数据库server出现ORA-00600[kcratr_nab_less_than_odr]。不能open数据库
1.open数据库报ORA-00600[kcratr_nab_less_than_odr]
SQL> ALTER DATABASE OPEN;
ALTER DATABASE OPEN

第 1 行出现错误:

通过alert和trace中的内容能够知道，数据库须要恢复到rba到43569，可是由于某种原因实例恢复的时候，仅仅能利用1 thread 99189 seq#，恢复rba到43531。
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-600.

--继续尝试恢复

SQL> ALTER DATABASE OPEN;
--open成功
在这次恢复中，主要就是重建控制文件，然后直接恢复成功。假设redo有损坏，那么可能须要使用不全然恢复。然后使用resetlogs打开数据库
