How Many Open Connections Does SQL Server 2005 Express Allow To .mdf File
May 17, 2007
Hi Guys, how many connections does sql 2005 express allow to .mdf file. I stumpled on info on a microsoft site (actually a forum post on msdn) that sql server express allows only a single connection to an .mdf file.
Iam intrested in this because i developed reporting services reports in BIS and iam having problems. If i run a report from report manager, i have to wait for close to 20 minutes before i can be able to run my asp.net application agian. Else if i insert data or retrieve data from my asp.net application, then i have to wait again for 20 minutes or more before i can be able to run my reports else i will get an error that a connection can not be made to the database or that the database is being used by another process.
So in all cases, i have to wait for 20--30 minutes before a connection can be made to the .mdf file. i.e after running a report or after inserting or retrieving data from the database through my asp.net application.
Iam using sql sever 2005 express with advanced services and visual web developer on windows server 2003.
Hi,I have SQL Server Express Edition. I tried working out some ASP.NET Labs in my local system. Here is the link of the Virtual Lab which I tried. http://msevents.microsoft.com/CUI/WebCastEventDetails.aspx?EventID=1032286906&EventCategory=3&culture=en-US&CountryCode=USI recieve this error in my local system. 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)I tried working out solutions from various websites. But the no solution is effective. Could anyone help me in solving this issue.
In my office computer network system (LAN), my Windows XP Pro PC has SQL Server Express and VB 2005 Express installed and I was granted to have the Administrator priviledge to access SQL Server Express. I tried to create a SQLCLR project in my terminal PC. 1) I tried to set up a remote connection to SQL Server Express in the following way: SQL Server EXpress => SQL Server Surface Area Configuration. In the Surface Area Configuration for Service and Connection - local, I clicked on Remote Connection of Database Engine, SQLEXPRESS and I had a "dot" on "Local and remote connections" and "Using TCP/IP only". Then I clicked on "Apply" and "OK" buttons. Then I went to restart my database engine in SQL Server Management. When I went to check SQL Server 2005 Surface Area Configuration, I saw the arrow is pointing to "Service", not to "Remote Connections"!!!??? Is it right/normal? Please comment on this matter and tell me how I can have "Remote Connecton" on after I selected it.
2) After I restarted the database engine (I guess!!), I executed the following project code (copied from a book) in my VB 2005 Express:

I am a new Microsoft VS.NET Express user to do the SQL Server 2005 Express and VB 2005 Express programming by using the example of a tutorial book. Please help and tell me what is wrong in my SQLCLR sep-up and project coding and how to correct the problems.
Hi, I was sent a .bak file which I need to open and place in sql server express. I googled this but did not come up with any clear instructions. Can some please give me a good link that explains this. Thanks
Just a quick question about connection management. My application willnever need more than 1 or 2 connections about at any given time. Also, I donot expect many users to be connected at any given time. For efficiency, Iwould like to keep connections alive throughout the lifetime of the objectsrequiring them, rather than opening a new connection, executing code andthen closing it again. What is the most efficient way of doing this?Should I perform the open/close or just one open when I create the objectand a close when I dispose of it?
I've developed an asp.net 2.0 web app with vs 2005 and am using a SQL Server 2005 Express database. The app works fine locally, but after uploading to the remote web server the following error occures: 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)
How do I go about granting remote connections to SQL Server Express?
Does the web server have to have SQL Server Express installed in order to run apps that utilize SQL Server 2005 Express databases?
Do I grant access locally on my machine or do I have to be on the web server to grant remote connections?
I've been using .net 1.1 with access databases for the past couple of years, so this is all new to me.
Hello. I have SQLEXPRESS 2005 installed on my laptop running Windows XP Home Edition with SP2. I have an application that can connect to the local instance with no problem. The other day, I tried to configure SQLEXPRESS 2005 for a remote connection from my desktop. To date, I have been unable to figure out how to do this.
I have followed the instructions posted at various locations on the internet, but to no avail. While I can configure SQLEXPRESS 2005 to allow TCP/IP connections, I have been unable to restart the server.
Here is the pertinent snippet from the error log:
<time> Server A self-generated certificate was successfully loaded for encryption. <time> Server Error: 26024, Severity: 16, State: 1. 2006-08-14 21:02:27.18 Server Server failed to listen on 'any' <ipv4> 0.

Check the SQL Server error log and the Windows event logs for information about possible related problems.
I have a feeling this problem is due to the way my system is configured, not necessarily how my SQLEXPRESS 2005 is configured. My laptop and desktop are connected via a wireless router, and both machines are running Norton Anti-Virus 2006. I've added sqlserver.exe and sqlbrowser.exe to the exceptions list for the Worm protection on the laptop, i.e., the server machine. There's not a setting at the router that would prevent the server from re-starting, is there?

