ORA-00600 [kddummy_blkchk]错误一例-白红宇

一套HP-UX Itanium平台上的10.2.0.2，实例意外终止，维护人员尝试重启实例，在数据库打开后数秒，smon后台进程报ORA-00600: internal error code, arguments: [kddummy_blkchk], [120], [856039], [6110]错误，实例再次意外终止。部分告警日志如下:

当Oracle进程在读取数据块时会做一系列逻辑检测，当发现块当中存在逻辑讹误就会触发该ORA-00600 [kddummy_blkchk]等内部错误；[kddummy_blkchk]内部函数的功能大致与[kdBlkCheckError]相仿，它们都有3个参数argument： ORA-600 [kddummy_blkchk] [file#] [block#] [check code] ORA-600 [kdBlkCheckError]
