Slow Connection To SQL 2005 Express
Jan 22, 2008
I've just moved a website/database application from windows server 2000 and sql server 2000 to windows server 2003 sp2 and SQL 2005 Express SP2. Database intensive pages now take about 40 seconds where before they took 2-3 seconds.
Things I've tried that haven't helped...
- I changed the ADODB connection string
from: sCnString = "dsn=mydsn;Database=mydatabase;uid=myuid;pwd=mypassword"
to: sCnString = "driver={SQL Native Client};server=myserverSQLEXPRESS;Database=mydatabase;uid=myuid;pwd=mypassword"
- Checked that autoclose is false.
What else can I look at?

Hi,
I use a Remote Sql Server Express instance, and I have a strange behavior.. The first connection is really slow and I don't know how to fix that.I read some posts about this topic but I didn't find the right solution.Is there a way to "keep alive" the connection between my IIS server and the SQL one ?I check the auto-close property and it sets to false.
Any help ?

Hi!
I have a SQLServer 2005 running om a 64bit cluster. It is used to run a SharePoint 2007 portal. My problem is that the access to the database from the other servers in the farm is very slow.
I made a test program in C# that creates a standard .Net sqlConnection and runs a simple query 100 times. When run on the database server it takes less than a second, but when I run it from the web frontend server it takes 30 seconds. It never fails, it's just slow. The network connection is fast when copying files etc.
I see nothing out of the ordinary in the event log.
Do any of you have an idea what might be the problem or know how I could try to find the problem?
Thanks!

Hi,
I have got an application running which connects 2 databases and performs an action that copies data from one database to the other database.
When using SQL Server 2000 MSDE, it takes about 5 seconds.
When using SQL Server 2005 Express Edition it takes about 30 seconds.
For testing 2005, I use 'upgraded' databases, so same indexes and data. I tried reindexing the databases, but always get the same result.
My setup string for installing SQL Server 2005 Express is :
/qb ADDLOCAL=ALL INSTANCENAME=DBNAME SECURITYMODE=SQL SAPWD=QWERTY SQLACCOUNT="NT AUTHORITYSYSTEM"
The code (ADO) is something like :
SELECT FROM original database
-- do something with data
INSERT INTO other database
Until EOF
Any idea how to solve this ???
P.S. When perfoming a simple Query on the databases (with 1.000.000 rows result) with SQL Server Management Studio Express, I see 37 seconds for SQL Server 2000 and 33 Second for SQL Server 2005. That is more the result I expect.

Hello,I have a Win2K3 Server with SS2005 developers edition. I am working on aWindows XP Pro workstation which has SQL Server 2000 installed as well asthe SQL Native Client. I'm using an MS Access ADP to connect to the serverand for some reason it's extremely slow, even to the point of throwing timeout errors and "can't generate SSPI context" messages. I've hit the MSwebsite and found info on the SSPI error, but none of the items thatgenerate the error apply to my situation. I've tried using the surface areamanager to change the connection to name pipes, name pipes and tcpip etc,but no luck.Is there anything I should be looking at or any known issues that wouldaffect this kind of performance?Thanks!Rick

Sql 2005 Express with XPP SP2 and the latest MS updates sometimes runs very slow.
A SELECT which should take a fraction of a second can take several 10s of seconds.
I have checked autoclose is OFF for database using
use master
go
exec sp_dboption 'your_db_name','autoclose'
And it is definitely showing as OFF
I've looked at the Activity Monitor and when stalled it shows one or two processes for my database which are sleeping with 1 or 2 open transactions. When I look at their details they are simple select statements.
Often when my computer should be idle SqlServer.exe can be consuming 20 - 30% of cpu
I've noticed that I have TWO sqlservr.exe showing in my Task Manager, Processes display
One sqlservr.exe is 27K using about 17% even tho computer is idle has username NETWORK SERVICE
Other sqlservr.exe is 343K using 0% has user name SYSTEM
I don't know why.

