Oracle數據庫教程：ORA-01103錯誤解析

這是一測試庫，我將參數文件，控制文件，數據文件全部刪除之后，做數據恢復，但是

我把控制文件和參數文件都恢復回來了，可數據庫卻怎么也打不開，報ORA-01103: database name 'WWL' in control file is not 'DUMMY'錯誤
-
 

我的數據庫名稱是:WWL

2、執行過程：

恢復參數文件：

RMAN> setDBID=5520179

executing command: SET DBID

RMAN> restorespfile from autobackup;

Starting restore at 23-MAY-12

using target database control file insteadof recovery catalog

allocated channel: ORA_DISK_1

channel ORA_DISK_1: sid=39 devtype=DISK

channel ORA_DISK_1: looking for autobackupon day: 20120523

channel ORA_DISK_1: autobackup found:c-5520179-20120523-04

channel ORA_DISK_1: SPFILE restore fromautobackup complete

Finished restore at 23-MAY-12

RMAN>

3、恢復控制文件

RMAN> restorecontrolfile from autobackup;

Starting restore at 23-MAY-12

using channel ORA_DISK_1

channel ORA_DISK_1: looking for autobackupon day: 20120523

channel ORA_DISK_1: autobackup found:c-5520179-20120523-04

channel ORA_DISK_1: control file restorefrom autobackup complete

output filename=/DBSoft/product/10.2.0/db_1/dbs/cntrlWWL.dbf

Finished restore at 23-MAY-12

RMAN>

4、報錯信息：

RMAN> sql 'alterdatabase mount';

sql statement: alter database mount

SQL> alterdatabase mount;

alter database mount

ERROR at line 1:

ORA-01103: database name 'WWL' in controlfile is not 'DUMMY'

注意：問題是我恢復的控制文件沒有錯呀，在本機器上也沒有部署過DUMMY的數據庫呀，只有一個實例是WWL。

查詢實例信息，實例信息顯示沒有錯呀是WWL。

SQL> selectinstance_name,status from v$instance;

INSTANCE_NAME    STATUS

---------------- ------------

WWL              STARTED

SQL> alterdatabase mount;       ----順便執行了下mount database;

alter database mount

*

ERROR at line 1:

ORA-01103: database name 'WWL' in controlfile is not 'DUMMY'

奇怪的事發生了，現在再次登錄到RMAM居然連接到的是DUMMY庫：

問題是，我確定沒有這個庫呀，怎么辦。。。

[Oracle@wwldb dbs]$rman target /

connected to target database: DUMMY (notmounted)

RMAN> exit     

我們剛才做了參數文件和控制文件的恢復，要不將數據庫重啟下，看有沒有問題。

SQL> shutdownimmediate

ORA-01507: database not mounted

Oracle instance shut down.

SQL> startupmount;

再次登錄正常。

[Oracle@wwldb dbs]$rman target /

這個問題我一兄弟在AIX，Linux，Windows 上分別做實驗了，結果是在Windows下不用重啟數據庫，Rman就可以認到，而不會是DUMMY數據庫。
B，每小時執行一次，整點執行

interval => 'trunc(sysdate,'HH')+1/24'

C，一個小時后執行

interval => 'sysdate+1/24'
