版本不當導致的exp出錯

在一次exp匯出操作時遇到了ORA-00904,ORA-01003錯誤，多方搜尋也幾無所得。

匯出的大概情形如下：

D:\>exp user/pass@connstr file=d:\xx.dmp

伺服器和客戶端兩邊連線都很正常，百思不得解，難道是匯出版本的問題？不至於啊，1024匯出1023的庫，之前操作過，沒發現過這個問題，而且看提示不像啊，眾所周知版本錯誤會提示ORA-06550。實在無法，最後報著死馬當活馬醫的想法嘗試換了一個同版本的客戶端執行exp，結果順利執行。

後來又經過多番嘗試，發現出錯的均是含lob欄位的表，看來一方面oracle在執行exp時對版本的處理非常嚴格，即使大版本相同，小版本有略微差異也會導致exp時報錯，另一方面是處理規則也存在版本延續的情況，如果不涉及到處理規則的變化，即使exp時客戶端版本與伺服器不符，匯出時也有可能不報錯(運氣好的話)。

將此次事件記錄下來以加強記憶，以後執行匯出還是都儘可能確保版本一致吧(起碼exp的客戶端版本不能高於伺服器)。
