标题：记录一次ORA-600 kccpb_sanity_check_2和ORA-600 kcbgtcr_13 错误恢复

晚上朋友告诉我数据库不能open,请求技术支持,检查alert日志发现ORA-00600[kccpb_sanity_check_2]错误导致数据库无法正常mount
Fri Jun 6 23:36:08 2014 alter database mount Fri Jun 6 23:36:08 2014 This instance was first to mount Fri Jun 6 23:36:12 2014 Errors in file /on3000/oracle/admin/on3000/udump/on30001_ora_295198.trc: ORA-00600:内部错误代码, 参数:[kccpb_sanity_check_2], [18045], [17928], [0x000000000], [], [], [], [] ORA-600 signalled during: alter database mount...
依次替换三个控制文件依然无法解决该问题。查询MOS得到解释为[435436.1]
ORA-600 [kccpb_sanity_check_2] indicates that the seq# of the last read block is higher than the seq# of the control file header block. This is indication of the lost write of the header block during commit of the previous cf transaction.
出现该故障的原因是因为写丢失导致,而解决该故障的方法有
1) restore a backup of a controlfile and recover OR 2) recreate the controlfile OR 3) restore the database from last good backup and recover
该数据库为无备份非归档数据库,因此只能重建控制文件来解决ORA-00600[kccpb_sanity_check_2]故障,通过重建控制文件数据库mount成功.但是在open的过程中又出现需要一个不存在的归档日志(数据库一个节点5月5日异常,另外一个节点5月23日异常,到6月6日我接手中间进行了N多操作,未细细分析原因).
Oracle Database Recovery Check Result检查结果
数据库SCN
控制文件中关于数据文件SCN
数据文件头SCN
REDO SCN
这里明显表示thread#缺少归档,导致恢复过程出现如下提示
最后没有办法只能使用_allow_resetlogs_corruption参数跳过redo,然后去open数据库,很不幸出现更加悲催的ORA-00704和ORA-00600[kcbgtcr_13]错误,导致数据库open失败

这里可以知道,数据库在读取obj$的时候使用到了undo cr块的构造,由于某种原因导致构造cr块失败,从而出现ORA-00600[kcbgtcr_13]错误,而因为obj$又在bootstarp$里面,因此又出现ORA-704.所以解决该问题的方法就是让数据库在查询obj$表的时候不再进行cr块构造,比如使用bbed提交事务等方法解决.这里使用bbed提交事务(bbed模拟提交事务一之修改itl),数据库启动成功
