Server Error in '/menu' Application.


An error has occurred while establishing a connection to the server.  When connecting to SQL Server 2005, 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) Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

SQLExpress database file auto-creation error:



The connection string specifies a local Sql Server Express instance using a database location within the applications App_Data directory. The provider attempted to automatically create the application services database because the provider determined that the database does not exist. The following configuration requirements are necessary to successfully check for existence of the application services database and automatically create the application services database:


If the applications App_Data directory does not already exist, the web server account must have read and write access to the applications directory. This is necessary because the web server account will automatically create the App_Data directory if it does not already exist.
If the applications App_Data directory already exists, the web server account only requires read and write access to the applications App_Data directory. This is necessary because the web server account will attempt to verify that the Sql Server Express database already exists within the applications App_Data directory. Revoking read access on the App_Data directory from the web server account will prevent the provider from correctly determining if the Sql Server Express database already exists. This will cause an error when the provider attempts to create a duplicate of an already existing database. Write access is required because the web server accounts credentials are used when creating the new database.
Sql Server Express must be installed on the machine.
The process identity for the web server account must have a local user profile. See the readme document for details on how to create a local user profile for both machine and domain accounts.

An Attempt To Attach An Auto-named Database For File (file Location).../Database.mdf Failed. A Database With The Same Name Exists, Or Specified File Cannot Be Opened, Or It Is Located On UNC Share.

Sep 2, 2007

Greetings, I have just arrived back into the country (NZ) and back into ASP.NET.
 I am having trouble with the following:An attempt to attach an auto-named database for file (file location).../Database.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
It has only begun since i decided i wanted to use IIS, I realise VWD comes with its own localhost, but since it is only temporary, i wanted a permanent shortcut on my desktop to link to my intranet page.
 Anyone have any ideas why i am getting the above error? have searched many places on the internet and not getting any closer.
Cheers ~ J

An Attempt To Attach An Auto-named Database For File...failed. A Database With The Same Name Exists, Or Specified File Cannot Be

Mar 24, 2006

I know allot of folks are having this problem and I tried lots of things but nothing works. I understand the problem is coping the SQL Express on another server is the problem - I just not sure what to do?

Version Information: Microsoft .NET Framework Version:2.0.50727.42; ASP.NET Version:2.0.50727.42

This is the last statement on the Stack Trace:

SqlException (0x80131904): An attempt to attach an auto-named database for file e:wwwdata81d0493fwwwApp_DataTestDatabase.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.]
System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) +735091

I checked my server forum and they said I had to name a database:
Example: Database=(unique name);

But this didn't work either.

I just tried a simple web project that has only one database and one table in SQL Express with one sqldatasource and one datagrid. It works fine on my pc but when I use the copy function in Visio Studio 2005 Pro - I can't run the site on the remote server: www.myjewelrydirect.com

I tried coping the database manually. I tried disconnecting the database before I copy it. Below is my connection statement:

<connectionStrings>
<add name="TestDB" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|TestDatabase.mdf;Integrated Security=True;User Instance=True"
providerName="System.Data.SqlClient" />
</connectionStrings>

With all the comments in these forums - this must be a bug.

I have been working on this problem for over 2 weeks - HELP!

Lost Connection With Sqlexpress

Jun 15, 2006

I installed on a w2k/sp4 local machine SQLEXPRESS.

I copied the database also to the localmachine

With the sqlexpressmanager I attached the database. Everythinks looks fine.

I quit the manager, but then I start the manager again. Now the manager can't find the sqlserver.

Timeout Expired is the message.

Why is that? I installed SQLEDXPRESS on a lot of machines. No problems. But those machine the manager lost the connection after the first time.

 

thanks again.

Restore MSSQL Database, Lost LDF-File

Oct 4, 2005

Hi.
I've following problem:
- Customer played with his logical drives in a CPQ smart array
- He played too much: he lost the drive with the LDF-File
- Now the SQL-Server is in a kind of wired mode; you can
start and stop it, but you cannot connect to (neiter 'sa' nor
any other user available before)
In fact the mode is not wired: what shall he do other when
most important file is missing... :o
- The problem for me now is:

> How can I get the Enterprise Manager or Query Analyzer
up and running again to start a restore?

PS: The restore is to be done from a tape-library running
Veritas Backup Exec + SQL-Agent

PPS: Error-log says (what I already know):
2005-10-04 17:18:02.69 spid11 Device activation error. The physical file name 'H:DEVLOG1DEVLOG1.ldf' may be incorrect.

