DB2 数据库连接不上

[wcl_friend]

我有两台主机，其中一个只装了DB2数据库，做服务器用的，现在我把数据全导进去，发现数据库连不上了，老是给我报超时。
com.ibm.db2.jcc.a.DisconnectException: java.net.ConnectException : Error opening socket to server /10.145.42.110 on port 50000 with message : Connection timed out: connect DB2ConnectionCorrelator: null

后来我写了一个类测试下，还是不行，请高手指点下，谢了。

package dbConnection;

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

public class Test {
	public String url = "jdbc:db2://10.145.42.110:50000/DMS";
	public String driver = "com.ibm.db2.jcc.DB2Driver";
	public String userName = "db2admin";
	public String password = "db2admin";
	Connection conn = null;
	public Test() {
		try {
			Class.forName(driver);
			conn = DriverManager.getConnection(url, userName, password);
			System.out.println("success");
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
	public static void main(String[] args) {
		new Test();
	}
}

能telnet到10.145.42.110 的 50000端口么?试一下.

好像连不上啊，可为什么连不上呢？

It's almost impossible to tell what's wrong without the full error
message or sqlcode. Check the database server's error logs and the
administration server's logs for additional information. I believe that
you've encountered error SQL30020N - you can look it up in the online
information center.

连不上是数据库没启动.或者配置的原因.请确认数据库启动了!
