ORA-12505，TNS：偵聽器當前不知道SID

Question

我是java oracle數據庫編碼的新手，運行以下代碼（eclipse kepler）時遇到此錯誤：

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;
        }
    }
}

錯誤適用於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

當我嘗試更改ojdbc6.jar時，出現了另一個錯誤：

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

我在2 jar上進行實驗的原因是我不確定與jdk 1.6兼容，因為這是我一旦完成將部署（linux env）可執行jar的原因。 需要幫助來確定這些錯誤是什么以及如何糾正這些錯誤？ 謝謝

您在數據庫服務器10.0.32.166上沒有在端口1521上運行oracle偵聽器的數據庫“ orcl”。

從服務器10.0.32.166上的控制台執行lsnrctl status ，並查看是否有像Service "ORCL" has X instance(s).這樣的行Service "ORCL" has X instance(s). 如果沒有，請確保數據庫已啟動並且您具有正確的SID，並且它正在使用端口1521上的偵聽器。