Thanks in advance for assistance.

Regards,
Carsten Loeffler

Lost Index Device File And Database Suspect

Mar 3, 2005

Can anyone help me to recreate the .NDF file if it was lost and not restorable? I have a stored procedure written that will then help me rebuild all indexes on all tables, but I can't seem to figure out how to create the index file again so I can run it. I have tried index files from other databases to no avail. There is no backup to go to.

Removal Auto Schema At Creation Of Table

Sep 11, 2015

I've done already the schemas for all the tables a you suggested.But when I created a new table the dbo prefix (dbo.ADM.NewTable) appears.I'd like this dbo not to automatically appear whenever i created a new table — as it requires me to alter whenever I created a new table.Is this something that is required to determine the creator of the table?Otherwise, I'd like that to remove.

SQL 2012 :: Enable Catalog Startup Auto Execution For SSISDB After Creation?

May 31, 2014

There is a checkbox when you create an SSIS catalog which says "Enable automatic execution of Integration Services stored procedure at SQL Server startup". It's a good practice to have this option on. BUT! How do you verify whether this option is ON or OFF after you have created a catalog and how do you enable it if it wasn't enabled at the time of creating the catalog?

RESOLVED RESOLVED An Attempt To Attach An Auto-named Database For File &&<file String&&> Failed &&>&&>&&> But ONLY After SSE Reinstall

Sep 16, 2007

RESOLVED RESOLVED RESOLVED

DOH! When I rebuilt the OS, I changed the data partition ID's, and didn't remember to change them in the connetion strings

Not great, but better than continuing to bang head against wall.

Would like to say to MS appreciators that the VS2005 reinstall actually went quite well, considering.

===========================================================================





I built an app, works fine. Had the development environment working fine (VS2005 (SP0) and SQL Server Express). It had been stable for months, no problem.


Then I had to reinstall XP Pro...(finally threw too many conflicting programs into it, I guess...)


I managed to get VS2005 reinstalled ok. However, when I opened and compiled my existing app in VS2005, using Cassini, I got the dreaded error:

An attempt to attach an auto-named database for file <file string> failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.

I also get this error for the compiled copy of the app on the same machine, running on IIS. (Where it also previously worked fine).


The Connection strings are all of the form

connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=(specific file string).MDF;Integrated Security=True;User Instance=True"


I appreciate that there are zillions of posts on this issue. I'm hoping that someone might know why this should happen in this particular case.


The thing that's different about this case is that the app was working fine; I have the app deployed on a demo machine and also on a remote server as well as on the development machine.


The only thing that changed is that there was this fresh install of SQL Server Express.


I tried using >> sp_configure user instances enabled','1';RECONFIGURE <<< in SSMSEE, which took, but didn't help.


So something is different in SSE. Since the app is stable everywhere else, I REALLY don't want to go through and adjust the connection strings...MUCH better to figure out what SSE needs to be happy with the existing connection strings...as it was before.

Any suggestions would be appreciated.

Thanks!

EDIT----TRIED SOME THINGS:




Changed folder and file permissions to allow ASPNET full access to the .mdf's and log files (though never had to do this before on the development machine.) No change...

Can see the table contents within the .mdf through SSMSE, and also through Server Explorer in VS2005.

So because the problem happens with both IIS and Cassini, I'm assuming it's got to be an issue between ASPNET and SSE.

EDIT --- TRIED SOME MORE THINGS:

I dimly remember that when I had this problem before, it was that the error message was too "dumb". It wasn't my file that had the permissions problems, it was that the SSE System Databases had to have permissions with respect to ASPNET.

I tried to set that up but I'm a complete newb on this area, so I don't know if I did it right. In SSMSE I created a Login for MyComputer/ASPNET, and gave it all permissions and roles, and then made it an owner for the four system databases...but no joy.

Any pointers on this last piece would be helpful.

EDIT - MORE INFO

An Attempt To Attach An Auto-named Database For File......

Nov 14, 2006

I've read through all the posts in this fourm that are related to the problem I'm getting with this error message on my main form, but none of the fixes seen to solve the problem. So I hope someone can get me pointed in the right direction.

I'm running visual studio 2005 professional, and SQL Server 2005 Express Edition and this is a desktop application. I added the db file to the solution with the Add New Data Source wizard, I can create the datasets and preview the data correctly.

