官方描述
The assert ORA-600: [kcrfr_update_nab_2] is a direct result of a lost write in the current on line log that we are attempting to resolve.So, this confirms the theory that this is a OS/hardware lost write issue not an internal oracle bug. In fact the assert ORA-600: [kcrfr_update_nab_2] is how we detect a lost log write.

Hdr: 6655116 10.2.0.3 RDBMS 10.2.0.3 RECOVERY PRODID-5 PORTID-23
Abstract: INSTANCES CRASH WITH ORA-600 [KCRFR_UPDATE_NAB_2] AFTER DISK FAILURE
根据官方的描述,结合故障情况,基本上可以确定是由于硬件异常导致Oracle写丢失,从而除非oracle相关bug导致数据库无法正常启动
ORA-600 [kcrfr_update_nab_2] [a] [b] VERSIONS: versions 10.2 to 11.1 DESCRIPTION: Failure of upgrade of recovery node (RN) enqueue to SSX mode ARGUMENTS: Arg [a] State Object for redo nab enqueue for resilvering Arg [b] Redo nab enqueue mode FUNCTIONALITY: Kernel Cache Redo File Read IMPACT: INSTANCE FAILURE
处理方法
1.如果有备份,利用备份进行不完全恢复,跳过最后异常的redo,数据库resetlogs打开
2.如果没有备份,尝试使用历史的控制文件进行不完全恢复,或者直接跳过数据库一致性打开库.
3.互联网有人解决删除redo第二组成员数据库open成功(http://blog.itpub.net/16976507/viewspace-1266952/)