Creating a web application. Running a simple query "SELECT username FROM vwCustomer"
vwCustomer is a view built on top of an Access DB which is set up as a linked server. Within SQL Server that view responds immediately. But when I try to access it from an ASP page it takes over 20 seconds to respond.
Used the following to create the linked server:
EXEC sp_addlinkedserver 'DBName', 'Jet 4.0', 'Microsoft.Jet.OLEDB.4.0', 'c:databasesdatabase.mdb'
GO
EXEC sp_addlinkedsrvlogin 'DBName', FALSE, NULL, 'Admin', ''
GO
The view is simply(this works fine in SQL Server):
SELECT * FROM DBName.db.dbo.customer
The ASP page:
SELECT * FROM vwCustomer
Can anyone give me a hint as to where the bottleneck is? Or how I can figure that out using SQL Profiler or something?
Please help!

All --
Please help.
I have some questions about connection strings.
BACKGROUND...
Note that I am using the "SQL Native Client OLE DB Provider", SQL Sever 2005 Express, ASP.NET, C#.NET, and VS.NET 2005.
Note that I do not want to use the "Attach a database file" type of connection string.
Note that I am using the site http://www.ConnectionStrings.com as a reference.
Note that this "Standard security" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Uid=MyDatabaseUser;Pwd=MyDatabasePassword;" />...does not work and causes the following run-time error...A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)
Note that this "Trusted connection" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Trusted_Connection=yes;" />...works but is less-than ideal because it uses a Trusted Connection rather than a Username/Password combination.
QUESTIONS...
(A) What exactly does the error in Item 4 mean?
(B) Do 4 and 5 imply that one must use a Trusted_Connection for all SQL Server 2005 Express connection strings when the database does not reside in the web application's App_Data folder or use a "Attach a database file" type of connection string?
(C) Are there any alternatives?
(D) What do you suggest?
Please advise.
Thank you.

Hi all,Just wondering if SQL 2005 express edition can be connected remotely. I've set up SQL 2005 Express on a separate machine and am having trouble connecting to it from VWD when creating the websites. Currently I've set up ASP.NET 2.0 Framework on the remote machine with IIS6 using Windows Server 2003 Web Edition. And I am directly editing the website remotely on the server machine from my PC. Could someone please help me in setting up a remote connection from VWD to the SQL Server?I've enabled TCP/IP setting in the SQL Configuration Manager but still getting errors. Could this be an issue with Express Edition? Because if it is I also have a copy of SQL Server 2005 to install. Any direction to resolve in this issue would be greatly appreciated.PS. I'm new to this so pls bear with me. Thanks.

I downloaded SQL Server 2005 Express and some sample databases (incl. Adventureworks_data.mdf), but when I try to Add Connection in VS 2005 to point to this db and use the Test Connection button, it gives the error:
---------------------------
Microsoft Visual Studio
---------------------------
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)
---------------------------
I've tried setting the data source as either "Microsoft SQL Server Database File" or "Microsoft SQL Server", but get the same error.
Any tips on verifying SQL Srv Express is installed correctly? Any ideas on how to solve this problem?
Thanks in advance.

Hi,
i am stuck in a strange situation.
I have successfully built my application setup through InstallSheild 12. Which first installs SQL Express user define instance as a pre-requisite and then install my application files. First time when i run my application (without restarting the pc), it connects successfully with user define instance.
But as i restart my PC and try to open my application, it is not connecting with database.
i am using the following command line to install SQL Express 2005 user define instance:
"/qn ADDLOCAL=SQL_Engine INSTANCENAME=MyInstance SECURITYMODE=SQL SAPWD="test" AUTOSTART=1"
if i change Remote connection to "using both TCP/IP and named pipes" through "SQL Server Surface Area Configuration" and then restart my pc again. My application connects successfully with Database.
Please guide me where i am getting wrong in building setup. do i have to add something in my command line to not get this error

I'm a newbie to asp.net, but I have been a programmer for years.I have a question that I'm hoping someone can give me a good answerfor, I have been trying to set up a site remotely and I've been usingthe login control that comes with Visual Web Developer 2005 Express,this comes with SQL 2005 Express. The remote site is not a companycomputer, but basically a host that I'm paying for. When I deploy onthis remote site and try to log in I get this error:An error has occurred while establishing a connection to the server.When connecting to SQL Server 2005, this failure may be caused by thefact that under the default settings SQL Server does not allow remoteconnections. (provider: SQL Network Interfaces, error: 26 - ErrorLocating Server/Instance Specified)Using the Database Explorer I noticed that on my laptop the databasefile is sitting on my C: Drive. I also noticed that on the remoteserver I deploy to has all my files on their D: Drive. My question isdo I have to set my SQL 20005 Express file up locally exactly the waythe file will set remotely? In other words... If, on the remoteserver, my files will be on D:(url)asp_data... in order for my logincontrol to be able to use it, it has to be set the same way?Also, does that remote site need to be set up with SQL 2005 express aswell? or will the site be able to work off of that file?And Finally, I also have SQL Server 2000, if I wanted to use this login control (the one that comes with Visual Web Developer 2005), how can Ireference this server instead of SQL 2005 Express? It seems Visual WebDeveloper 2005 wants to use it automatically.Thanks in advance

