没有更多的数据可以从套接字错误中读取

No more data to read from socket error(没有更多的数据可以从套接字错误中读取)

问题描述

我们使用 Oracle 作为 Web 应用程序的数据库.应用程序大部分时间运行良好，但我们收到没有更多数据可从套接字读取"错误.

We are using Oracle as the database for our Web application. The application runs well most of the time, but we get this "No more data to read from socket" error.

我们使用 spring、hibernate，我的应用程序上下文文件中有以下数据源.

We use spring, hibernate and i have the following for the datasource in my applciation context file.

<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>

我不确定这是因为应用程序错误、数据库错误还是网络错误.

I am not sure whether this is because of application errors, database errors or network errors.

我们在oracle日志中看到以下内容

We see the following on the oracle logs

甲骨文版本:11.2.0.1.0

推荐答案

对于此类错误，您应该求助于 oracle 支持.不幸的是，您没有提到您使用的是什么 oracle 版本.该错误可能与优化器绑定偷看有关.根据不同的 oracle 版本适用不同的解决方法.

For errors like this you should involve oracle support. Unfortunately you do not mention what oracle release you are using. The error can be related to optimizer bind peeking. Depending on the oracle version different workarounds apply.

您有两种方法可以解决这个问题:

You have two ways to address this:

• 升级到11.2
• 设置oracle参数_optim_peek_user_binds = false

当然下划线参数应该只在oracle支持建议的情况下设置

Of course underscore parameters should only be set if advised by oracle support
