Single Instance/Multiple Instance/Virtualization Q
I work for a mid size company with the usual collection of enterprise applications. We are trying to consolidate our SQL environment consisting of around 100 databases none of which are over 100GB with the average database size around 5GB. Recently a large server was purchased as the "Big Daddy" SQL box. Obviously not all the databases will be moved to this one box but within reason a number can.
My question: What is the best way to configure the box?
1 OS & 1 Default Instance - How do we isolate loops memory leaks etc...
1 OS & Multiple instances, ie:Dedicated instance for each application. - How do you allocate CPU & memory, allow for optimum performance without putting others at risk from a rouge process?
Virtualized OS for each application with a default instance - Too much overhead impacts performance?
Future plans include offsite replication, perhaps mirroring with failover.
I'd appreciate anyone else's thoughts ideas? How have you tackled this problem in your environment?
Thanks

How To Move A Single Database From SQL Server Instance To New SQL Instance
Hi, I want to move one database from the source SQL Server 2000 instance to a new SQL 2000 instance in another machine. I have five user databases in this source SQL instance. How should be my approach to move this single database out of this ? My understanding is restoring this database in the new instance, copying all logins to the new instance and then copying the jobs, DTS packages, alerts, operators only specific to this database will do it. Please let me know if this is exactly what I should do .. Thanks in advance.. Regards, Himansu

Mirroring Multiple Databases On A Single Instance
Can someone explain what does this mean? This is from http://www.microsoft.com/technet/prodtechnol/sql/2005/dbmirror.mspx <quote>However, all these techniques for coordinating client redirection with a database mirroring have an important limitation. Database mirroring occurs only at the database level, not the server level. Be careful if your application relies on querying several databases on a server, or uses multi-part object names to query across several databases. When several databases reside on one server, and they are mirrored to a standby server, it is possible that one of several databases might fail over to the standby but the others remain on the original server. In that case, you might need one connection per database that you are querying, so that you do not attempt cross-database queries on a standby server where only one database is a principal and the remaining are mirrors.</quote> Also I read somewhere that if one mirrored DB fails, all other mirrored DB should also be transferred to the mirror. For example: Let's say Srv1 (principle) and Srv2 (mirror) and Srv3(witness) are SQL servers with only default instances. The SQL instance has 4 DBs (DB1, DB2, DB3, DB4) and all of them are mirrored to Srv2. An ASP.NET application has four seperate connection strings like: objConn1 --> Data Source=Srv1;Failover Partner=Srv2;Initial Catalog=DB1;Integrated Security=True; objConn1.connect(); objConn2 --> Data Source=Srv1;Failover Partner=Srv2;Initial Catalog=DB2;Integrated Security=True; objConn2.connect(); objConn3 --> Data Source=Srv1;Failover Partner=Srv2;Initial Catalog=DB3;Integrated Security=True; objConn3.connect(); objConn4 --> Data Source=Srv1;Failover Partner=Srv2;Initial Catalog=DB4;Integrated Security=True; objConn4.connect(); If DB2 failsover to Srv2 (mirror), why should all other DBs be failedover? Thanks

CREATE ENDPOINT To Expose A Single DB Instance
I have been looking at this statement for allowing access from a remote location to a specific database on my SQL Server (2005) from a client application. Is it possible to do this using this method? I see lots of examples using this to expose Web Services of DB objects, however I need the client application to be able to authenticate to and access all objects in the database. If so, could some one provide a simple example of the arguments to use? For example, which protocol arguments are valid for this? I would like to use SQL Server Authentication. Is this possible? Regards, -Troy

Uninstalling SQL Server 2000 Instance On A Mulitple Instance Platform From Command Line
I have a situation where we need to uninstall a SQL Server 2000 instance from the command line using the REMOVE=ALL option along with the INSTANCENAME option in the uninstall process. This must be done from the command line and not through the operating system. We will then install a SQL Server 2005 instance to replace the old SQL Server 2000 instance. My question is whether or not performing an uninstall using the mentioned options will "break" other SQL Server 2000 instances on this server or will they continue to function normally? I know under SQL Server 2005 the REMOVE=ALL option will remove all the shared components and certain instances will be "broken"; does the same thing happen in SQL Server 2000?

