Default Versus Named Instance With Custom App

Aug 2, 2007

Are there some general recommendations/guidelines/best practices for choosing to run your custom application against a default or named instance of SQL Server?

We have an application, which in it's stand-alone/local configuration, installs an MSDE default instance if it does not already exist, and runs against this instance. In addition, regardless of whether or not it installs the default instance, it expects to run against the default instance.

We are looking into migrating to SQL Server 2005 Express (Compact almost fits our needs, but not quite), and would like to pay more attention to the best solution regarding the use of instances, default versus named.

Thanks

Migrating From SQL2K Named Instance To SQL2K5 Default Instance

Feb 19, 2007

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

Named Instance Problems (Default Of 7.0/2000 Instance)

Oct 10, 2001

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?

Move SQL2005 From Default Instance To Named Instance

Mar 2, 2007

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?

Migrating From Named Instance To Default Instance

Oct 30, 2007

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?

Create A Named Instance On Top Of A Default Instance

Apr 13, 2007

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

Connection String For Default Instance Of SQL Server 2005, On A Box Also Running A Named Instance Of SQL Server 2000

Nov 15, 2007

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...

Should ISVs Install Named Or Default Instance With Their Software?

May 31, 2006

For ISVs who distribute/install SQL Server Express with their software, what is the best practice when it comes to choosing between installing a default or a named instance?

From what I can tell, I should install a named instance, so that the named instance can be uninstalled when my software is uninstalled without hosing other named instances or the default instance, but I'm not 100% sure of this.

Adding A Custom Named Instance To Windows Firewall Exception List

Aug 14, 2007

We install SQL Express 2005 with a custom named instance. Since a named instance uses dynamic ports, how can I add this named instance to the Windows Firewall exception list? Previously with MSDE 2000 we installed as default, then I added port 1433 to the Firewall exception list.

Is there a way to install SQL Express to a static port (programmatically)? Or, is there a better method, like adding the SQL custom named instance service to the firewall exception list?

Named Pipes Versus TCP/IP Sockets

Sep 25, 1998

We are having some problems using TCP/IP connection and was wondering what the benefits are to using this versus Named Pipes. The company that provides our software stated that this would improve performance but I do not see it and I am getting a lot of errors connecting. This also locks many of the users and I end up having to stop and start the database to clear the locks because there are so many. Would it be better to place the clients on Multi-protocol. It seems more powerful to use but I wanted to get some feedback from some people that may have dealt with this issue before.

Thanks,

SQL Server Admin 2014 :: Cannot Connect To Named Instance (2nd Instance) From Local SSMS

Jul 22, 2015

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.

SQL 2012 :: Clustered SSAS Unable To Connect To Named Instance (instance Not Found On Server)

Mar 20, 2014

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 ?

Named Instance

Sep 4, 2003

I am running SQL2k SP3 with a default instance. I have recently added a second, named instance. When I try to connect to the named instance through Enterprise manager, it often times out. I never get a timeout accessing the default instance. Is there something I missed when setting up the second instance that is causing this access delay?

Thanks,

Removing Named Instance

Jan 9, 2007

We want to rename our instance and I understand there isn't a straightforward way to do so. I'm prepared to run SQLEXPR again to create the new named instance. However, I'm not clear on how to remove the other named instance once the data files have been moved over. I do not want the old service "SQL Server (<old_named_instance>)" to be running. I would also like the files "C:Program FilesMicrosoft SQL ServerMSSQL.1" removed along with the registry entries for this instance.

I tried running SQLEXPR with a /? option but that invoked the installer and did not give me the command line options. Is there a simple way to remove a specific named instance? Thanks.

Named Instance Problem

Oct 25, 2007

Hi everybody,

Here is my problem: I'm setting up a new computer with SQL 2005 to replace the old one with SQL 2000. What I want to do is to transfer all the data from the SQL Server 2000 to the 2005 then rename the 2005 from the temp name to the same name as the SQL 2000, so all the pages can connect to the 2005 instead of the 2000. The problem right now is that all of the pages that that are being published within the network is calling the SQL 2000 by it instance only eg: Data Source = MainSQLServer. With the SQL 2005 I can't just call the instance in the connection string, it requires that the computer's name and the instance be provided, eg: \computer_nameinstance_name. I can't go back and edit every single one of the pages being served. So I need to configure the SQL 2005 in a way that all of the existing pages can access it with the same connection string that is in use right now to connect to the SQL 2000.

Thanks for the help!

Creating A New Named Instance

Sep 7, 2007

As understand it, the only way to add another SQL Express 2005 named instance is to run SQLEXPR32.EXE again. However, when you to, right at the end, you get the following error message:

"An installation package for the product MS SQLK Server VSS Writer cannot be found. Try the installation again using a valid copy of the installation package 'SQLWriter.msi'"

So, I deleted all named instances, and the repeated the procedure and did not get this error and it installed fine. Obviously, I would not be able to delete all instances, but in this case it didn't matter.

So, here are my questions:

Question 1) Am I correct you must rerun SQLEXPR32.EXE to create a new named instance? (I think the answer is yes)

Question 2) Is there a way to rename an existing named instance? (I think the answer is no)

Question 3) The install/uninstall for SQLEXPR32.EXE is incredibly buggy. I have spend days trying to remove an named instance with no succes. Once your remove all named instances from Control Pannel, you stll have not removed SQL Express 2005. How do you remove it? We are considering other avenues because of the incredible problems with this product. Also, we inadvertantly installed SQL Express 2005 Advanced Services, when we meant to install SQL Express 2005, so we would like to uninstall Advance Serviuces and reinstall SQL Express 2005

Question 4) I am switching from the Outlook Express newsgroups to these groups. In the context of these groups, what is the difference betwee a Forum and a Newsgroup?

Thanks

I cannot find anything online or in BOL about the proper format for a named instance in the routing address.

is it simply

Clustering && Named Instance

Dec 7, 2007

Hi all,

I have some questions regarding Clustering.

(1) Can we create Default Instance & Named Instance in the clustering environment (i.e.) two instances in clustering on same hardware.

The idea here is , to put some highly transactional databases on default instance ( and giving 5 CPU's to Default instance ) and on the Named Instance ( giving 3 CPU's for Named Instance) in CLUSTERING ENVIRONMENT.

(2) Can anyone guide me , how can we restrict the instances to take 5 Cpu's & 3 Cpu's repectively Iin CLUSTERING ENVIRONMENT.

Thanks.

Default Vs Named Instances

Feb 25, 2007

I have a server computer named 'X' and I would like to install 2 instances of SQL Server 2005

1. SQLTEST

2. SQLDEV

During installation. if I select Default instance then it will name my sql server instance X . I don't want that. I want to have essentially 2 named instances to make it clear to the users that they are using a test and dev sql server. Whats the best way to do this? I am open to suggestions if there is a different way to do this.

Is it required to have a default instance? Can I have 2 named instances XSQLDEV and XSQLTEST?

Also, on the SQLTEST I will be installing reporting services. By not having a default instance will it cause issues for the SSRS installation.

Please help!

Thanks.

How Can I Get The Port Of A Named Instance Of SQL Server

Sep 14, 2004

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.
