----------------------------------------------------------------------------------

原因分析：

select data error.No more data to read from socket Caused exception message is: No more data to read from socket 原因分析：Oracle 11g數據庫優化器(optimizer_features_enable)的版本是11.2.0.1。使用該版本的優化器會造成執行過長的SQL語句報錯,終止應用的運行

----------------------------------------------------------------------------------

解決方案一：

重啓數據庫 此辦法可以迅速解決問題（臨時）

解決方案二：

修改Oracle 11g數據庫的優化器的版本爲10.2.0.4，修改方法如下（無需重啓數據庫即可生效） SQL>alter system set optimizer_features_enable='10.2.0.4';
