在做Oracle数据库巡检时发现数据库的alert日志中出现很多的如下报错:

ORA-07445这个是与ORA-00600其名的错误,MOS上特别为ORA-600、ORA-7445、ORA-700设置了检索入口,参见MOS 153788.1,但这次的7445错误没能在这个入口找到。该错误为oracle 10.2版本在HP Itanium平台的BUG,BUG号bug:5382798,,原因是由于在使用HP Itanium平台的C编译器编译oracle 10.2代码时出现异常,具体说明请参考MOS 386727.1。oracle已经为该BUG发布了patch,如果出现上述错误,建议安装对应的patch,也可以将数据库升级到10.2.0.3或以上版本。