I have an embedded pc which runs windows ce 4.2. I have created an amplication which use sdf file 2.0 version. So i want to copy this database into Desktop PC and open it with Sql Server 2005. Should i upgrade this database? Will i have problems after upgrade?
I just spent the better par of 3 days creating a prototype in ASP.Net 2.0 and SQL Server Express only to discover that nobody from outside can see it... ERROR with impersonation=true User does not have permission to perform this action. ERROR with impersonation=false Unable to open the physical file "c:inetpubwwwroot------.mdf". Operating system error 5: "5(Access is denied.)".An attempt to attach an auto-named database for file c:inetpubwwwroot-----.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share. What makes this so difficult? What am I missing?
I have a laptop and a desktop that I both installed VWD and SQL Express. from my laptop, i see my laptop's name in the Server Name under data connections, but on the desktop, I only see an older Win2K Server with SQL 2000 in the list. Anyone know why my desktop doesn't show it's NAME?I can create new tables, users and all that stuff from the Management area. Thanks
Would be very pleased if anyone knows a solution to my prob.
I connect via ODBC (ADO) within Active Server Pages with an SQL Server 6.5 database. The connection is opened at the top of the pages that need the database, and closed at the end of each individual page. Thing is, the connections for one single user are max. around 3 connections (checked that in Performance Monitor), no matter how many times the user opens his browser with the application. However, when say 20 users log on, the max. number of user connections as configured is reached within no time! The connections are not being closed (even with connection pooling on, they increase like hell!). The only way to close them seems to be stopping the MSSQLServer service, but that's something ya don't want, of course.
It's jut plain crazy to increase the number of user connections to around 250 for about max. 80 user connections at one time...
Hi all !Does someone know how many concurrent connections 2005 Express canaccommodate ? The limit on MSDE was 5 before performance drops considerably.Thanks for your help.Sebastian
Well, I'm to the point of giving up. If there was a 1-800 # that charged $400 /minute for support at this point I would pay it! I have been developing an ASP.net 2.0 web application that basically has login security. I have been struggling to get this thing to work. On my local machine it works fine, but when I copy the code (including the ASPNETDB.mdf that is in the APP_Data directory) over to a web server, I get to the login screen but when I attempt to login I get an error. I've tried using the SSEUTIL.exe and was unsuccessful. At this point I don't even know where to start. Can someone please help me??? The error is listed below: Server Error in '/' Application.

Just upgraded to SQL Express 2005 from MSDE for Firehouse. Upgrade went great and the db is accessable and running fine. Except when not used for a while. Then I need to restart the db to allow connections of any kind. If I don't I get an error that the db is not accessable and I can't connect. Everything runs fine after until it goes to "sleep" on me again. We upgraded to make use of the 4GB limit as we were at 1.9GB and MSDE was getting a little unhappy.
Any suggestions? Is this a "feature" and if so, is there a script I can run to kick it into working mode again?
I have an Excel add-in that connects to a SQL Server Express 2005database. I've decided to create a configuration piece for this add-inin Visual Studio 2005 Express. I added a data connection using the dataconnection wizard and all appeared to go well. Anyways when I attemptto open SQL Server Express to administer the database, it was corruptedand I had to restore it.I eventually got it to work correctly (I'm pretty sure I followedpretty much the same steps as before), but I was just wondering ifanyone had experienced problems like this? I find it a bit scary thatit may be that easy to corrupt the database by just creating a dataconnection.

All -- Please help. Is it possible to connect to MDF file without having SQL Server 2005 Express installed on the machine? That is-- can one connect directly to an MDF in the same way and Access MDB file can be used? If no, then is there any way around this? If yes, then are there any limitations? Please advise. Thank you. -- Mark Kamoski
I am new to SQL Server, and migrating part of an Access application toSSE. I am trying to insert a comma delimited file into SSE 2005. I amable to run a BULK INSERT statement on a simple file, specifying thefield (,) and row () terminators. I can also do the same with aformat file.Here is the problem. My csv file has 185 columns, with a mixture ofdatatypes. Sometimes, a text field will contain the field delimiter aspart of the string. In this case (and only in this case) there will bedouble quotes around the string to indicate that the comma is part ofthe field, and not a delimiter.Is there any way to indicate that there is a text delimiter that isonly present some of the time?If not, any suggestions on getting the data into SSE?Many thanks for your input.Cheryl
I attached a SQL database called Cars, using the following code:
Code Block
IF NOT EXISTS( SELECT * FROM sys.databases WHERE name = N'Cars' ) CREATE DATABASE Cars ON PRIMARY (FILENAME = 'C:DataServer FilesCars.mdf') FOR ATTACH GO
I then copied the .mdf and .ldf to another folder, using Windows Explorer.
I then attached the database using the new folder name in my code.:
Code Block
IF NOT EXISTS( SELECT * FROM sys.databases WHERE name = N'Cars' ) CREATE DATABASE Cars ON PRIMARY (FILENAME = 'C:DataNew FolderCars.mdf') FOR ATTACH GO
Now when I go to update my table, I see that I am hitting the .mdf in the new folder.
And, when I do my table updates, I see that I am hitting the .ldf in the old folder.
Two questions: 1. What did I do wrong, that updates are hitting the new .mdf, but the old .ldf? 2. How do I control what .ldf SQL Express uses?
I see references to 'SQL Server Agent' in the help pages, but do not see 'SQL Server Agent' within the application.
I see the reference to the old folder path, within the 'Database Properties Files page', but no possibity to edit the value.
Hello, I have correctly installed sql express 2005 onto my company server. I can connect to the sql express 2005 fine within sql management studio express. I can also connect to it the within visual studio 2005 server explorer. I have my database (MDF) on our server. I am trying to run my application within my client computer. I have changed the connection string property to connect to the server:
My program will only work if there is a local copy of MDF database located within my application directory. If I remove the local copy, it errors "No process is on the other end of the pipe" Is it possible to have my application without the local copy of the MDF? I thought the idea is to have the MDF on the server. Then my app would not have the MDF copy!?
