（原创）ORA-01092: ORACLE 例程终止。强行断开连接

今天测试部门的人叫我过去，说是数据库当了，起不来了。

我过去看了看情况，做了如下操作

SQL> shutdown immediate数据库已经关闭。已经卸载数据库。ORACLE 例程已经关闭。SQL> startupORACLE 例程已经启动。

Total System Global Area  135338868 bytesFixed Size                   453492 bytesVariable Size             109051904 bytesDatabase Buffers           25165824 bytesRedo Buffers                 667648 bytes数据库装载完毕。ORA-01092: ORACLE 例程终止。强行断开连接

表面上看不出问题，我查看alert_oracas.log文件

于是我查看了以下信息来确认undo表空间的问题

已选择30行。

已选择18行。当时没有自己看问题，就以为是undo文件损坏了，决定重建。

注意：后来才发现这里以后的操作是饶了一个解决问题的弯路。

由于不open没有办法重新创建undo 表空间，所以决定先用系统默认的undo表空间来启动，然后重建undo

表空间，具体操作如下：

SQL> create pfile from spfile;

文件已创建。

修改pfile文件

#*.undo_management=@#AUTO@##*.undo_tablespace=@#UNDOSTB1@#undo_management=manualundo_tablespace=@#system@#

关闭数据库，并且从目录F:\oracle\ora92\database下去掉SPFILEORACAS.ORA文件

重新启动

SQL> shutdown immediateORA-01109: 数据库未打开

已经卸载数据库。ORACLE 例程已经关闭。SQL> startup mountORACLE 例程已经启动。

Total System Global Area  135338868 bytesFixed Size                   453492 bytesVariable Size             109051904 bytesDatabase Buffers           25165824 bytesRedo Buffers                 667648 bytes数据库装载完毕。SQL> alter database open;

查看表空间信息

SQL> show parameter undo

NAME------------------------------CWMLITEDRSYSEXAMPLEINDXODMSYSTEMTOOLSUNDOTBS1USERSXDBTEMPTSCAS1TSCAS2TSCAS3TSCAS4TSCASINDX1TSCASINDX2SNAPSHOT_TS

并且打开图形界面查看，这时候才发现undo表空间的名字是UNDOTBS1

其实早就能发现的，大家以后分析问题一定不要太快下结论，要自己分析。。。



于是做以下操作改变undo 表空间的名字

SQL> create spfile from pfile;

文件已创建。

SQL> shutdown immediate数据库已经关闭。已经卸载数据库。ORACLE 例程已经关闭。SQL> startupORACLE 例程已经启动。

Total System Global Area  135338868 bytesFixed Size                   453492 bytesVariable Size             109051904 bytesDatabase Buffers           25165824 bytesRedo Buffers                 667648 bytes数据库装载完毕。数据库已经打开。SQL> show parameter undo

SQL> alter system set undo_management=auto scope=spfile;

系统已更改。

SQL> alter system set undo_tablespace=@#undotbs1@# scope=spfile;

重启验证：

SQL> shutdown immediate数据库已经关闭。已经卸载数据库。ORACLE 例程已经关闭。SQL> startupORACLE 例程已经启动。

Total System Global Area  135338868 bytesFixed Size                   453492 bytesVariable Size             109051904 bytesDatabase Buffers           25165824 bytesRedo Buffers                 667648 bytes数据库装载完毕。数据库已经打开。SQL> create fpile from spfile;create fpile from spfile       *ERROR 位于第 1 行:ORA-00901: 无效 CREATE 命令

发现已经好使了

教训总结：其实只要一开始分析下v$tablespace就能发现是undo表空间的名字错了，很快就能解决的。

不过我上面这种方法可以用于undo表空间文件corrupt的情况：）