Migrating From SQL2K Named Instance To SQL2K5 Default Instance
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)
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?

Migrating From Named Instance To Default Instance
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
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?

Now, I have multiple rows 20,000 or so, rows from which I need 20,000 reports generated, (so they can be printed and mailed to the clients) How do I design the report that can handle singe or multiple reports instances?

Multiple Instance Cluster
Hi There If i have a 2 node cluster running a single instance (default) and i want to add another instance to the cluster , can i install the second instance as a defualt instance ? Since the cluster instances are referred to their virtual names/ip's and if i choose to intall the binaries of the second instance to a different location is this possible? Since in theory you never have 2 default instances running on a single server but each within a virtual server? Normally i install a named instance but do i have to ? Thanx

Replace Instance Of Multiple Char(32)
I have several fileds in a sql table which holds some text and a hell of a lot of white spaces (char(32)) which is causing some problems when I show the data on the front-end What I want to do is use sql replace function to replace the char(32). However, because there is text I can't do a simple replace as the text will become just one word ! Can anyone tell me how to loop through the field to find the char(32), where the char(32) is greater than say 5 sapces and then replace this with just one single space E.g. a field in a table contains the following : "my text field and loads of spaces then some more text with loads of spaces " I want to replace the char(32) with just one space so it looks like this : "my text filed and loads of spaces then some more text with loads of spaces" Thanks for your help

SQL Multiple Instance Priority Setting
Having multiple instances of sql server on the same Win2K box and assign them to different priorities, for example, Instance A is set to the highest priority for user queries; Instance B is set to medium priority for data maintenance Instance C is set to the lowest priority for other miscellaneous jobs. I know this scenario is not an uncommon practice in the Oracle/Unix environment. My questions is: is this also a proven practice in the Sql Server/Windows shops?

Failed To Generate A User Instance Of SQL Server Due To A Failure In Starting The Process For The User Instance
No wonder Microsoft is giving it away for free. It€™s not worth anything. I am very disappointed in this version of SQL server. I decided to start learning VB so I downloaded and installed VB 2005 express edition and SQL 2005 express. I tried to build a personal website using the starter kit. I kept getting the following error message, for which I have seen numerous postings on this forum. €œFailed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed.€? I went out and bought the Standard version of VS 2005 thinking there may be a feature that the free express version is lacking. I uninstalled the express version, cleaned the registry, deleted all the folders it created and installed the Standard edition. Then I tried to create a personal web using the starter kit and it does the same thing again. I can not create a database file, connect to a database file. I can not create or attach a database on the SQL 2005 express from VS 2005. The SQL server Express seems to be working OK since I can attach to it using Microsoft SQL Server Management Studio Express. There is something about the way VS tries to connect to the database server that is not working. VB does recognize the local computer as a SQL server but can not connect to it. SQL server is set to accept Shared memory, TCP/IP and named pipes for local clients. What is causing this? This is some information on the system I am using: MS XP (SP2) Microsoft Visual Studio 2005 Version 8.0.50727.42 (RTM.050727-4200) Microsoft .NET Framework Version 2.0.50727 Installed Edition: Standard Microsoft SQL Server Management Studio Express 9.00.1399.00 Microsoft Data Access Components (MDAC) 2000.085.1117.00 (xpsp_sp2_rtm.040803-2158) Microsoft MSXML 2.6 3.0 4.0 5.0 6.0 Microsoft Internet Explorer 6.0.2900.2180 Microsoft .NET Framework 2.0.50727.42 Operating System 5.1.2600 I am now to programming but nor computer illiterate. I have been working with MS SQL servers since version 6.5 and have MCSE, Network+, A+ and Security plus certifications. Installing and using VS should not be this problematic. What is wrong with Microsoft?

