradata/redo02.log';
#SQL>alter database rename file '/u01/app/oracle/oradata/orcl/redo03.log' to '/u02/oradata/redo03.log';
備注：這里是更新第三步查詢出來的所有文件，但是select name from v$controlfile;查詢出來的文件不用命令更新。

九、查看文件是否更新成功

SQL> select name from v$datafile;
SQL> select name from v$tempfile;
SQL> select name from v$controlfile;
SQL> select member from v$logfile;

 select name from v$datafile;
 select name from v$tempfile;
select name from v$controlfile;
 select member from v$logfile;
運行結(jié)果所有指向了/u02/oradata/的話，證明更新成功

十、打開數(shù)據(jù)庫

SQL> alter database open;

十一、創(chuàng)建一個新的spfile，運行下面命令

SQL> create spfile from pfile;

注釋：如果不放心可以把原來路徑下的文件換到別的目錄，或者刪除。關(guān)閉數(shù)據(jù)庫后重新啟動一次數(shù)據(jù)庫查詢一下看看........
