今天在做数据库例检时，alert.log文件中出现如下错误：

Thu Jun 9 09:00:27 2011
Errors in file /u01/app/oracle/admin/xxxx/bdump/xxxx2_m001_577740.trc:
ORA-00600: internal error code, arguments: [kcbz_check_objd_typ_3], [0], [0], [1], [], [], [], []

查了一下，有如下BUG：

看起来是做ADDM时出现的错误，那么，是哪个Segment呢？

SQL> select object_id, data_object_id, owner, object_name, object_type from dba_objects

问题重现

先解决掉问题

SQL> alter system flush buffer_cache;

System altered.

SQL> select /*+ full(t) */ count(*) from WRH$_ACTIVE_SESSION_HISTORY t;

COUNT(*)
----------
106493

注意的是，RAC需要对每个节点都进行alter system flush buffer_cache;

问题解决了，但导致这个问题的原因还是未知，估计也是个BUG。这个Oracle的版本是10.2.0.1