How To Fix Failed To Generate A User Instance Of SQL Server Due To A Failure In Starting The Process For The User Instance
when I try to connect to an mdf as a power user, --------------------------- Microsoft Visual Basic 2005 Express Edition --------------------------- Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed. --------------------------- OK --------------------------- I was able to do do this before until Saturady when I had to re-install sql server, and express etc due to some system problem on my xp Pro PC. What have I misconfigured? I do see the service SQL Serer(SQLEXPRESS) started under Network Service and SQL Serfver(MSSQLSERVER) started under local system. My power user ID does have modify access to the sql 90 database folders. and to the mdf.

Failed To Generate A User Instance Of SQL Server Due To A Failure In Starting The Process For The User Instance
Hello everyone, I am new in .NET development and currently trying to learn VWB through Microsoft online tutorials. Here is the problem that prevents me from getting further: in VWB, when you right click App_Data and chose "Add New Item" and then select SQL database, the following error message is displayed: "Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed." If I cancel out of it, it does generate mdf file under App_Data folder in Solution Explorer, but when I try to open it, it says: "The item does not exist in the Web directory. t may have been moved, renamed or deleted." and that is where the whole sharade deadends. I can connect via mycomputersqlexpress under Data Connections in Database Explorer (it then adds "master.dbo" to the path) and then create custom tables, but that is not the same, isn't it? I mean, this will not integrate my database tables through default configuration that I am trying to follow? All this happens on local machine. Thanks to everybody who can help! Jeff

Can Multiple Instance In A Cluster Share Disk Resources?
Is there a way for multiple SQL 2005 instances in a cluster to share drives for user databases. Once we install our instances in the cluster using seperate disk resources. Can we then have multiple instances share the same physical disk for user databases only. This is for a test environment. Thanks

Any Help With Returning The Last Instance Of A Multiple Version Record In Joined Tables?
We have an archive table which keeps each instance of a sales order that was archived under a "Verion No" field. Each time the sales order is archived it is entered into the archive tables (Sales Header Archive, Sales Line Archive). What I am trying to do is write a query to return all sales orders but only the most recent archived version. For example this table layout is similar to what I am working with. Version No, Order No and Customer No. are the keys between the Header and Line tables, Customer Name column in the output is from only the Sales Header Archive table SALES LINE ARCHIVE TABLE Version No - Order No. - Customer No -----> (other columns) 1 s-5 1000 2 s-5 1000 1 s-6 2000 1 s-7 3000 2 s-7 3000 3 s-7 3000 1 s-8 4000 1 s-9 2000 2 s-9 2000 Here is what I need to output to show: RESULTS OF JOINED TABLES Version No - Order No - Customer No - Customer Name ---> (other columns) 2 s-5 1000 Something, Inc. 1 s-6 2000 Acme 3 s-7 3000 Company, LLC 1 s-8 4000 Blah & Associates 2 s-9 2000 Acme It should return the last Version No of each Sales order. Does that make sense? It is something probably easy... But, I've spent two days using multiples and multiples of different ways, that just aren't working: I'm about to dropkick my server cabinet...

