ORA-00600[6711]错误一例

一套Linux上的10.2.0.4系统，日志中频繁出现ORA-00600[6711]内部错误:

, [4256248], [1], [4256242], [0], [], [], []
Wed Sep  1 21:24:31 2010
Non-fatal internal error happenned while SMON was doing logging scn->]SQL> set linesize 200;
SQL> select segment_name, segment_type
2    from dba_extents
3   where relative_fno = 1
4     and (61938 between block_id and block_id + blocks or
5         61944 between block_id and block_id + blocks);

SEGMENT_NAME                                                                      SEGMENT_TYPE

SMON_SCN_TO_TIME                                                                  CLUSTER

不出意料是一个cluster，SMON_SCN_TO_TIME是SMON_SCN_TIME表的基簇，SMON_SCN_TIME表用以记录数据库中scn对应的时间戳。我们直接查看用以创建数据字典的sql.bsq文件，可以进一步了解他们的结构:

SQL> alter index smon_scn_to_time_idx rebuild ;

Index altered.

/* 在索引出现讹误的情况下仅仅rebuild往往是无效的，在我们rebuild的同时告警日志中再次出现了ORA-00600[6711]错误 !!! */

/* 我们需要的彻底把有问题的索引drop掉，并再次创建!!! */

SQL> drop index smon_scn_to_time_idx ;

Index dropped.

SQL> create index smon_scn_to_time_idx on cluster smon_scn_to_time;

Index created.

/* 至此问题解决，告警日志中不再出现错误! * /

/* That's great! * /
