故障出现描述：

前几天搭建了一套 二节点单实例 的 linux+oracle11.2.0.3+dataguard   maximize availability   的环境。

今天在主节点上把dataguard环境铲掉，操作步骤是：

1.创建pfile文件 sql>create pfile=‘/opt/oracle/initorcl.ora‘   from  spfile;

2.编辑initorcl.ora文件，将与dataguard相关的配置删除

3.从新的pfile文件initorcl.ora启动数据库SQL> startup pfile=‘/opt/oracle/initorcl.ora‘

这时候报错ora-03113：

 SQL> startup pfile=‘/opt/oracle/initorcl.ora‘
ORACLE instance started.

查看trace日志 有ora-16072错误

解决办法是：

1. statup正常启动数据库

2. 更改数据库保护模式成“最大性能”    SQL> alter database set standby to maximize; performance;

3. 从新的pfile启动数据库SQL> startup pfile=‘/opt/oracle/initorcl.ora‘

4. 创建spfile文件SQL> create spfile from  pfile=‘/opt/oracle/initorcl.ora‘;

    

故障原因：猜测应该是数据库在“最大可用”maximize availability   模式下，却找不到相关的“保护配置参数”
