Sql Server Jdbc Error: The Tcp/Ip Connective To The Host Failed

I had installed SQL SERVER 2014 Express edition in addition to I was trying to connect to SQL SERVER from Java programme using JDBC, but I was repeatedly getting next error:

com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connexion to the host localhost, port 1433 has failed. Error: "connect timed out. Verify the connexion properties. Make certain that an event of SQL Server is running on the host in addition to accepting TCP/IP connections at the port. Make certain that TCP connections to the port are non blocked yesteryear a firewall.".Error piece closing connexion !!null

I had checked that event of Microsoft SQL SERVER was already running, every bit I was able to connect to it using SQL SERVER Management Studio (SSMS client). I had besides checked the JDBC URL, it's right in addition to also, JDBC driver is including inward CLASSPATH. So what was wrong? Why I was getting this error? in addition to finally, how I managed to cook this error? Read on ....

Cause of mistake TCP/IP connexion to the host Failed

If you lot are getting this mistake later on installing SQL SERVER 2012 or 2014 piece outset fourth dimension trying to connect from Java programme using JDBC, in addition to then it's most probable that your SQL SERVER is non withal configured to psyche for TCP/IP connexion on port 1433.

If you lot cause got already configured your MSSQL server to psyche on TCP/IP traffic on port 1433 then it could last whatever of next 3 reasons:

• Firewall is blocking the incoming connection
• SQL SERVER is non running on the host
• The port you lot cause got configured is non correct, i.e. its non 1433

If the SQL SERVER limited is non running in addition to then simply start your SQL Server, you lot tin practice thence yesteryear going into Windows Services tab or you tin besides start SQL Server from "SQL Server Configuration Manager", every bit shown below:

By default, when you lot install Microsoft SQL server inward Windows 8.1, it register itself every bit Windows service in addition to automatically starts when you lot log into Windows. Btw, if you lot are novel into JDBC basis in addition to non done much happen Java application interfacing database, in addition to then you lot should banking concern agree out Core Java, Volume II--Advanced Features, tenth Edition yesteryear Cay S. Horstmann, i of the best books to acquire advanced Java concepts.

TCP/IP connexion to the host Failed: Solution

The solution is to ensure that your SQL Server event is listening on the port. Follow these steps to ensure that SQL SERVER 2014 is start listening on port 1433:

1. Go to Start->All Programs-> Microsoft SQL Server 2012-> Configuration Tool
2. Click SQL Server Configuration Manager
3. Expand SQL Server Network Configuration-> Protocol
4. Enable TCP/IP Right box
5. Double Click on TCP/IP in addition to acquire to IP Addresses Tap in addition to Put port 1433 nether TCP port.

In Windows 8.1, you lot tin besides press Windows + c in addition to click on Search ikon to start searching for SQL Server Configuration Manager. Once works life simply click on it to open.

Anyway, in i lawsuit you lot got to the higher upward covert simply double click on highlighted TCP/IP link in addition to this volition opened upward the next window, brand certain you lot locomote into TCP Port every bit 1433. That's it.

That's all nearly how to cook The TCP/IP connexion to the host localhost, port 1433 has failed error piece connecting to SQL SERVER from Java using JDBC API. You besides require to create user in addition to logins inward companionship to connect using JDBC in addition to type iv JDBC driver. I am going to postal service that information presently inward adjacent brace of articles.
