非archive 模式下更改datafile/redolog位置

 數據庫建庫的時候指定數據文件多出來一個子目錄htdisdb

如今要作的操做是讓oracle 認出移動數據文件,

1)確認當前的模式,而且把關閉歸檔模式

 

SQL> archive log list;  查看歸檔模式是否打開
Database log mode              Archive Mode
Automatic archival             Enabled
Archive destination            /oradata/htdisdbarc2
Oldest online log sequence     37
Next log sequence to archive   39
Current log sequence           39

關閉歸檔模式

 

SQL> startup nomount;
ORACLE instance started.

Total System Global Area 1610612736 bytes
Fixed Size                  2084296 bytes
Variable Size             385876536 bytes
Database Buffers         1207959552 bytes
Redo Buffers               14692352 bytes
SQL> alter database mount;

Database altered.

SQL> alter database noarchivelog
  2  ;

Database altered.

SQL> alter database open;

Database altered.

2)查看數據文件位置

SQL> select name from v$datafile;

NAME
---------------------------------------------------
/oradata/htdisdb/htdisdb/system01.dbf
/oradata/htdisdb/htdisdb/undotbs01.dbf
/oradata/htdisdb/htdisdb/sysaux01.dbf
/oradata/htdisdb/htdisdb/users01.dbf

3)移動數據文件到目標文件夾

[oracle@htdtest htdisdb]$ mv *.dbf ../

4)重啓數據庫到mount狀態

 

SQL> startup nomount;
SQL> alter database mount;

5)重命名數據文件

 

SQL> alter database rename file '/oradata/htdisdb/htdisdb/sysaux01.dbf' to '/oradata/htdisdb/sysaux01.dbf';

Database altered.

SQL> alter database rename file '/oradata/htdisdb/htdisdb/undotbs01.dbf' to '/oradata/htdisdb/undotbs01.dbf';

Database altered.

SQL> alter database rename file '/oradata/htdisdb/htdisdb/users01.dbf' to '/oradata/htdisdb/users01.dbf';

Database altered.

SQL> alter database rename file '/oradata/htdisdb/htdisdb/temp01.dbf' to '/oradata/htdisdb/temp01.dbf';

Database altered.

SQL>

6)重命名重作日誌文件

alter database rename file '/oradata/htdisdb/htdisdb/redo01.log' to '/oradata/htdisdb/redo01.log';
alter database rename file '/oradata/htdisdb/htdisdb/redo02.log' to '/oradata/htdisdb/redo02.log';
alter database rename file '/oradata/htdisdb/htdisdb/redo03.log' to '/oradata/htdisdb/redo03.log';

7)更改數據庫到open狀態,從新查詢數據文件位置

 

SQL> alter database open;

Database altered.

SQL> select name from v$datafile;

NAME
--------------------------------------------------------------------------------
/oradata/htdisdb/system01.dbf
/oradata/htdisdb/undotbs01.dbf
/oradata/htdisdb/sysaux01.dbf
/oradata/htdisdb/users01.dbf
/oradata/htdisdb/isaccdb.dbf
/oradata/htdisdb/isposdb.dbf
/oradata/htdisdb/ismngdb.dbf
/oradata/htdisdb/isstldb.dbf
/oradata/htdisdb/istxndb.dbf
/oradata/htdisdb/isacqdb.dbf
