找到了portaldb1_ora_40698472.trc （大约1.9G） 和portaldb1_ora_40698472_i642694.trc（11M左右） 两个文件 ；

其中portaldb1_ora_40698472_i642694.trc文件中的这个语句是不是造成这个报错的原因呢？已经把trc文件 和这个表给开发那边了，让开发那边也看看，

我还摸不着头绪，把故障现象发到这里，希望大家帮我看看，谢谢

odm finding :


  Format: ORA-600 [6749] [a]

VERSIONS:           
  versions 7.3 to 8.1

DESCRIPTION:        

  This internal occurs during the row change for update or delete.
  Some reported problems are consistent read issue, some bugs are related to  
  row corruption on the block.

FUNCTIONALITY:      
  ROW DELETE

IMPACT:            
  PROCESS FAILURE
  ROW CORRUPTION


[6749], [3], [37923665], [163], [], [], [], [], [], [], [], []


3 代表 row no longer exists 行不再存在
37923665 代表dba
C 是 行的slot number

由于11.2.0.3 上似乎没有对应的Bug,考虑对该表做ANALYZE TABLE <table_name> VALIDATE STRUCTURE CASCADE; 并flush buffer_cache； 如果错误仍存在，考虑重建该表
