《DBA入门、进阶与诊断案例》中2.3.1章节的案例进行模拟

我修改了pfile中的undo_tablespace='UNDOTBS2'参数值，重新以加载pfile文件的方式启动数据库。

查看alter_<sid_name>.log中的记录发现如下报错：

启动数据库都mount状态

1 2 3 4 5 6 7 8

SQL> startup mount pfile='/DBBK/oracle/product/11.2.0.1.0/dbs/initorcl.ora'; ORACLE instance started.

查看启动参数，发现数据库mount的是UNDOTBS2

1 2 3 4 5 6 7 8

SQL> show parameter undo_tablespace NAME                                 TYPE                              VALUE ------------------------------------ --------------------------------- ------------------------------ undo_tablespace                      string                            UNDOTBS2 SQL> show parameter pfile NAME                                 TYPE                              VALUE ------------------------------------ --------------------------------- ------------------------------ spfile                               string

那么这里可以确定，因为我启动的时候没有使用SPFILE，或者另一种情况SPFILE中的参数值被我不小心改错了。导致启动时候加载错误而参数的报错。
