ORA-600(kghfrf1)错误

客户的10.2.0.4 FOR AIX数据库在刷新物化视图时碰到这个错误。
错误信息为:

Fri Oct  5 06:20:27 2012
Errors IN file /home/oracle/app/admin/orcl/udump/orcl_ora_4272180.trc:
ORA-00600: internal error code, arguments: [kghfrf1], [0x000000000], [], [], [], [], [], []

从TRACE文件可以看到,出现错误时在执行的语句是物化视图的刷新:

*** 2012-10-05 06:20:27.599

ORA-00600: internal error code, arguments: [kghfrf1], [0x000000000], [], [], [], [], [], []

根据MOS文档ORA-600 [Kghfrf1] On Execution of MV_JOB_PROC Job [ID 816733.1],这个问题是在物化视图刷新时清理内存引发的错误。确认影响的版本为10.2.0.4和9.2.0.7,该问题在11.1.0.6和10.2.0.5中进行了FIXED。
由于该问题并非每次刷新都会引发,加上物化视图刷新的JOB有自动重试的功能,因此该问题在不频繁出现的情况下,也可以采取忽略的策略。
