無解的錯誤訊息ORA-7445 [OPIXGUID()+13]?
我們的Oracle資料庫時有Core Dump, 錯誤訊息為ORA-7445 [OPIXGUID()+13],一直找不到真正的原因為何?有意思的是,在官方支援網站My Oracle Support上找相關文件,看到一篇文件Troubleshooting ORA-7445 [opixguid] [ID 1469649.1],它的內容:
Information in this document applies to any platform.
簡單地說,客戶提了很多ORA-7445的錯誤,大部份他們以不是錯誤結案,或者是無法再現該錯誤,或因資訊不足而擱置。
這種錯誤,就是偶而出現,大部份時候都可以正常的跑SQL,也許10天,也許半個月,也許很久才會出現一次Core Dump, 是很難找的問題。也就是其再現性是隨機的,無規律的。目前看來,連官方也還沒找到真正的問題。
