我在某个地方读到，池中的大多数连接都处于非活动状态，但在我的情况下，大多数连接都处于活动状态。我不知道为什么会这样，或者问题就在于此

我还将oracle参数设置为

但到目前为止，一切都无济于事。任何帮助都将不胜感激。谢谢

localhost:SID不工作，我改为localhost:portnumber:servicename，现在可以工作了。非常感谢：-）-sneha

请发布代码/服务方法，问题发生在servlet的doGet方法中。项目是简单的动态web项目。执行以下语句时引发异常：java.sql.Connection con=DriverManager.getConnection（“jdbc:oracle:thin:@localhost:：，“username”，“password”）；请您发布加载驱动程序等的代码。@sneha是

Class.forName（“oracle.jdbc.driver.OracleDriver”）调用getConnection方法之前调用？
