Forms Data Controls :: Dealing With Timeout On Long SP Execution?
Sep 23, 2010
I am executing a stored procedure that takes about 75 seconds to execute. My page times out while it tries to wait for the resultset. I tried adding Connect Timeout=200; pooling='true'; Max Pool Size=200" but it still times out.
I guess I do not necessarily need to wait for the result set. Is it possible to just send the SQL command with something like (making it up:) command.ExecuteOnServerAndDoNotWait?
I've developed a web application to accept video file uploads and then pass them to a backend service on an external server. The application runs without error on the visual studio debugging webserver, but once on a production iis 6 or 7 server, yields a timeout error at about a consistent amount of time into handling a large upload. Specifically, it errors in the middle of transferring the video file to the external server, once the application has successfully received it from the client. I'm aware of several timeouts to be configured related to the problem, and have done so. The application's web config has been tested with one or both of the following settings
<system.web> <httpRuntime executionTimeout="9999999" maxRequestLength="2048000" /> </system.web> and <configuration> <location path="default.aspx"> (the page at issue that's timing out) <system.web> <httpRuntime executionTimeout="9999999" maxRequestLength="2048000" /> </system.web> </location> </configuration>
And within the initialization of the webrequest made to the external server to send the video received from the client browser:
So with the execution time limits on both the webform as a whole and the connection made to the external server, I'm at a loss for what timeout is left unconfigured, or how to determine such, when I continue to get the following error: Unexpected error executing Brightcove Upload:...........................
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.
I am working with the web application for a Money Chain business group. I have to calculate the full payout for the associate members of the website twice in a month. The problem is, when i am executing a stored procedure which obviously take a long time to process all the associate details and calculate the payout, before i get the result the timeout happens in the server. What can i do to correct this problem?
I am new to IIS7 server I have a ASHX generic handler in ASP.NET, its process some mathematical data depending on the user data (which is hard to predict), mathematical model can use lot of memory and may put IIS server to hold all the other tasks I am trying to limit the memory that ASP .NET process can take and setup timeout limit for the max execution time for this .ASHX process i will be glad if any one can point me to the right direction to resolve this
At my place of work, we have an ASP.NET page that uses the following code to perform a file download. We use this rather than Request.TransmitFile() because the file is coming directly from a zip archive.
private void DownloadStream(Stream stream) { int bytesRead; int chunkSize = 1048576; //1MB byte[] readBuffer = new byte[chunkSize]; while ( (bytesRead = stream.Read(readBuffer, 0, readBuffer.Length)) > 0) { if (!Response.IsClientConnected) break; Response.OutputStream.Write(readBuffer, 0, bytesRead); Response.Flush(); } }
I'm trying to determine a reasonable value for the httpRuntime executionTimeout setting. The files being sent range up to 1GB in size, and some of our users have very slow pipes* to the webserver (think 64K lines). We don't want these users to experience connection resets. However, we want to keep a reasonable timeout value for the rest of the site.
Is there a way to define an executionTimeout setting only for this specific page (or even make it unlimited for that page specifically)? What's the recommended approach? I know we'd probably be better off using a totally different method to serve the files (e.g. FTP), but we don't have the freedom to make that choice. All we can do is modify the code for the site.
Also, I do think these downloads should be compressed before sending, but that's another matter.
*Off-topic question: Is "slow pipe" an annoyingly mixed metaphor? I should probably say "small pipe" instead, but that sounds strange to me in this context. Opinions?
I am experiencing a request timeout from IIS when I run a long operation. Behind the scene my ASP.NET application is processing data, but the number of records being processed is great, and thus the operation is taking a long time.
However, I think IIS times out the session. Is this a problem with IIS or ASP.NET session?
n my ASP.NET application, I have a sqlclient connectionstring in my web.config file, What is the recommended timeout setting for production environment? Default is 15 seconds.My web farm and database cluster are on the same switch, so there should not be much latency.
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]...
Could not find schema information for the element 'httpruntime'. Could not find schema information for the element 'executionTimeout'. Could not find schema information for the element 'maxRequestLength'.
According to this msdn library link this is how I'm supposed to do it,so what am I missing here?
I have a simple page with a gridview who's select and delete are enabled. It is bound to a dataset using the object data source. Clicking delete, I get

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
I am using a Gridview on a webform. Got the editing/updating all working correctly. Problem is, all the data is on one row and it is alot of data. I thought about splitting the data into 2 gridviews but then all of the employee data isn't lumped together like the higher ups want.
I have done research on a DataRepeater as it will give me the formatting I need it but it doesnt support editing.
I have a DDL to filter a gridview by "distance." Works fine, but the list of distances (in the DDL) is getting too long and I would like to norrow it down to "Short", "Medium", and "Long" instead of listing all distances. I have added a column to the Distance table named ClassId and a new table named DClass. I'm having trouble figuring out how to incorporate this idea into my existing DDL-Gridview relationship. Here is the existing code:
I there I have recently created an ASP website wich uses .net 4 and SQL db but soem some reason even displaying 20 records in a gridview is slow... So after some reading I converted the website to a Web Application Project so its compile prior to publish.. But yet again this is a bit slow. pages loading time is not of a bit issue...
I'm building an asp.net mvc app, I want to build up an hierarchical structure, is IHierarchicalEnumerable and IHierarchyData the best way to implement a hierarchical structure?
I am retrieving records from database nearly 380 records and binding them to a repeater control.My page is taking long time to load. how to improve the performance and here is the code of my repeater.
I used SQLMetal to generate a DBML file, which worked fine. The problem is that since this DBML file is so big (185,000 lines at 840Kb) it takes literally hours to load in VS2008. What is the recommended way to resolve this? I tried using a third party tool call SqlMetalInclude to break the DBML up into multiple data contexts, but that tool generates only designer.cs files, not dbml files.
In one grid there is only one column and entries are 100+, all entries are hyperlink entries, but the gridview does not look nice with one column and 100+entries, is there any way I can split that entries in 3-4 coluns to look even.
Now, as you can see I've set up the commandargument, and was expecting to get to that in my code behind file. My code is as follows:
[Code]....
Ok...so far so good, and as long as I'm the only one working on the system it works fine. The problem is if this scenario happens:
* I go to the page and look at the gridview
* Someone else enters a new record into the database, causing the first row to contain a new record (not displayed in my browser)
* I click select.
What happens then is that, for some odd reason, I will get n numbers higher than the one I actually selected (n = num_added -num_removed).
I was under the impression that the commandargument wouldn't change for my session as long as I didn't refresh the gridview...?... There are no ajax or anything else messing with postbacks or viewstate as far as I can see..
