步驟：

備份數據庫

backup database

1、use rman backup database?

rman target /?

rman>backup as compressed backupset format 'f:\backup\full_%d_U' database;?

遷移用戶存放的數據文件

1、tablespace offline?

sql>alter tablespace USERS offline normal;?

sql>alter tablespace BSCHIS_DATA offline normal;?

sql>alter tablespace MPI offline normal;?

sql>alter tablespace BSHIS offline normal;?

sql>alter tablespace PHIS offline normal;?

sql>alter tablespace BSLIS offline normal;?

sql>alter tablespace PFLIS offline normal;?

sql>alter tablespace PHIS23 offline normal;?

sql>alter tablespace HISTEST offline normal;?

sql>alter tablespace LIS offline normal;?

2、CP datafile to new destination?

3、alter tablespace rename datafile?

sql>alter tablespace USERS rename datafile 'N:\ORADATA\ORCL\USERS01.DBF' to 'E:\oradata\USERS01.DBF' ;?

sql>alter tablespace BSCHIS_DATA rename datafile 'N:\ORADATA\ORCL\BSCHIS_DATA.DBF' to 'E:\oradata\BSCHIS_DATA.DBF' ;?

sql>alter tablespace MPI rename datafile 'N:\ORADATA\ORCL\MPI.DBF' to 'E:\oradata\MPI.DBF' ;?

sql>alter tablespace BSHIS rename datafile 'N:\ORADATA\ORCL\BSHIS.DBF' to 'E:\oradata\BSHIS.DBF' ;?

sql>alter tablespace PHIS rename datafile 'N:\ORADATA\ORCL\PHIS.DBF' to 'E:\oradata\PHIS.DBF' ;?

sql>alter tablespace BSLIS rename datafile 'N:\ORADATA\ORCL\BSLIS.DBF' to 'E:\oradata\BSLIS.DBF' ;?

sql>alter tablespace PFLIS rename datafile 'N:\ORADATA\ORCL\PFLIS.DBF' to 'E:\oradata\PFLIS.DBF' ;?

sql>alter tablespace PHIS23 rename datafile 'N:\ORADATA\ORCL\PHIS23.DBF' to 'E:\oradata\PHIS23.DBF' ;?

sql>alter tablespace HISTEST rename datafile 'N:\ORADATA\ORCL\HISTEST.DBF' to 'E:\oradata\HISTEST.DBF';?

sql>alter tablespace LIS rename datafile 'N:\ORADATA\ORCL\LIS.DBF' to 'E:\oradata\LIS.DBF' ;?

4、alter tablespace online?

sql>alter tablespace USERS online;?

sql>alter tablespace BSCHIS_DATA online;?

sql>alter tablespace MPI online;?

sql>alter tablespace BSHIS online;?

sql>alter tablespace PHIS online;?

sql>alter tablespace BSLIS online;?

sql>alter tablespace PFLIS online;?

sql>alter tablespace PHIS23 online;?

sql>alter tablespace HISTEST online;?

sql>alter tablespace LIS online;

遷移數據庫redolog 文件

1、add loggroup

sql>alter database add logfile group 4('E:\oradata\redo04.log') size 50M;?

sql>alter database add logfile member 'E:\oradata\redo004.log' to group 4;?

sql>alter database add logfile group 5('E:\oradata\redo05.log') size 50M;?

sql>alter database add logfile member 'E:\oradata\redo005.log' to group 5;?

sql>alter database add logfile group 6('E:\oradata\redo06.log') size 50M;?

sql>alter database add logfile member 'E:\oradata\redo006.log' to group 6;?

2、drop old loggroup file

sql>alter database drop logfile group 1;

sql>alter database drop logfile group 2;

sql>alter database drop logfile group 3;

3、sql>alter system switch logfile;

注意刪除舊的loggroup 需要確定 loggroup 為inactive 狀態。

select status ,group# from v$log 確定。

遷移temp tablespace 臨時表空間文件 ??

1、create a new temp tablespace?

sql>create temporary tablespace temp02 tempfile 'e:\oradata\temp02.dbf' size 512M autoextend on next 500m MAXSIZE UNLIMITED;?

2、set default temp tablespace?

sql>alter database default temporary tablespace temp02;?

3、drop old temp tablespace?

sql>drop tablespace temp including contents and datafiles;

數據庫undotablespace 文件

sql> CREATE UNDO TABLESPACE UNDOTBS2 DATAFILE 'e:\oradata\undotbs02.dbf' SIZE 5120M AUTOEXTEND ON NEXT 10M MAXSIZE UNLIMITED ONLINE RETENTION NOGUARANTEE BLOCKSIZE 8K FLASHBACK ON;?

sql>alter system set undo_tablespace ='UNDOTBS2';?

sql>ALTER SYSTEM SWITCH LOGFILE;?

sql>drop tablespace undotbs1 including contents;

??

遷移數據庫的control 文件

change control file location?

1、sql>create pfile from spfile?

2、shutdown database?

sql>shutdown immediate?

3、edit pfile change location?

cp old control file to new destination?

4、startup database?

sql>startup pfile='xxx.ora';?

5、create new spfile?

sql>create spfile from pfile='xxx.ora'?

6、shutdown database?

sql>shutdown immediate?

7、startup database?

sql>startup?

備份數據庫

backup database

1、use rman backup database?

rman target /?

rman>backup as compressed backupset format 'f:\backup\20140729full2221_%d_U' database;?

結束

在原來數據文件目錄（N:\oradata\orcl\） 下有system.dbf 和sysaux.dbf 文件，為數據庫本身系統文件 是數據庫存放數據字典的文件，不建議改動，未做遷移。