I am having trouble connecting to SQL Server 2005 Express using ASP.NET written in VB.NET (1.1 Framework) in VS2003. I am trying to programmatically connect to the SQL Server. Since this is a redistributable web application and I don't want to rewrite the connection string every time I distribute a copy, is there any way to automatically get a connection string without prompting the end user for one? I can get the server name and the data base name, but I don't know how to get a username. It returns an error saying SERVERASPNET can't log on. Can anyone help?

I have the following problem, and any help would be appreciated. I am running sql 2005 on my production server, and developing websites on my development server running VWD and Sql Express.
I have been looking for the answer to this problem for about a week. When I upload my site to the production server I get sql errors on all the pages with dynamic content. I have looked into the permissions but nothing is working. Has someone had a similar problem and found a solution?
Thanks for any help.

Thanks and hope you will encourge me to use SQL Server .

I just recieved an ASP script with SQL mdf file and I just installed the SQL 2005 express edition. I'm running it in mix mode (don't even undarstend what it means). The script works with the connection string pointing to the developers site.
connStr= "Provider=SQLOLEDB;Data Source=sql385.mysite.com;User Id=myID;Password=myPass; Initial Catalog=hra;"
I got a table called hra_DATA.mdf and a log which i was able to attach to them from the Microsoft SQL Server Management Studio Express panel.
How can i configure the connection to work with my server.
My servername and instance is MTL-SRV100SRV100
Thanks to all

I try to use this conn string but it is not working I think the problem is with the provider
DataBaseSource = "Provider=SQLOLEDB; Password=sa2006; User ID=sa;Initial Catalog=coupon; Data Source=YAELSQLEXPRESS;"
I get error message
Microsoft OLE DB Provider for SQL Server (0x80004005)
[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.
do you know which provider can I use?
or maybe it is a sacurity problem

I know this is an old problem that has been discussed many times but I'm having a problem getting connected to a remote SQL Express server.
I am running SQL Express 2005 on Windows 2003. I am trying to access it from Windows XP PRO. I have read all the articles about enabling remote access, enabling TCP/IP connection etc and have done that. I also created a user in SQL Express to allow for SQL-SA based authentication. I beleive that this my only option since the two systems are not in a Domain, they do not share common user names.
Using SQL Server Management Studio Express(SSMSE), I can see the instance of SQL, but have had no luck in attaching to it. I thought it might be a firewall problem, but I disabled them completely with no help(ZoneAlarm and Windows). The error message(below) seems to indicate that it can't see the specified SQL instance but I've checked the name multple time and I use the browse feature in SSMSE to identify it.
What am I missing? I've tried everything I can think of and I have made this work before so I'm not a total novice at it.
I would appreciate any suggestions...
Thanks

I am attempting to setup a SQL Server 2005 Express database as a backend to an Access MDB, and need to establish an ODBC data source for the backend database. On two different systems (Windows XP Pro and Windows 2003 SBS), I get an error that says I cannot connect to the SQL Server. I get a message that says:
Connection failed: SQL State 08001 SQL Server Error: 2
[Microsoft][SQL Native Client]Named Pipes Provider: Could not open a connection to SQL Server
That is followed by a Login timeout expired and a suggestion that under the default settings SQL Server does not allow remote connections.
I have shared memory, named pipes and TCP/IP protocols enabled, and the firewall set to allow connections on port 1433. And the Express manager seems to work OK.
I see several posts about issues with ODBC, but none of the suggestions seem to help in this situation. Can anyone suggest something to try? Thanks in advance.

