Java With Named Instance Of Sql Server
Feb 18, 2004
How to connect to the named instance of SQL Server using Java?
I had the following code working fine(but with the default instance only)
SET JAVA_HOME=D:Program FilesJavaSoftJRE1.3.1_03
"D:Program FilesJavaSoftJRE1.3.1_03injava" -classpath Launcher.jar;Sprinta2000.jar;log4j.jar;activation. jar;mail.jar Launcher -Ddatabase -Uuser -Ppassword -Sserver:1433 -hlocalhost -p9900 -TTrue -VFalse -QK -QS
But the same code is failing with the named instance:
SET JAVA_HOME=D:Program FilesJavaSoftJRE1.3.1_03
"D:Program FilesJavaSoftJRE1.3.1_03injava" -classpath Launcher.jar;Sprinta2000.jar;log4j.jar;activation. jar;mail.jar Launcher -Ddatabase -Uuser -Ppassword -Sserverinstance:1434 -hlocalhost -p9900 -TTrue -VFalse -QK -QS

I have a java compiled jar file, which accept the connection string as follows: -Uusername -Ppassword -Sservername:port
This string works fine with the default instance of SQL Server, I mean as long as you supply the name of the SQL Server as 'SQLServer', but if I want to run it against the named instance of SQL Server like 'SQLSERVERNamedInstance' then the connection is failing, giving me the unknown host error. Any idea why?

The box I am trying to connect to is running two instances of SQL Server.
There is a SQL Server 2005 instance which is the default. There is a SQL Server 2000 instance which is named 'SQLSERVER'.
I can connect to the SQL Server 2000 instance no problem:<add key="ConnectionString" value="server=MYPCSQLSERVER;database=mydatabase;user id=****;password=****" />
However, I am having trouble connecting to the Default SQL Server 2005 instance. I have tried:
<add key="ConnectionString" value="server=MYPC;database=mydatabase;user id=****;password=****" />
but it doesn't work. I have tried explicitly setting SQL Server 2005 to use port 1434 (as SQL Server 2000 is running on port 1433), and then used:
<add key="ConnectionString" value="server=MYPC,1434;database=mydatabase;user id=****;password=****" />
but this doesn't work either.
Am I mssing something here? Any help much appreciated
Thanks...

I've two instances(Default, Named[dynamicsFINANCE]) running on SQL server 2014. However, when I try to connect to named instance say (dynamicsFINANCE) using SQL authentication from local SSMS, I get below error message:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)
I assigned a static port number to the named instance [dynamicsFINANCE] 1450. I also setup the firewall rule to allow access to Port 1450.

I have a 3 node cluster on which I have installed SSAS as it's own insntance. I have created this as a named instance and can connect to it by serverinstance if I'm on the server itself. However from my desktop I get the error saying instance was not found on server name.
I have defined an alternate port and setup firewall rules and can connect via server:port but not serverinstance. Prior to making this change SSAS was running on default port of 2383 and I could connect just by servername.
I have read many articles for previous versions saying that clustered SSAS will always use 2383 and that you must connect just using servername. However and this is were it gets strange. I have a 2 node UAT cluster with SSAS setup exactly the same way I've described above and I can connect from my desktop as serverinstance.
Should I be able to connect as serverinstances for a named clustered instance in 2012 ?

Thanks for Microsoft's Windows XP Service Pack 2 and Windows Server 2003 that make the security much stronger. However, besides the invisible benefit so far, I have become the victim of this security policy.
I have several named instances of SQL 7/2000 installed in my machine. They are not visible out of the Microsoft new fire wall. I need to access the instances from outside the fire wall, but I don't know which port I should open for the instances.
From SQL online, the default instance of SQL server is connected through TCP/IP by default port 1433. I could successful open that port and made the default instance visible to outside. However, the port 1433 doesn't work for the named instances. SQL online said, the port for named instance is dynamically (by default) chosen the first time the instance is started. So, actually, I have no way to know the port.
Is there anyway that I can check the database or somewhere to get the port that is used by the named instance?
Thanks for any input and recommendation.

