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());
}
}
}
}

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，请仔细检查端口。
关于许可问题。 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来访问DB2 z / OS而不是_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。
