检查告警日志文件信息如下：

问题比较明显，日志镜像存在问题，由于测试库可以通过resetlog方式打开：
SQL> alter system set "_allow_resetlogs_corruption"=true scope=spfile;

System altered.
SQL> startup mount
ORACLE instance started.

Total System Global Area 1653518336 bytes
Fixed Size 2228904 bytes
Variable Size 1140854104 bytes

Redo Buffers 7118848 bytes
Database mounted.

SQL> recover database until cancel;
Media recovery complete.
SQL> alter database open resetlogs;

Database altered.
此时告警日志信息如下：
Fri Aug 24 09:53:56 2012
alter database open resetlogs
ORA-1139 signalled during: alter database open resetlogs...
Fri Aug 24 09:54:27 2012