We have installed SQL 2000 SP4 on Windows 2000 Server. We created named instances on the SQL server.
When trying to connect to named instances from a remote sql client which is on windows 2000 and windows 2003, its throwing an error message saying that remote connections are disabled.
But, remote connections are enabled on the SQL server.
After changing the component services settings on windows 2003 where sql client is installed, we are able to connect to named instances.
But, after applying the same settings on another windows 2003 machine, we are unable to connect to the same instances.
We have another machine where we installed SQL 2005 on windows 2003 SP1. When trying to connect to named instances from any remote client, its throwing an error message saying that remote connections are disabled. But, remote connections are enabled in SQL server settings. We tried connecting to the instances by changing the component services settings but still we are facing the same issues.
Can you please help me on above issues?

Hi, I have a task in hand to migrate (upgrade) from SQL2K named instance to SQL2K5 default instance. There are many intranet applications touching current SQL2K. I would like to perform this upgrade such that I don't have to touch any application code - meaning I don't have to change the connectionstring to point to new Default instance. How can I achieve this?
So, in otherwords, here is what I want to achieve:
Current Server: SQL2K: SERVER_AINSTANCE_A (named instance)
Upgraded Server: SQL2K5: SERVERB (default instance)
If I have both default, I could achive this by setting up DNS alias after migration done so that any call for SERVER_A would point to SERVER_B. But in my case, I don't have SERVER_A, I have named instance. Is there any solution?
Regards,
Vipul

I am trying to perform a distributed query however have a situation I haven't dealt with before the linked server I add to do the query is a named instance (DVD_NASDOMINO). How would I specify this in a query as in the FROM part in a sql statement. I tried the obvious DVD_NASDOMINO.qlsdat.dbo.stmenqry and DVD_NAS.DOMINO.qlsdat.dbo.stmenqry.
Both returned errors in the query.
Thanks for the help.

I am trying to set up a Named Instance of SQL 2000 on the same machine that has a default instance of SQL 7.0. The setup always completes and I am able to register the Named Instance of the SQL Server with which it was installed on. However, when I try to connect the users to the database, with both windows and SQL authentication, I receive a SQL server not found error. I have tried an alias setup as well as physically specifying the port number in settup up an ODBC connection.
Has anyone ran into similar problems?
Also, has anyone been able to successfully complete the process as mentioned above?

I have a server with sql server 2005 installed as the default instance -- I have a piece of software that needs SQL2000 to be the default instance. Is there a way other than install new sql2005 named instance and move databases to rename my SQL2005 instance from <machinename> to <machinename>sql05 for example?

I have opened up a port on a remote SQL instance and can see that the port is LISTENING when using the PortQry tool. I have also set the TCP port in the TCP/IP properties in the IPAll section for that instance, yet I am unable to connect and get an error of
Connection Timeout Expired. The timeout period elapsed while attempting to consume the pre-login handshake acknowledgement. This could be because the pre-login handshake failed or the server was unable to respond back in time. The duration spent while attempting to connect to this server was - [Pre-Login] initialization=1; handshake=14998; (.Net SqlClient Data Provider)
I have done this on other instances, although they were default instances, and it has always worked fine.

We have 3x instances of SQL Server 2012 installed on a single remote server - there's the default MSSQLSERVER instance, then INSTANCE01 and INSTANCE02. I can remotely connect to the default MSSQLSERVER instance through SSMS, but I cannot connect to either of the additional named instances (INSTANCE01 or INSTANCE02).Â
For example, if I try to connect to "sql.domain.com", I can successfully access the default instance on the remote server. If I try to connect to "sql.domain.comINSTANCE01", I get an error stating
"A network-related or instance-specific error occurred while establishing a connection to SQL Server".
However - if I try to connect to "sql.domain.comINSTANCE01, 49301" (where 49301 is the TCP Port for the TCP/IP Protocol for this SQL Server instance), I am able to successfully connect.
This leads me to think that there's a communication issue with the SQL Server Browser service running on the remote SQL Server and my workstation.Â
The following items have been verified:
SQL Server Browser is running on the remote SQL ServerWindows Firewall has been disabled on the SQL ServerTCP Ports 1433, 1434, 1954, and 49301 have been opened up on the remote destination's firewallUDP Port 1434 has been opened up on the remote destination's firewall.

