通过alert和trace中的内容可以知道，数据库需要恢复到rba到13350，但是因为某种原因实例恢复的时候，只能利用1 thread 99189 seq#，恢复rba到13350。从而导致数据库无法正常open 
This Problem is caused by Storage Problem of the Database Files. 
The Subsystem (eg. SAN) crashed while the Database was open. 
The Database then crashed since the Database Files were not accessible anymore. 
This caused a lost Write into the Online RedoLogs and so Instance Recovery is not possible and raising the ORA 

4.解决方法 

Sql代码 





在这次恢复中，主要就是重建控制文件，然后直接恢复成功，如果redo有损坏，那么可能需要使用不完全恢复，然后使用resetlogs打开数据库