An attempt to attach an auto-named database for file C:Program FilesMicrosoft Visual Studio 8Common7IDEdbInventory.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.

When I run the program the exception is throw in the Settings.Designer.vb code, Public ReadOnly Property for the connection string. The InnerException is this...

{"An error occurred loading a configuration file: Could not find a part of the path 'C:Documents and Settings<UserName><ApplicationName>.vshos_StrongName_1sdf1e34hkn1hqmkn2bgjjwstusfj2sg1.0.0.0user.config'. (C:Documents and Settings<UserName>Application Data...<ApplicationName>.vshos_StrongName_1sdf1e34hkn1hqmkn2bgjjwstusfj2sg1.0.0.0user.config)"}

This folder doesn't exist anywhere on the system, any ideas....

Error An Attempt To Attach An Auto-named Database For File

Aug 1, 2006

Hi,

I've just created my first projects using Visual Studio 2005 and SQL 2005 Express. This is the basic;

One windows service is created that updates a database. The windows service running under "Local system" account
One windows application where a user can see data (and change) from the database
A common business and dataaccess layer/project is used by both applications
Connection string to the database: "Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|DataDatabase.mdf;Integrated Security=True;Connect Timeout=60;User Instance=True"

Both application is located in the same directory. When the computer starts the windows service starts and works perfectly. But when a user starts the windows applications the following error is reported "An attempt to attach an auto-named database for file..A database with the same name exists, or specified file cannot be opened, or it is located on UNC share".

It look likes that only one of my application can connect to the database at a time!

Is it possible to use separate applications to connect to the same database file?

/Robert

Error An Attempt To Attach An Auto-named Database For File

Jan 17, 2007

Hello,

I have seen some solutions of which I tried on this form for the error I am receiving, but I still cannot get the issue resolved.

Here is my case:

I developed an app using SQL Express as the local data source. I published it to my server using the Once Click install feature. When I look in my project viewer, under settings, My db connection strings are listed as follows: Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|TAP_Master.mdf;Integrated Security=True;User Instance=True

From another computer, I navigate to the publish site, install and run the application with no problems. I have on another computer, the same app with an updated version number that I wish to publish, however the difference is is that this published version does not include the database as I do not want the end user to overwrite any existing data that they may have from the previous version.

I publish the updated version, install it but when the app runs, I receive the message, "An attempt to attach an auto-named database for file".

Any suggestions?



Thanks in advance.

Feb 13, 2006

Hello,
I'm have developed a web site with .Net 2.0 and Sql Express. To make a loooong story short, I have managed to lose the myDB.ldf file. I still have the .mdf file but can not get my app to connect due to the .ldf missing. Please help if you can. Many thanks!!!
The error I get is: "Cannot open user default database. Login failed.Login failed for user 'myComputerUser'.File activation failure. The physical file name "D:WebProjectswebProjectApp_DatamyDb_log.ldf" may be incorrect. "

File Creation

Dec 15, 2007


Hi!

I have one package (Primary) that calls 4 Packages(1,2,3,4) throw an SQL Server Connection.
That 4 packages create 4 distinct files from a a Streamwriter.
The files area created in a Script component

I call the execution of the packages from an Web Page that calls the job an execute the package Primary.

The first two packages (1,2) create the file and everithing goes ok.

The third one(3) "blows up" with the exception:

System.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.HandleUserException(Exception e) at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.ProcessInput(Int32 inputID, PipelineBuffer buffer) at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostProcessInput(IDTSManagedComponentWrapper90 wrapper, Int32 inputID, IDTSBuffer90 pDTSBuffer, IntPtr bufferWirePacket)

The next try that i made was to comment in the package Primary the execution of the packages 1,2 and run the package 3,4.

The package 3 run ok and the package 4 blows up with


"System.ArgumentOutOfRangeException: Index and length must refer to a location within the string. Parameter name: length at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.HandleUserException(Exception e) at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.ProcessInput(Int32 inputID, PipelineBuffer buffer) at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostProcessInput(IDTSManagedComponentWrapper90 wrapper, Int32 inputID, IDTSBuffer90 pDTSBuffer, IntPtr bufferWirePacket)"

The next try that i made was to comment in the package Primary the execution of the packages 1,2,3 and run the package 4.

It run Ok.

When the package 3 and 4 blows up they create the file but they don't write.

In all the executions that i made i deleted the files that were created.

