这个数据库重启是由于smon进程异常导致数据库关闭,然后rac自动拉起数据库,从而出现了循环重启启动,smon异常的主要原因是由于“ORACLE Instance orcl1 (pid = 13) – Error 607 encountered while recovering transaction (9, 33) on object 775794.”这个表示有实物要回滚,但是遇到了ORA-600 kddummy_blkchk异常,无法完成回滚从而使得smon进程异常进而使得数据实例crash.对于这个问题处理相对比较简单
1. 通过ORA-600 kddummy_blkchk找出来报错对象
ORA-00600: internal error code, arguments: [kddummy_blkchk], [a], [b], 1 ARGUMENTS: Arg [a] Absolute file number Arg [b] Block number Arg 1 Internal error code returned from kcbchk() which indicates the problem encountered.
2. 屏蔽实物回滚,打开数据库,然后对通过dba_extents 查询出来的对象/或者根据事务报错的object信息查询出来对象进行重建,完成本次恢复任务
关于ORA-00600: internal error code, arguments: [kddummy_blkchk], [a], [b], 相关目前已知bug
