问题描述

我试图连接到安装在远程系统上的ms sql server2008.但是它显示错误.以下是我尝试过的方法

I was trying to connect to ms sql server 2008 which is installed on a remote system.But it showing error.The following is the way i had tried

import java.io.File;
import java.sql.Connection;  
import java.sql.DriverManager;  
import java.sql.PreparedStatement;
import java.sql.ResultSet;  
import java.sql.Statement;  


public class mssql {  
    public static void main(String[] args) {  
        try {  
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();

            Connection connection=DriverManager.getConnection("jdbc:sqlserver://192.168.1.220:1433;databaseName=sales;integratedSecurity=true;");
            if(!(connection==null))
            {
                System.out.println("connected");
            }

//            


        } catch (Exception e) {  
            e.printStackTrace();  
        }  
    }  
}  

这是我遇到的错误

com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host 192.168.1.220, port 1433 has failed. Error: "connect timed out. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.".

任何解决此问题的方法

推荐答案

是否已将2008 SQL实例配置为用于TCP连接的listening?

Is the 2008 SQL instance configured to be listening for TCP connections?

开始，Microsoft SQL Server 2008，配置工具，SQL Server配置管理器 SQL Server网络配置
[实例名称]
的协议 应该列出四个项目:

Start, Microsoft SQL Server 2008, Configuration Tools, SQL Server Configuration Manager SQL Server Network Configuration
Protocols for [instance name]
There should be four items listed:

• 共享内存
• 命名管道
• TCP/IP
• VIA

对于您的环境，应该启用和禁用哪些?大多数设置都要求启用共享内存"和"TCP/IP"，而其他设置则被禁用.

For your environment, which should be enabled and which should be disabled? Most setups call for Shared Memory and TCP/IP enabled, the others disabled.
