我們正在使用Oracle作為Web應(yīng)用程序的數(shù)據(jù)庫。該應(yīng)用程序在大多數(shù)情況下都運(yùn)行良好，但是出現(xiàn)了“不再需要從套接字讀取數(shù)據(jù)”錯誤。Caused by: java.sql.SQLRecoverableException: No more data to read from socket    at oracle.jdbc.driver.T4CMAREngine.unmarshalUB1(T4CMAREngine.java:1142)    at oracle.jdbc.driver.T4CMAREngine.unmarshalSB1(T4CMAREngine.java:1099)    at oracle.jdbc.driver.T4CTTIfun.receive(T4CTTIfun.java:288)    at oracle.jdbc.driver.T4CTTIfun.doRPC(T4CTTIfun.java:191)    at oracle.jdbc.driver.T4C8Oall.doOALL(T4C8Oall.java:523)    at oracle.jdbc.driver.T4CPreparedStatement.doOall8(T4CPreparedStatement.java:207)    at oracle.jdbc.driver.T4CPreparedStatement.executeForDescribe(T4CPreparedStatement.java:863)    at oracle.jdbc.driver.OracleStatement.executeMaybeDescribe(OracleStatement.java:1153)    ... 63 more我們使用spring，hibernate，并且在我的應(yīng)用程序上下文文件中有以下數(shù)據(jù)源。<bean class="org.apache.commons.dbcp.BasicDataSource"        destroy-method="close" id="dataSource">        <property name="driverClassName" value="${database.driverClassName}" />        <property name="url" value="${database.url}" />        <property name="username" value="${database.username}" />        <property name="password" value="${database.password}" />        <property name="defaultAutoCommit" value="false" />        <property name="initialSize" value="10" />        <property name="maxActive" value="30" />        <property name="validationQuery" value="select 1 from dual" />        <property name="testOnBorrow" value="true" />        <property name="testOnReturn" value="true" />        <property name="poolPreparedStatements" value="true" />        <property name="removeAbandoned" value="true" />        <property name="logAbandoned" value="true" />    </bean>我不確定這是由于應(yīng)用程序錯誤，數(shù)據(jù)庫錯誤還是網(wǎng)絡(luò)錯誤引起的。Oracle版本：11.2.0.1.0
