View 4 RepliesAlright, we have two database servers, one is owned by us, one owned by a partner. Our partners have been having issues lately that have been causing us numerous sql timeout errors, which takes down our whole system. We'd prefer to limit the time those queries can take to say 20 seconds max, otherwise quit trying and throw the error (which we can catch with a try/catch block). Couple of questions: Is there a way to set a particular db/connection string to timeout after X seconds? Is this the best way to quarantine that other system? or are there better ways to go about this?
View 2 RepliesI'm used to public facing websites that use ASP.net membership - and when the SESSION vbl's timeout we re-direct to the login page like this
Code:
If Session("Yr") Is Nothing Then
Page.Response.Redirect("~Login.aspx?reason=timeout")
End If
And on the login page we check for that reason and put up a label on the screen saying that things timed out to protect sensitive data. This works fine. Now I'm doing a web site that's in house - and when the users connect they get a BROWSER POP-UP to login with the DOMAIN UN/PW - and once they get past that my default page redirects them to a home portal page. What do I do when my session vbl's expire now? I can't redirect to a login page - there is not one. How do I cause the re-authentication to happen more naturally?
do I handle a session timeout when using a update panel ?When the user session has timed-out and I click a button I get this error Sys.WebForms.PageRequestManagerParserErrorException - The message received from the server could not be parsed.I have tried to set EnabledEventValidation to false on the page but that didnt work, I have also tried to override the preInit on the page...didnt work either.
View 3 RepliesI'm making an ajax call using jquery to an asp.net mvc controller action:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult GetWeek(string startDay) {
var daysOfWeek = CompanyUtility.GetWeek(User.Company.Id, startDay);
return Json(daysOfWeek);
}
When session times out, this call will fail, as the User object is stored in session. I created a custom authorize attribute in order to check if session was lost and redirect to the login page.
I understand the need for a function like DB_Get_Cached("sql string") that hashes the SQL in order to perform a lookup in memcached for the existence of the data.
function DB_Get_Cached(string SQL)
data = memcache_get_data(md5(SQL))
if (!data)
return DB_Get(SQL)
end if
end function
What is a good method to expand this to handle data invalidation or timeout?
I'm thinking in terms of product pages in an e-commerce site, or user details in their profile.
Is there any sample or guideline shows how to properly handle session timeout in MVC applications?

I have developed a web service using ADO.Net entity framework3.5 and LINQTOSQL3.5.
Now i want to increase the connection timeout? How should i ?
We're trying to get connection pooling working with uodotnet and currently failing miserably. When we turn connection pooling off everything works as expected, but when we turn it on we often get timeouts or errors with one of the following trace outputs:
2011-03-28T15:09:28 System.Exception: Non-negative number required.
[Code]....
Not all the requests fail (for example, when run through a load testing tool, 7/20 requests failed with the timeout problem).
It seems that the sessions are remaining in the pool and new attempts to create a session are repeating until the timeout limit is reached (30 seconds). We're using uodotnet.dll version 2.1.1.7196 and UniVerse version 10.3. running on an HP-UX server. We've got a single license on the dev machine we're testing on with 10 connections available in the pool (theoretically!). We're writing an ASP.Net web site, and we create a new session in the Page_Load() event which is passed to all UniVerse routines and then call close on the session in Page_Unload()/Page_Error().
to what we're doing wrong? We expected that connection pooling would improve performance, falling back on the standard mechanism if the pool was full, but whereas the non-pooled version works fine with 20 simultaneous requests, the pooled version regularly fails. We've set the connection pooling on in the application's web.config, setting MinPoolSize to 1 and MaxPoolSize to 10, leaving everything else at the defaults.
I need to set connection timeout in oledb connection string like
stringA= "Provider=SQLOLEDB.1;Persist Security Info=False;User
ID=sa;PWD=password;Initial Catalog=DB;Data Source=127.0.0.1;Connect
Timeout=30" [code]....
What is the difference between connection timeout and command timeout?
In our application sometimes it is showing a timeout error. When we increased the command timeout value to 100(from default 30), its working. Is there any issue in increasing the command timeout value.
