看來今天運氣不錯,偶又見BUG.
正在和同事悠閒地吹牛,突然收到以上這個條這個資訊,下意識反映,su - oracle ;ps -ef | grep ora_.
hehe,一切還好,該在的都在.
根據alert.log資訊去看了一下trace.如下

在trace中看到一條SQL,難道是這條SQL造成的? 不像呀,這麼簡單的一條SQL.於是想看下Cause和oracle給出的Action資訊

oracle@hpdb:/home/oracle #oerr ora 07445
07445, 00000, "exception encountered: core dump [%s] [%s] [%s] [%s] [%s] [%s]"
// *Cause: An OS exception occurred which should result in the creation of a
//         core file.  This is an internal error.
// *Action: Contact your customer support representative.

差點眼鏡跌下來,oracle就是牛比,將錯誤推薦到OS上去了,看下OS日誌,沒有任何錯誤.

會不會是oracle的BUG呀?

到metalink上一看,哈哈,果然是中獎了.(Note:421203.1,Note:468274.1),哎,啥也不說了,繼續用吧,只要不當機就Thanks Goodness!
