Question

我是java oracle数据库编码的新手，我在运行下面的代码时遇到此错误（eclipse kepler）：

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class main {

    public static void main(String[] args) {
        try {
            Class.forName("oracle.jdbc.OracleDriver");
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
            return;
        }
        Connection connection = null;
        try {
            connection = DriverManager.getConnection(
                    "jdbc:oracle:thin:@10.0.32.166:1521:orcl", "username", "password");
        } catch (SQLException e) {
            e.printStackTrace();
            return;
        }
    }
}

错误是针对ojdbc14.jar：

java.sql.SQLException: Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor

虽然我尝试更改ojdbc6.jar但出现了不同的错误：

java.sql.SQLException: Listener refused the connection with the following error:

我在2 jar上进行实验的原因是我不确定哪个与jdk 1.6兼容，因为这是我将在完成后部署（linux env）可执行jar。需要帮助来确定这些错误是什么以及解决它们的想法？谢谢

Answer 1

你没有数据库＆＃34;叫＆＃34; orcl在数据库服务器10.0.32.166上，并在端口1521上运行oracle侦听器。

从服务器10.0.32.166上的控制台执行lsnrctl status，看看您是否有像Service "ORCL" has X instance(s).这样的行。如果您没有这样做，请确保数据库已启动并且您具有正确的SID，它正在端口1521上使用侦听器。

ORA-12505，TNS：监听器目前不知道SID
