Open SQL Server Connection Troubleshooting

  
Hello, This is regarding ASP.Net (VB) 2.0 and SQL Server 2008.  My project's (there is only one in my solution) has a "Start Action" set to a "Specific Page" (..\Forms\frmMain.aspx).  Occasionally (though not always) a large number of connections (30+) will be opened prior to the frmMain.PreInit event.  These connections stay open for quite some time.  I am closing all of my connections with extreme prejudice.  In my "finally" clause of my try...catch I have myconnection.close.  Immediately after the "End Try" I have myconnection.dispose (redundant, I know).  I have accounted for all connections.  I placed a breakpoint on frmMain.PreInit and then (sometimes) a large number of connections (used SSMS to run sp_who and sp_who2) will have just opened.  What would open a large number of connections prior to the starting page's preinit event?  I am closing (and then disposing) all of my connections.  I thought that I must be missing a myconnection.close in the "finally" clause, but I have looked repeatedly and cannot find anywhere that a connection is open and then not closed.  Also, I do not believe that I have even opened a connection prior to the frmMain's preinit event.

claims authenticated (FBA) user cannot open a connection to our custom application database

  
We have designed a custom sharepoint site. This site uses a membership provider that I implemented, and the users are stored in our custom application database. These are the steps I follow to reproduce the error: 1. Browse to our site. Select Forms Authentication from the default.aspx selection. 2. Enter in a username from our DB table. This user I have configured as a site collection administrator. 3. Login to the site. The user is authenticated by our membership provider and allowed access (ValidateUser returns true) 4. Browse to a page that attempts to connect to the custom app DB. 5. I get the following error when the page attempts to open a connection to our DB: 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server NOTES: The code that opens the DB connection is running with SPSecurity.RunWithElevatedPrivileges. Our application pool account has access to the database. My user can connect to the database fine as well as the user that our  application pool is running as. I have validated the connection string that is being used in the debugger, and that is correct.

SQL 2005 open connection timeout error

  

We have Microsoft SQL Server 2005 - 9.00.4207.00 (X64)  Enterprise Edition (64-bit) on Windows server 2003 (Build 3790: Service Pack 2) .

Periodically (~ once per 15 min) some db-clients have error messages when open connection (over SQL Native Client ) like:

Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

All timeouts more or equal 15 sec. Less then 15 sec is not acceptable by business rules. Performance counters (cpu,memory,disk etc.) on server does not show bottleneck. Only one sql counter - logins/sec show trouble. When problem exists then this counter = 0. Also dramatically decrease many other counters - sql batch requests/sec, transactions/sec, cpu load and some ones. SQL Server "sleep" few seconds (4 - 5) and then accessible again.

Thanks.

 

 


Named Pipes Provider, error: 40 - Could not open a connection to SQL Server

  

This was originally posted in the SSIS Forum, but a member of the IS team suggested it be moved here.  "Most recently I got this error (Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) so does this mean that SQL Server is still trying to use named pipes even if I only have TCP/IP enabled in SQL Server Configuration Manager?"

I'm having the same issue, and here's our scenario:

  1. Installed SQL Server 2005 Developer Edition on a machine with WinXP SP2 and enabled remote connections over TCP/IP
  2. Installed SQL Server 2005 Standard Edition on a machine with Win2003 SP1 (remote connections over TCP/IP enabled by default)
  3. Attempted to 'Copy Database' from Developer Edition TO Standard Edition using 'Detach and Attach' method and recieved the error on the Win2003 machine: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server
  4. A

The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure

  

I've gone through lot of articles and not one solution worked for me:

I'm having IIS 7 on Windows 2k8 with SSRS 2008.

How SSL is configured: Its configured to access SSL over existing web-site. final url looks like https://url/reports. When I enter this URL I get the error message.

But, if I connect to same site using non SSL website from my local machine, it works fine. For example, if i use VS 2008 web server and connect to it, it works and shows me report, but as soon as I deploy it on webserver having SSL enabled, it just throws this message.

 

Somebody please help me wid this one


Not so important

ExecuteReader requires an open and available Connection. The connection's current state is closed.

  

I am accessing SQL2005 with C# code using  OleDbConnection.

 

A try and catch block catches the following error once a while between the Open() and Close() of the connection:

ExecuteNonQuery requires an open and available Connection. The connection's current state is closed.

 

I do not even have any idea where to start to debug this.  The ExecuteNonQuery() runs a delete SQL query. It works 99.9% of the time. I do not see anything wrong when this error happens. 

 

Any hint would be greatly appreciated.

Hi everyone,

I have Oracle client 10g 32 bit installed on my Windows 7 64 bit machine. I am using System.Data.Oracleclient to talk to Oracle databases running on 8i and 10g server. I have my website setup on localhost as well. When I run my website in debug in visual studio 2010, it fails to open a connection and returns an error code ORA-06413: Connection not open. When I run it under localhost, it opens a connection fine and executes a query alright. But becaue I need to debug the code as it do not generate expected results I need to debug it, but am stuck due to this Visual Studio not talking to Oracle. Any ideas on how to get around this problem.

Thanks.


implications of not closing an open connection declared locally

  

 Hello All.

 

I was wondering about something.  I'm supporting a .NET C# application which has a number of database connections declared locally as IDbConnection with MS SQL Server and NHibernate.  These connections are declared locally and not explicitly closed after a specific operation is performed.  Are these connections automatically closed after the local method is executed, or could these connections be floating around somewhere?  We're having semaphore max out problems, and I'm trying to see if this may be the culprit.  I'm doubtful, as I believe these connections would automatically close, but thought I'd throw out hte possibility.

 

Thanks...

Hello Guys,

I know there were posts before about this issue but contacting the web hoster did not help me.
The oddity is, that the same website files, copied and pasted, connection string altered to point to the
production/live db, published to the httpdocs folder works fine BUT the same web files, copied and
pasted, connection string altered to poin to the dev db, published to the subdomains/dev fodler causes the error below:

When I asked the hoster whats going on, he obsiously that its not his fold because the publishing is