When I run the packages from the development solution and using file system connection everything runs.

Here is the code of the script component:


Imports System

Imports System.Data

Imports System.Math

Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper

Imports Microsoft.SqlServer.Dts.Runtime.Wrapper

Imports System.IO

Public Class ScriptMain

Inherits UserComponent



Dim directorio As String

Private textwriter As StreamWriter

Private separador As String = ";"

Private cabecalho As Boolean = True

Dim linha As String = ""




Public Overrides Sub PreExecute()

directorio = Trim(Variables.Directory) & Trim(Variables.FileName)

textwriter = New StreamWriter(directorio, False)

End Sub

Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)



If cabecalho Then

Dim DataProc As String = Row.var1

Dim DataInf As String = Row.var2
DataProc = DataProc.Substring(0, 4) _

& "/" & DataProc.Substring(4, 2) _

& "/" & DataProc.Substring(6, 2)

DataInf = DataInf.Substring(0, 4) _

& "/" & DataInf.Substring(4, 2) _

& "/" & DataInf.Substring(6, 2)



textwriter.WriteLine(Variables.var3 _

& separador & Trim(var1) _

& separador & Trim(var2)



cabecalho = False

End If





Dim var7 As String = ""

If Not Row.var7_IsNull Then

var7 = Row.var7.ToString

End If


With textwriter



linha = Trim(Row.var1) _

& separador & Trim(DataProc) _

& separador & Trim(DataInf ) _

& separador & Trim(var7)


.WriteLine(linha)

End With

End Sub


Public Overrides Sub PostExecute()

textwriter.Close()



End Sub

End Class

In the four Script Components the code is the same only change the value of the variables.

I'm sorry for my English and the variables here in the code were changed so it can be an error in the variables but forget that.

Can anyone help me!?

FTP File Creation Date

Oct 3, 2007

I have a script that is utilizing an FTP task to retrieve files from a Windows FTP site without any issues.
I need to check the dates of the files on the FTP site prior to downloading them as I only need files that have been modified. Since these files are hundreds of MB in size, downloading them first and them checking the date is not an optimal approach.
Can somebody please help me figure out how to check the creation dates of the files on the remote FTP directory?
Thanks!

Dynamic Flat File Creation!

May 14, 2008

I'm trying to read the folder which has flat files and transform it and put it another folder with the SAME original name.
I created a For Eachloop containter and assign it to variable infile. In the data flow I added some transform and flat file destination. currently its reading 3 files and output is only one file.
I would like to create dynamic flat file connection so that it'll create separate files (same name) in different folder.
Thanks,

Dynamic Flat File Creation

Mar 19, 2008



Hi All,


I'm new to SSIS. I have a small problem. In our system we are trying to create flat files based on data from returned from different SQL stored procedures. The configuration settings for creating the flat files are stored in a SQL table.

For example, the config table will look like below :

Feed Id Feed Name Feed File Name Feed Stored Procedure Name
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 Biz C:Biz.txt dvx_GetBiz
2 PG C:PG.csv dvx_GetPG
3 NexT C:NexT.txt dvx_GetNexT
4 Amez C:Amez.csv dvx_GetAmez

The problem is dvx_GetBiz, dvx_GetPG,... all have different number and types of columns. So, I'm not able to create a dynamic Flat File destination depending on the columns returned from the corresponding stored procedure.

Is there a way to accomplish this ?

Pl. help.

Awaiting someones reply ASAP.

Thanks & Regards,
Vidya.

OverWrite SqlExpress .LDF File ???

May 20, 2006

Hi :)
I have a website that uses SqlExpress ...on it i have a database that was working ok ...until i made a few modifications to the database (had a few rows).
I have upload the database (only the .mdf file) to the app_data folder ...but now i get this message :
One or more files do not match the primary file of the database. If you are attempting to attach a database, retry the operation with the correct files.  If this is an existing database, the file may be corrupted and should be restored from a backup.Cannot open database "ArtWork" requested by the login. The login failed.Login failed for user 'NT AUTHORITYNETWORK SERVICE'.Log file 'c:xxxxxxxxxxxxxxxxxxxApp_DataArtWork_log.LDF' does not match the primary file.  It may be from a different database or the log may have been rebuilt previously.
I try to delete the .LDF file but it gives me access denied ...i cheched the permissions for the file and everything is ok
How can i solve this??
Thanks and Cheers