Named SQL 2005 Instance Multiple Active Recordsets-C# Stored Procedure-Connection String
I am working on a C# stored procedure for SQL 2005, and i've uncovered a couple questions. First a description of the procedure: I have a series of equations taking place to calculate a score based on activities in which the user participated in, that will give them an over all grade or rating. The calculations currently take place in the database, and I am moving this from T-SQL to C# CRL. 1. In order to connect the stored procedure to the database I use a SqlConnection and a SqlCommand to execute either dynamic sql or a stored procedure to return data to a data reader. Is there an easier way to connect to the database? In SSMS if i open up the query it knows what database i am connected to. Do I have to make a sql connection in C# stored Procedures? 2. I have multiple functions within the main C# Stored Procedure that I'm working on. This ends up requiring Multiple Active Recordsets. I must set this withing the connection string. Seeing as I'm using a named instance of SQL 2005, I now must put the userid, password, and server name into the code. Is there a more secure way to connect to SQL Server in a C# Stored procedure that allows MARS? 3. I encryped the connection string, and put it into the assembly, I wrote a decryption class, and in the procedure itself everytime I need to refrence the connection string, I call it, decrypt it, and pass it along. But my code to decrypt the connection string is in the compiled DLL, if the server was ever compromised the encrypted connection string and the key to decrypt it are sitting in the DLL. Is there a config file that I can use for C# Stored Procedures? 4. If I have to keep the connection string in the file, then I need to change that per environment. Example I have 3 test environments before production. So I would need to change the connection string for each file. That may be fine for one procedure, but what if I have 20, that will quickly get of hand? 5. Along the security lines, can the assembly for a C# Stored Procedure be called from outside the assembly? From a command prompt, or by a maliceous program? Or could it be called directly by a .NET application instead of going through a T-SQL Stored Procedure that is using WITH EXECUTE AS CALLER AS EXTERNAL NAME [PROJECTNAME].[CLASSNAME].[METHODNAME] Thanks

Error Message: Failed To Generate A User Instance Of SQL Server. Only An Integrated Connection Can Generate A User Instance
Hello everybody,I was configuring a SqlDataSource control using SQL Authentication mode.I first added a database file (testdb.mdf) through Solution Explorer-Add New Items.

2nd SQL Instance. Pro & Con
Here's our problem: We have our SQL2000 server setup for the collating sequence that a third party, Lawson Software, requires, and are in the process of testing our new Lawson installation. OK so far, however, we want to use this SQL server for non-Lawson databases using the default (non-Lawson collating sequence). I think that we can change the non-Lawson databases individually to the default, but am afraid that down the road, each time we add a database, we'll have to remember to change the setting, and will get tripped up from time to time. Since Lawson will be more static as far as database creation goes, are there any suggestions about how to handle this, such as changing the Server collation back to the default, and set the Lawson databases to what they need ? How about installing a 2nd instance of SQL for the non-Lawson applications on the same server ? Would that keep the Lawson & non-Lawson things more separate ?? Thanks in advance for your help & suggestions.

First Instance Only
Is there a SQL function that will return only the first or top instance of each separate result. For example: Select x,y,z from a When x,y,z appear more than once in the result set, I only want one of them, or the first one, returned. Please do not confuse this question with "select top 1 x,y,z from a" - that is a separate animal. Thank you to all, JR

Instance Name
Hello, This is the present setup. Server A --> sql server 2000 Server B --> sql server 2005 On my machine I point to an instance name of sql server 2000 to use. i.e. sqlserver2000Serverinstance1 On my local machine I have installed sql server 2000 and can use the enterprise manager. Have the Admin rights. I have setup a daily backup job on sql 2000... On server B, I installed sql 2005. Restored the sql 2000 backup onto sql 2005. And now I have the sql 2000 database in sql server 2005. Now I can use the sql 2005 by refering to the serverB name (Not an instance). In Server A, the applications are using a login name (sql authentication) i.e. username, password. Questions 1) How do I install sql 2005 on my local machine (Remember that I have sql 2000) 2) If I should run the setup for sql 2005 on local machine, then during the installation, do I give it an instance name or should this instance name be done on the server i.e. server B ? Thanks

Instance Name
Hi gang, Another question. I'm using SQL Server Express and I went to the Configuration Manager and don't find anywhere the default instance 'SQLEXPRESS', instead I see things like "SQL Server 2005 Network Configuration" and under that "Protocols for MSSQLSERVER". Does this mean that whoever installed Express named the default instance "MSSQLSERVER"? Also from my application I use a connection string to connect to SQL Express using "SERVER=MYSERVER" and it connects fine but when I try to use "SERVER=MYSERVERMSSQLSERVER" or "SERVER=MYSERVERSQLEXPRESS" it doesn't connect. Any ideas? Thanks.
