I deployed my MVC app to IIS 7.0 and I keep getting the following error; ExecuteNonQuery requires an open and available Connection. The connection's current state is closed I dont get this with the app locally on my machine. Where could this error be occurring??
View 2 RepliesWe are currently migrating our test databases to a new server and I am switching one of our sites over to use them. When running the application from my development box it hits the database just fine. However when I compile and push the code out to our test server and try to use the same datbase I get the ExecuteNonQuery requires an open and available Connection. The connection's current state is closed error. I cannot seem to figure out why. Also when I point the site at our old test server it works just fine.

I want to add a connection to the Server Explorer in VS. The Data source is Microsoft SQL Server (SqlClient). After entering in all my information and I click Test Connection, it is successful.
But when I click OK, I get the error:

I've a web form named contest, where users are to register for it. When the register is clicked on, details entered by the user will be saved into the database, but before it will check if the user has already participated in the contest (using AJAX). If the user has already participated, the button will be disabled. The problem is there is an error when I click on the register button.
The error:
ExecuteNonQuery requires an open and available Connection. The connection's current state is closed.
Here's the codes I use:

I am using VS2008 and oracle 10g ODP.Net. The oracle database that I used in the connection is working and tested it using sql plus.The connection string when used in a GriDView works perfectly. Now when I created a new listview control with the same connection it gives an error.Database schema could not be retrieved for this connection. Please make sure connection settings are correct and the database is online

It throws following error

I have an application with a few dbml files to connect to several sql servers in order to import data from one to another using Linq to SQL.
There are 2 connection strings with integrated security and in one I provide user ID and password.
It all works great in the development workstation. I've then wrapped the dll project and deployed the asp.net application to a test server. Then, when I tried to run the application to import the data, I got a connection exception:
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)
I figured out after some debugging the problem is with the DataContext whose connection string is the one I provide user ID and password. Now, the funny part is that the same connection string works if I create a udl file and test it. And again the same connection string works with my development workstation.

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)

In my DAL i have more than 100 methods/Function, each and every method am opening the sqlconnection and closing the connection, this is taking too much of time to establish the connection at every time. So what i expect is one common class will create the SqlConnection that will check if the connection is Broken or Closed then create the connection again else return the connection, how to do this(Also i would like to apply ConnectionPooling).
