View 1 RepliesI have a program that calls a thread, which starts an oracle connection and runs a query that takes about 5 minutes to complete. I want the user to be able to cancel the action if desired. When I call the Close() method on the connection, it takes a good 2 - 3 minutes to close the connection, and then the thread aborts. Is there some way I can get the connection to close faster?
View 1 RepliesI am working on a web application which is designed as master and web content pages. I designed login and logout for the application. When logout is clicked, it will call a method to clear the session variables and also some other methods which will clear some data in the oracle tables.
But if the user is clicking on the internet explorer close button, then there is no way to know that the application is closed. For this I got a link where we can write a javascript method and find the unload of the page and execute all of these but pages will be loading and unloading each time user navigates inside the application and I cannot depend on unloading the page.
how can I do all the process of clearing session and other things when user clicks close button of internet explorer.
Also this application needs to be holding the session for more than 1 or 2 hours, so session should not expire till logout is clicked or close button is pressed.
I want to show a popup about browser compatibility to the users visiting my website. I have used the popup in about 5 pages and it would be annoying for the users to see the same popup for more than once when they visit my website. So I am thinking to use a session and kill it when the user closes the poup. IT should not be shown until the browser is restarted.

View 3 RepliesThis morning I found myself dealing with A SQL POOLING ERROR Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached. I did fix this with resetting my pooling and setting a pooling max =100 Anyway now Im starting to rethink how I open connections, dealing with errors and proper closing of connections Would you say this code below is a good way of opening, closing connections (even when errors occurred)
Dim Connection As SqlConnection
Dim myConn As String = (ConfigurationManager.ConnectionStrings("MyConnString").ConnectionString)
Connection = New SqlConnection(myConn)
Try
Dim DBCommand As SqlCommand
Dim dt As New DataTable()
Dim myDataSet As New DataSet
Connection.Open()
DBCommand = New SqlCommand("GetAllCategories_", Connection)
DBCommand.CommandType = CommandType.StoredProcedure
DBCommand.Parameters.Add("@HomePageID", SqlDbType.Int).Value = HiddenChosenVirtualMainID.Value
Dim mySqlAdapter As New SqlDataAdapter(DBCommand)
mySqlAdapter.Fill(dt)
SecondLevelChildDatalist.DataSource = dt
SecondLevelChildDatalist.DataBind()
Catch ex As Exception
'Error goes here
SqlConnection.ClearAllPools()
Finally
'close the connction
Connection.Close()
Connection.Dispose()
End Try

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.

I have a page where I load a couple of dropdown lists from the database (DB). I do this by calling a general function that connects to the DB and gets the data to the dropdownlist. This means that I can have three queries to the DB while rendering one page.
should I close and dispose the sqlconnection, sqlcommand and sqldatareader at the end of this function?
Would it be faster if I left it open for the next call, if you get what I mean, or is it best to close and dispose it every time?
When should i open and close the database connection.and which are best data classes (for e.g dataset, datatable etc) should i use when connection is open or close.

Which the best place to close the connection. Is it in Server side or Client side?
Our site was under Slow HTTP POST DOS attack recently. It's when your server receives a lot of incoming connections and keep them for long time because the sender sends information very slow and server cant serve real users' request - denial of service.
So I decied to reject such POST requests:
void Application_BeginRequest(object sender, EventArgs e)
{
if ( _my_condition_here_ )
{
_reject_the_request_by_dropping_connection_
}
}
The problem is that I can't drop the HTTP connection in asp.net:
Response.End(), throw new Exception(), even Thread.CurrentThread.Abort()
don't close the connection. It waits while sender sends all the fake data, then answer to it with '500 server error' or something. The slow POST attack still will be successful in this case.
How can I just drop the connection?

The reason this question came up, is because if I run my website application with a SQL Server data store, and I terminate the browser (terminating the session), I try to open up SSMS to edit the DB. But I can't access the database because I believe there is still an open connection, even after application termination.
Is it recommended to close the database connection upon session/application closing? Or am I way off on what I'm thinking could be the problem?
