使用Java连接到DB2 zOS数据库时出错

Question

连接到DB2 zOS服务器时出现以下错误。 有人可以帮忙吗？ 我们已经将Jar文件db2jcc4.jar与其他与JDBC相关的Jar文件一起使用了。 我还需要使用“ db2jcc_license_cu.jar”文件吗？ 我在解决这个问题上遇到了困难。

我们也尝试了db2jcc.jar，但是没有成功。

Java代码如下。

import java.io.PrintWriter;
import java.io.StringWriter;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class DB2Connection {

    public DB2Connection() {
        // TODO Auto-generated constructor stub
    }

    public static void main(String[] args) {

        String jdbcClassName="com.ibm.db2.jcc.DB2Driver";
        String url="jdbc:db2://ip-address:port/mydb";

        String user="user";
        String password="password";

        Connection connection = null;
        try {
            //Load class into memory
            Class.forName(jdbcClassName);
            System.out.println("**** Loaded the JDBC driver");
            //Establish connection
            connection = DriverManager.getConnection(url, user, password);

        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (SQLException e) {
            e.printStackTrace();
        }finally{
            if(connection!=null){
                System.out.println("Connected successfully.");
                try {
                    connection.close();
                } catch (SQLException e) {
                   // e.printStackTrace();
                    StringWriter errors = new StringWriter();
                    e.printStackTrace(new PrintWriter(errors));
                    System.out.println("Exception: " + errors.toString());
                }
            }
        }

    }

Answer 1

由于信誉不足，我无法添加评论，但听起来“ ABCP”可能不是正确的数据库名称。 在这里看看： http : //www-01.ibm.com/support/docview.wss?uid=swg21443723它列出了查找数据库名称的方法。 如果使用正确的名称，请再次检查端口。

至于许可问题。 在我的应用程序中，我同时使用db2jcc4.jar和db2jcc_license_ciuz.jar。我相信您需要_ciuz，jar才能访问DB2 z / OS，而不需要_cu.jar，但是通常许可证问题导致的错误与您显示的错误不同。
