准备工作 下面的信息说明了如果是完全恢复，可以看到insert into test1 values(16);，否则可以看到15，就是被归档的那个。17因为没有提交，是不会被恢复的。

重建控制文件（这种丢失的状态重建控制文件是错误的）

可见，因为缺少所有的redo，重建控制文件是行不通的。
Mount数据库

用using backup controlfile进行恢复

用Open Resetlog 打开数据库

alter database open

SQL> alter database open RESETLOGS;

验证恢复结果：不完全恢复，redo里面的数据丢失了
SQL> conn lunar/lunar
SQL> select * from test1 where a>10;
SQL> conn internal
SQL> archive log list;

说明：
1. 把热备的数据文件和控制文件拷贝过来
2. mount数据库
3. 根据提示重建口令文件
4. 用using backup controlfile进行恢复
5. 用Open Resetlog 打开数据库
