今天測試部門的人叫我過去，說是數(shù)據(jù)庫當(dāng)了，起不來了。
我過去看了看情況，做了如下操作
SQL
> shutdown immediate
數(shù)據(jù)庫已經(jīng)關(guān)閉。
已經(jīng)卸載數(shù)據(jù)庫。
Oracle 例程已經(jīng)關(guān)閉。
SQL

ORACLE 例程已經(jīng)啟動(dòng)。

當(dāng)時(shí)沒有自己看問題，就以為是undo文件損壞了，決定重建。
注意：后來才發(fā)現(xiàn)這里以后的操作是饒了一個(gè)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(rèn)的undo表空間來啟動(dòng)，然后重建undo
中國網(wǎng)管聯(lián)盟
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=manual
undo_tablespace=’system’
關(guān)閉數(shù)據(jù)庫，并且從目錄F:＼oracle＼oraArray2＼database下去掉SPFILEORACAS.ORA文件
重新啟動(dòng)
SQL
> shutdown immediate
ORA-0110Array: 數(shù)據(jù)庫未打開
已經(jīng)卸載數(shù)據(jù)庫。
ORACLE 例程已經(jīng)關(guān)閉。

并且打開圖形界面查看，這時(shí)候才發(fā)現(xiàn)undo表空間的名字是UNDOTBS1
其實(shí)早就能發(fā)現(xiàn)的，大家以后分析問題一定不要太快下結(jié)論，要自己分析。。。
于是做以下操作改變undo 表空間的名字
SQL

發(fā)現(xiàn)已經(jīng)好使了
教訓(xùn)總結(jié)：其實(shí)只要一開始分析下v$tablespace就能發(fā)現(xiàn)是undo表空間的名字錯(cuò)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：）