Hello,
I am working on porting a Windows Forms VB.net VS 2003 app with a SQL 2000 backend - to using VS 2005 with SQL Express 2005.
I cannot seem to figure out how to set my connection string to work in the new environment. I have already recreated my database in SQL Express 2005 and ported the VS project to VS 2005.
The old string was (in my app.config file):
<add key="ConnectionString" value="workstation id=MAIN1;packet size=4096;user id=sa;data source=MAIN1;persist security info=True;initial catalog=Dbname;password=####" />
Any ideas?
Thanks,
Sam

Named pipes, error: 40 (Remote access services are not installed by default).I don't want the database physically located on the c: drive.I've been looking all over for the solution for this, and can't find it.Advice or direction to reference materials would be appreciated.Tinker

Hello everybody
I`ve installed Visual C# 2005 Express edition for evaluation reasons. After that I also installed Microsoft SQL Server 2005 Express edition also for evaluation. I then downloaed the installation scripts for the Northwind database and tried to install them.
Unfortunately, every time I try to execute these scripts I get the error :
C:SQL Server 2000 Sample Databases>osql -E -i instnwnd.sql
[SQL Native Client]Named Pipes Provider: Could not open a connection to SQL
Server [2].
[SQL Native Client]Login timeout expired
[SQL Native Client]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.
I`ve enabled named pipes in the configuration utility, but to no avail. This is also no firewall problem. It just can`t connect to SQL server. Anybody with similar problems or a possible remedy?

Is it possible to connect to a sql server express over internet or not ?
- I am using a win2003 sp1 server. Freshly installed.
- The server is directly connected to internet.
- For the purpose of the test, I stopped the windows firewall and the IPSec service.
- I stopped SQL server Browser service.
- I find a free port (here : 1401)
- I activated TCP/IP protocol in SQL Server Configuration Manager, and I have selected 1401 as the TCP port in the IPAll sextion of TCP/IP protection (and I remove the '0' of the dynamic TCP Port).
- Restarted SQL server express...
In the sql server log, I get the message "Serveur Server is listening on [ 'any' <ipv4> 1401]"
But I never get an answer from the server.
sqlcmd -S ip_of_the_server, 1401 -U username -P password is working fine if launched on the server. But I always get a timeout error from any PC. Same with a telnet on port 1401.
Any idea ?

Hi
I got an access 2002 application front end with a sql server 2005 express back end. Some of my clients are having some difficulties. After using the application for a while, some of the users are finding that the system just hangs up. It usually happens after the front end application has been running for about an hour (sometimes sooner and sometimes later). There are perhaps 1 to 5 concurrent users and I have checked to see if there are any firewalls stalling it (I think I check all of them)- Is there any way that SQL Server 2005 express could be caused to just stall- This even occurs with the odd laptop. All the appropriate protocols are enabled as well. These databses are not very large.
ANY HELP WOULD BE GREATLY APPRETIATED!!!
Thanks

Good day.
I am trying to look at a friends database that they have developed. Not having used SQL Server Express before I am experiencing problems trying to remotely connect to their database.
He connects locally just fine of course.
I get the error message about remote connectionsand the default settings so I have enabled TCP/IP and Named Pipes as well as cleared SQLSERVER Express in my firewall settings. I also stopped and restarted the service, but still get the same error message.
My connection parameters are like:
Server type: Database Engine
Server name: http://sql.exampledatabase.net (should http be here? have tried with and without same error)
Authentication: SQL Server Authentication (windows authentication? If so, how do I change to such?)
Login: http://username (should http be here? have tried with and without same error)
Password: password
TITLE: Connect to Server
------------------------------
Cannot connect to http://sql.exampledatabase.net
ADDITIONAL INFORMATION:
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.

I just installed SQL Server Management studio express. I am trying to remotely connect to a SQL Server Express 2005 remotely. I was given the server name, user name and password, and used SQL Server authentication. It connected fine, and I was able to get at the intended database.
I then went to ODBC data sources to add this SQL server using SQL authentication. I entered the server, user and password, and I got a nebulous "could not connect" error. I thought is may be because I still was connected in SQL Server Management studio express, so I closed it and tried again with the same error. I then reopened SQL Server Management studio express and tried to reconnect, and got the same nebulous error, and have not been able to connect since.
I tried rebooting and reinstalling SQL Server Management studio express, but had the same result. Does anyone have any idea what I may have done and how to undo?
Thanks,
Steve Colino
