ORA-12505, TNS: 侦听器当前不知道 SID

Question

我是 java oracle 数据库编码的新手，在运行以下代码 (eclipse kepler) 时出现此错误：

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 上进行试验的原因是我不确定哪个与 jdk 1.6 兼容，因为我将在完成后部署（linux env）可执行 jar。需要帮助确定这些错误是什么以及解决这些错误的想法吗？谢谢

Answer 1

您在数据库服务器 10.0.32.166 上没有“称为”orcl 的数据库，并且在端口 1521 上运行了 oracle 侦听器。

从服务器 10.0.32.166 上的控制台执行 lsnrctl status 并查看是否有类似 Service "ORCL" has X instance(s). 的行如果没有，请确保数据库已启动并且您拥有正确的 SID 并且它正在使用监听 1521 端口。
