（原創(chuàng)）ORA-01092: ORACLE 例程終止。強行斷開連接

供稿：網友
今天測試部門的人叫我過去，說是數據庫當了，起不來了。
我過去看了看情況，做了如下操作
SQL> shutdown immediate數據庫已經關閉。已經卸載數據庫。Oracle 例程已經關閉。SQL> startupORACLE 例程已經啟動。

表面上看不出問題，我查看alert_oracas.log文件

于是我查看了以下信息來確認undo表空間的問題

SQL> startup mountORACLE 例程已經啟動。

當時沒有自己看問題，就以為是undo文件損壞了，決定重建。
注重：后來才發(fā)現這里以后的操作是饒了一個解決問題的彎路。
由于不open沒有辦法重新創(chuàng)建undo 表空間，所以決定先用系統(tǒng)默認的undo表空間來啟動，然后重建undo
表空間，具體操作如下：
SQL> create pfile from spfile;
文件已創(chuàng)建。
修改pfile文件
#*.undo_management='AUTO'#*.undo_tablespace='UNDOSTB1'undo_management=manualundo_tablespace='system'
關閉數據庫，并且從目錄F:/oracle/ora92/database下去掉SPFILEORACAS.ORA文件
重新啟動
SQL> shutdown immediateORA-01109: 數據庫未打開
已經卸載數據庫。ORACLE 例程已經關閉。SQL> startup mountORACLE 例程已經啟動。

查看表空間信息

NAME------------------------------CWMLITEDRSYSEXAMPLEINDXODMSYSTEMTOOLSUNDOTBS1USERSXDBTEMPTSCAS1TSCAS2TSCAS3TSCAS4TSCASINDX1TSCASINDX2SNAPSHOT_TS
并且打開圖形界面查看，這時候才發(fā)現undo表空間的名字是UNDOTBS1
其實早就能發(fā)現的，大家以后分析問題一定不要太快下結論，要自己分析。。。
于是做以下操作改變undo 表空間的名字
SQL> create spfile from pfile;
文件已創(chuàng)建。
SQL> shutdown immediate數據庫已經關閉。已經卸載數據庫。ORACLE 例程已經關閉。SQL> startupORACLE 例程已經啟動。

系統(tǒng)已更改。
SQL> alter system set undo_tablespace='undotbs1' scope=spfile;
重啟驗證：
SQL> shutdown immediate數據庫已經關閉。已經卸載數據庫。ORACLE 例程已經關閉。SQL> startupORACLE 例程已經啟動。

發(fā)現已經好使了
教訓總結：其實只要一開始分析下v$tablespace就能發(fā)現是undo表空間的名字錯了，很快就能解決的。
不過我上面這種方法可以用于undo表空間文件corrupt的情況：）
