有朋友反馈数据库启动运行一点时间之后,然后就自动crash,让我们帮忙找原因,通过分析是由于smon进程触发ORA-600 13013导致数据库异常

通过trace文件大概可以发现是由于ORA-600 13013错误导致数据库crash,而且这里有类似”SMON was doing flushing of monitored table stats”错误提示,根据经验,很可能是smon把表的dml操作收集信息相关.

ORA-600 [13013] 含义

ORA-600 [13013] [a] [b] {c} [d] [e] [f] 


This format relates to Oracle Server 8.0.3 to 10.1 

Arg [a] Passcount 
Arg [b] Data Object number 
Arg {c} Tablespace Relative DBA of block containing the row to be updated 
Arg [d] Row Slot number 
Arg [e] Relative DBA of block being updated (should be same as 1) 
Arg [f] Code 

根据这个错误信息,以及How to resolve ORA-00600 [13013], [5001] [ID 816784.1]中的描述

ORA-600 13013 对应对象

SQL> select object_name from dba_objects where object_id=482

OBJECT_NAME
--------------------------------------------------------------------------------
MON_MODS$

该对象正是和监控dml变化相关的表,smon会对其进行相关操作,以前写过一篇:MON_MODS$和MON_MODS_ALL$统计DML操作次数的文章
对于MON_MODS$表ORA-600 13013处理

SQL> analyze table mon_mods$ validate structure cascade;

analyze table mon_mods$ validate structure cascade
*
ERROR at line 1:
ORA-01499: table/index cross reference failure - see trace file

 
SQL> select index_name from dba_indexes where table_name='MON_MODS$';

INDEX_NAME
------------------------------
I_MON_MODS$_OBJ

SQL> ALTER INDEX I_MON_MODS$_OBJ REBUILD;

Index altered.

SQL> analyze table mon_mods$ validate structure cascade;
analyze table mon_mods$ validate structure cascade
*
ERROR at line 1:
ORA-01499: table/index cross reference failure - see trace file

SQL> CREATE TABLE MON_MODS_BAK AS SELECT * FROM MON_MODS$;

Table created.

SQL> SELECT COUNT(*) FROM MON_MODS$;

  COUNT(*)
----------
      1247

SQL> C/MON_MODS$/MON_MODS_BAK;
  1* SELECT COUNT(*) FROM MON_MODS_BAK
SQL> /

  COUNT(*)
----------
      1247

SQL> TRUNCATE TABLE MON_MODS$;

Table truncated.

SQL> INSERT INTO MON_MODS$ SELECT * fROM MON_MODS_BAK;

1247 rows created.

SQL> COMMIT;

Commit complete.

SQL>  analyze table mon_mods$ validate structure cascade;

Table analyzed.

自此关于MON_MODS$表相关的ORA-600 13013异常处理完全,当然也可以通过重建I_MON_MODS$_OBJ索引来解决,但是不能通过rebuild index解决.数据库也就不会因此而crash了.