I have TWO named SQL Server instances (on the same machine) and I need to know the port of each of them, how can I do that? Is it write to check the following:
Which one to take: "TCP Dynamic Ports" or "TCP Port"? and what is the difference between them anyways?Â
Can the two instances (or more)Â on the same machine use the same port?!

Several applications in out environment use Microsoft access to access the SQL server databases. Our new SQL Server 2005 instance is a named instance. We would like to create a .reg file to update the individual workstations as part of the migration. For some reason the .reg file with a named instance does not work. If the entry is created through the GUI it works. The server drop down does not show the named instance, only the server name but if you type the servernameamed_instance it finds it ok. Here is an example of what works and what does not. Any ideas on what the problem might be?

I have two instances of SQL Server on the same PC:
Default instance: SQL Server 2000
Named instance with name €œMS2005€?: SQL Server 2005.
Also I have another SQL Server 2005 on another PC.
I created a .NET 2.0 Compact Framework application that connects to the database and executes simple query. This application can connect to any instance of the SQL Server when it is executed on the PC (not on the server). But the problem is that when I try to execute the application from the windows CE 5.0 device, the application can only connect to the default instance (SQL 2000 and 2005) and can not connect to the named instance (Name: MS2005).
Is it some kind of limitation of the SqlClient library for the compact framework?
Below are the code and connection strings:
string connectionString = €œServer=1.1.1.1;Database=DB1;Uid=sa;Pwd=€?
string connectionString = €œServer=1.1.1.1\MS2005;Database=DB1;Uid=sa;Pwd=€?
using (SqlConnection connection = new SqlConnection(connectionString))
{
connection.Open(); //This is the point where exception is generated
using (SqlCommand command = connection.CreateCommand())
{
command.CommandText = "select count(*) from users";
object result = command.ExecuteScalar();
Console.WriteLine("Result: [{0}]", result);
}
connection.Close();
}
Thank you for your time and advice.

Good Day,
I am creating a SQL Named instance as a testing environment. This instance is on the same physical box as my Development environment, both are SQL 2005 standard edition. From the server in Management Studio, I can load, and interact with both instances. From a remote connection (e.g., my pc) I cannot access the named instance. I am getting the following:
Connect to Server
X Cannot connect to <server><named instance>
Additional Information
An error has occured while establishing a connection to the server. When connecting to SQL Sever 2006, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)(Microsoft SQL Server)
I have checked, and rechecked the server settings for this named instance, and remote connections are set to "allow" I have enabled TCPIP and Named Pipes prototocals, and have ensured that my firewall is allowing the "listenting port" for the named instance, and have even tried turning off my XP firewall during testing.
I am sure that I have probably missed something, and have searched the community but only have been able to find resolutions that I have already tried. Is there more?
Thanks in advance for any help and guidance you can provide.

We are trying to quickly put together what needs to be accomplished to install a named instance of SQL Server 2000 on an existing production server (also running SQL Server 2000). It appears as if the install will require a reboot. Can the reboot be postponed until after-hours without impacting the default instance of SQL Server?
Also, I see that if certain services are stopped prior to installing sp4 that you can avoid a reboot. However, if we are unable to stop these services (DTC, for example) without impacting the default instance of SQL Server, will the default instance of SQL Server experience any issues if we postpone the post-sp4 reboot until after hours?
Thanks!
Michelle

I have SQL Server 2000 Standard Edition (sp3a) running on a windows 2003 (sp4) Server.
It is a Production Server with 3 NAMED Instances and NO Default Instance.
Does anyone know if I can rerun the SQL Server Install and add a DEFAULT Instance to this box without disrupting the other Named Instances???

I installed SQL Server 2005 recently on a cluster. I didn't go for the default instance and instead I named the instance option. Now I would like to migrate everything from the named instance to the default instance, which I haven't yet installed.
Is this an easy process? What about the logins and the maintenance plans and jobs? Is there anything else I need to be aware of?

