low cache rba:(0x26.ed5.0) on disk rba:(0x26.109a.0)
on disk scn: 0x0000.0028e440 07/06/2013 13:11:33

原因是读取thread 2的redo logfile发现其仅写到4248个块， 但实际control中记录ON DISK DBA该为109a 即4250。

尝试重建控制文件：

SQL> alter database backup controlfile to trace;

Database altered.



SQL> alter system set cluster_database=false scope=spfile;

System altered.

SQL> startup force nomount;

重建控制文件后问题消失， 主要问题还是 主机断电对redo logfile的写丢失， 而控制文件却更新了on disk rba，导致控制文件中的RBA大于redo logfile中实际存在的， 通过重建控制文件后2者一致 从而问题消失。
