SQL关闭连接-需要增加超时吗?

我在我的 Java 连接到my时的应用程序 Oracle 数据库

我是否需要增加超时或对XML配置进行任何其他更改?

下面是我的 persistence .xml文件:

 <persistence-unit name="mypersistenceUnit">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <class>com.my.package.entities.Person</class>
        <class>com.my.package.entities.Address</class>

        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>
            <property name="hibernate.connection.provider_class" value="org.hibernate.c3p0.internal.C3P0ConnectionProvider"/>

        </properties>
    </persistence-unit>