Hi
I've never had to do this, but when I downloaded the Web Workflow Approvals Starter Kit, it requested that I install the database into a User Instance of .SQLEXPRESS.
Now the problem is, I've installed it onto a default instance, so I was wondering whether you can create a named instance on top of a default instance... and if so, how would you do that?
Cheers
Chris

In QA we have a two-node cluster with four instances of sql. In trying to add a fifth, I was given an IP address already in use so the install hung.
I removed it from the cluster but it is still there in the registry etc on the node I was working on.
I read about using the maintenance tab of the sql server install to "remove a node" but the terminology is confusing. To me a node is a physical server and an instance is an instance of sql server -- not the same at all but they are often referred to as the same thing.
I definitely don't want to remove one of the servers from the cluster.

I have an existing 2012 default SQL Express. It's set up on a VPS managed by a third party. I have an administrator account on this 2012 Windows server. I'm not much of a sysadmin or a DBA but I get around. ;)
I've installed a new NAMED instance on this VPS and can not connect to it with client tools (SSMS). If I remote in, I can connect this way.
What steps might a seasoned DBA expect to make when getting a new named instance ready for the world.
Assign a port? Check the port?
Open the firewall for the port?
Will this new named instance listen on a different port than the previously installed SQL Express instance?

I try to connect from a pc to a SQL Server on another pc. Both pc’s are in a workgroup. I want to connect from a Windows Forms application to a named instance on the other computer. By now I have been able to connect from one pc to SQL Server on the other with tcp:smurfin, 52782.
I want to be able to use servernameinstancename (instead of portnumber) to make a connection in a Windows Forms application.
I’ve checked / tried te following:
•In the properties of the instance, tab Connections, the option Allow Remote Connections is enabled
•In Configuration Manager: TCP is enabled
•The service SQL Server Browser is started
•On the tab IPAddresses, in the section IPAll, there is NO portnumber for TCP Port. And TCP Dynamic Ports has the nummer 52782
•I have created un inbound rule for port 52782 and also for 1434 (SQL Server Browser). And to be on the save side: a rule for 1433 as well.
•Restarted the service
If I run the following code in SQL Server, that same port number (52782) is returned:
EXEC xp_ReadErrorLog 0, 1, N'Server is listening on', N'any', NULL, NULL, 'DESC'
GO
SELECT local_tcp_port
FROM sys.dm_exec_connections
WHERE session_id = @@SPID
[Code] ....

started my named instance in single user mode and restored master. sqlserve.exe -c -m -s ovops
now the instance won't start. tried starting it with the -t3608 switch.. won't start!!
Its because my drive configuration is different on the new server than it was on the old server, I cannot start the instance because it is expecting model, msdb, temdb and all of the user databases on drives that don't exist?? what can I do?????

Here's my situation:I have an ODBC DSN setup for Timberline Data (An accounting packagethat uses pervasive.sql) on my sql box. I set up a linked server usingthe supplied timberline odbc driver. I have two sql instances setup,the default instance and a named instance. On the default instance,the linked server works great no matter who is logged in using it (allauthentication is NT integrated). However on the named instance onlythe NT account that the MSSqlserver$NAMED service is logged in undercan utilize the linked server. All others get a ODBC error:"error 7399: OLE DB Provider 'MSDASQL' reported an error. AccessDenied. OLE DB error trace [OLE/DB Provider 'MSDASQL'IUnknown::QueryInterface returned 0x80070005: Access Denied.]."Far as i can tell, both instances are setup the same, except that oneis the default and one is a named instance.Why the different results for the default instance vs a named instance.Any ideas?Thanks

We have two instances of SQL Server 2005 - SP1 installed on one server. The default instance starts very slowly. When looking at the log I can see the delay is due to Resource Manager based upon the following error.
Message
Resource Manager Creation Failed: 0x8004d102
(XACT_E_DUPLICATE_GUID)
What does this mean?
What would cause this to happen?
How do I resolve the problem?
