在一次数据库的异常处理完成后,发现alert日志中出现ORA-600[13013]错误
Thu Mar 08 23:29:37 2012 Errors in file /opt/oracle/diag/rdbms/chf/chf/trace/chf_smon_24137.trc (incident=38681): ORA-00600: internal error code, arguments: [13013], [5001], [518], [4198427], [170], [4198427], [17], [], [], [], [], [] Incident details in: /opt/oracle/diag/rdbms/chf/chf/incident/incdir_38681/chf_smon_24137_i38681.trc Use ADRCI or Support Workbench to package the incident. See Note 411.1 at My Oracle Support for error and packaging details. Non-fatal internal error happenned while SMON was doing flushing of monitored table stats. SMON encountered 1 out of maximum 100 non-fatal internal errors.
trace文件中信息
从这里可以看出是对sys.col_usage$表进行update操作导致该错误发生

这次出现此问题的原因是因为在更新语句中使用索引找到一条记录,然后到表中去查询时该记录不存在,出现此错误,一般解决方法是重建索引

HANK,
看到了知道了
怎么知道4198427是BLOCK地址呢
补充一个类此的错误案例ORA-600 [13011]
