甲方在做灾备切换演练的时候，有一套数据库不能正常启动，基本的报错都是：ORA-30012: undo tablespace 'UNDOTBS1' does not exist or of wrong type 。下面记录一下其解决过程。

可以看到UNDO表空间的名称和从控制文件中查到的名称不一致，下面修改SPFILE文件中有关UNDO表空间的部分，如下所示：
| SYS@oraLHR1> ALTER SYSTEM SET undo_tablespace='UNDO1' SID='oraLHR1';
System altered.
SYS@oraLHR1> ALTER SYSTEM SET undo_tablespace='UNDO2' SID='oraLHR2';
System altered.

4 故障处理总结
ORA-30012基本是由于参数文件中的undo_tablespace的值和控制文件中记录的值不一致导致的。可以使用ALTER SYSTEM修改或者直接修改参数文件中有关undo_tablespace的部分和控制文件中的一致即可。
关于为何会出现参数文件和控制文件中undo_tablespace的值不一致的情况，这个可以从告警日志中去查询，这里就不深究了，毕竟是个测试库，也许很多年都没人使用了吧。