We have been getting this Oracle connection pool exception a lot recently for our ASP.NET website. This is the detailed exception message:
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.
This is our connection string
User ID=user1;password=password1;DATA SOURCE=Datasource1
how to set max pool size to 1 so that I can debug it on my local?
what is the recommended pool size for a website with 10,000 users?
I have the problem of 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.

This 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 am getting this error:
"timeout expired. the timeout period elapsed prior to obtaining a connection from the pool"
when I am testing my webiste on production server. Its working perfectly on my local machine but not on production.
Sometimes it works and sometimes not.
We have the timeout value set to 120 in our <form> tag within the web.config. We do not have a session timeout set.. and we have various connection strings.
We are having a problem where a session variable will disappear (become NULL) .. but, the form evidently remains 'open'.. or no re-login is required..... so, my question(s):
1. what is the relationship between form timeout and session timeout
2. how do I set session timeout
I'm working with ASP.Net web services and am having a problem with a long-running process that takes about 5 minutes to complete, and it's timing out. To fix this, I was able to set the executionTimeout on the server's web.config to 10 minutes, and then set the .Timeout property on the Web Service object to approximately 9 minutes. Now, I'm worried that this may possibly cause some other web service calls to sit there for 10 minutes before they time out rather than the previous 90-100 seconds. I know the default on the client side is 100 seconds, but wasn't sure if updating the server's timeout setting would affect this.
Bottom line is - Is it safe to update the server's timeout setting to a long amount like 10 minutes, and rely on the default timeout on the client, or could this end up causing some problems?
I have VS 2010 professional. I am trying to open "ASP.Net Configuration" through Project -> ASP.Net Configuration.
It pops up the Notification about the ASP.Net Development Server localhost but doesn't open ASP.Net Configuration in the default browser.I clicked on the Root Url (by double clicking on the 'development server' at the right bottom from Notification Manager).
It throws following error
"An error was encountered. Please return to the previous page and try again."
Clicking on "How do i use this tool".It opened page with error.
Tool Has Timed Out
We have an UpdatePanel that is showing a gridview with loads of data in it. We have loads of well written sprocs that don't take very long, BUT we have a few horrible ones that take ages.
We do intend to rewrite them but in the interim we have put the ADO.NET commandtimeout up to 180s. The scriptManager.AsyncPostBackTimeout is set to 240s. We want to handle this on the serverside. One of the reports still fails (it's got a couple of nested cursors in it - someone who hasn't had SQL lesson 101 from me!).
Half the time, the nice error timeout message is shown using server side handling of the command timeout. The problem is that the other half of the time the commandtimeout doesn't seem to fire.
Hopefully I am posting this in the correct forum.
I am having a problem with my ASP.Net Web application. The application is developed using vb.net and is linked to a SQL Server database. Let me explain how the application works and the problem I am experiencing. The system is an online web app which allows registered users to create a CV online. One of the pages within the app gives users the chance to add a cover note to their CV. The page that allows them to do this consists of only a textarea control and a button control. The textarea allows users to input up to 4,000 characters.
Once the user clicks the 'Save' button to save their cover note info, the following code then executes.This code checks to see if the CV already has cover note info, if it does, then the application runs an update statement, otherwise, it runs an insert statement.The table within the database which records the cover note information is called tbl_covernote and has three columns, covernote_id (int and autoincrement), cv_id(int), covernote_text (nvarchar(max)).
The error which occurs sometimes is as follows:
Dim dr As SqlDataReader
Dim param(0) As SqlParameter
Finally [code]...
I have an ASP.Net application that makes an AJAX request to retrieve at report. The report can run for a long time so I set the asyncpostbacktimeout in <asp:ScriptManager /> to 600. However, when I try to run the report, if it runs for longer than 90 seconds it fails to come back. I can see in the IIS logs that the POST request succeeded with a 200 status and I can see the time taken is much less than 600.
The web page dutifully waits for the entire 600 seconds before returning with a timeout error:
Error:
Sys.WebForms.PageRequestManagerTimeoutException:
The server request timed out.
Is there any setting I should be checking in IIS? Connection timeout is 900 seconds.
