WCF / ASMX :: Timeout Error Handling - Data Large To Fetch
Jun 8, 2010
My problem is I have handled timeout error in client of WCF error in such a way that if data is large to fetch, after 10 minutes(as all timeout in web config of client are set to 10 minutes) it should show me customize message 'Too many records to fetch, please modify criteria'. It works on my local system as per expected but if I put it in test server(Service is in one test server and Client application in one test server) it gives me following runtime error.
The message could not be processed. This is most likely because the action [URL] is incorrect or because the message contains an invalid or expired security context token or because there is a mismatch between bindings. The security context token would be invalid if the service aborted the channel due to inactivity. To prevent the service from aborting idle sessions prematurely increase the Receive timeout on the service endpoint's binding. The thing is if I set SendTimeout in test server client config less than 20 seconds then it works fine but we should not be limited upto 20 seconds as it is awfully short.
I have an RSS-reader in one of my webservices. I then utilize the webservice using javascript and everything works fine with small to moderately sized RSS-feeds.
But the webservice keeps timing out when I'm trying to use larger RSS-feeds.
ie. this feed from Youtube: [URL]
Javascript VideoModule = { LoadVideos: function () { var ret = RSSService.GetFeed("http://gdata.youtube.com/feeds/base/users/TheOnion/uploads?alt=rss&
Are there any ways in ASP.net to fetch data from the server without extending the session timeout? This needs to be done every few minutes without user interaction until the page is closed.
Additional context, as requested:
The pages in my webapp needs to poll the server every few minutes to check for a particular condition (emergency maintenance scheduled for 30 minutes time, in this instance). When the condition is true, the page will display a message to the user. When the condition is false, nothing needs to happen.
As I understand it, postbacks to the server reset the time until the session expires. We do not want the session to be extended/refreshed/reset/whatever the word is every time the page polls the server. I need a way to poll the server automatically without resetting the session timeout.
I have a database of about 50 tables and some of the tables have more than 9999999 records. When I try to fetch some data on some SQL statements, sometimes it takes more then 5 minutes. I would like to know if there is good searching approach to get data from that much records in many tables.
I am manually maintaining WCF Session. When client login a GUID is given to the client as sessionId. All others methods have sessionId as parameter that client will provide.Every thing working fine. Now how can i manually manage Session Timeout ?
I have an asmx web service I am "Upgrading" to WCF. It's function is to pass a DataTable to the Remote Server. It works fine as long as the dataset contains under 20 records(more or less). Anything greater than that returns the error:
The remote server returned an unexpected response: (400) Bad Request
Everything I searched on the web says I need to increase things like maxBufferSize in my Web.Config File, but like so many others, it has produced no results. This seems like it should be a simple fix.
I am using VS 2010 on Windows 7. All Development and debugging is being done on the localhost. What I currently have for my web.Config file is below:
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 have 3 seperate applications (under the same domain) for which I use Forms authentication with single sign-on.
The 3 applications have different session timeout periods. I was on various articles that when we use forms authentication and specify the loginurl in the <Forms> tag in the web.config, it should automatically get redirected to the login page, when the session timesout. But in my case, it doesn't happen, I think because of different timeout values.
I am trying to upload file in WCF.When I try to upload file I am getting following error message. System.ServiceModel.CommunicationException:The socket connection was aborted.
This invokes an SQL procedure that takes up to 3 minutes to run when invoked from SQL Management Studio with the same argument values.
The default is 30 seconds.
I tried inserting <httpRuntime executionTimeout="300"/>
within the <system.web> section of web.config. This didn't help.
I tried writing this into the client program: -
GDBService.Endpoint.Binding.OpenTimeout = TimeSpan.FromMinutes(5) Dim start As DateTime = Now Recordcount = GDBService.Chartdata1(_ChartType, _FoundIndiid.ToString, Selection, Chartoption, 0, _UserInfo.Userid, _UserInfo.Role) Dim finish As DateTime = Now
I found that Finish was always 30 seconds after Start. Ditto if I set ..."SendTimeout".
I am trying to send System.Data.Datatable from a WCF service, to a C# Windows Forms application. When I execute, I get follwowing message:The maximum message size quota for incoming messages (65536) has been exceededThe datatable I am trying to send can get quite large. What would be the best approach to send the DataTable across without hitting message size limit, or in other words, what are ways around this problem?
I am going to be receiving data in a web service. After I receive this data I will be mapping it to a data transfer object. I want to be able to catch exceptions if the data from the service is missing any of the required values, times out or any data is malformed.
What can I do to generally catch these exceptions?
In my web app, if user clicks a button, I have to kick off a long running task. I have to keep the user informed about the status of execution of the task from time to time. To accomplish this, I create a thread on button click which makes a synchronous webservice call. The webmethod works on a long running task; while the main thread informs the users about the status of execution.
Currently the webmethod call times out in approximately 90 seconds. I want to increase the timeout to 10 mins. I tried setting <httpRuntime executionTimeout="600"/> along with debug="false"; but in vein. Can anyone tell me what I am missing?
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 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]...
When a server error occurs for whatever reasons (YSOD), the server will send a message via SMTP class. In my case, my company employs microsoft exchange and uses NTLM authentication for all domain users. I am authenticating users via NTLA windows integrated authentication. My question is, is it possible to utilize this authentication data, and pass it to the system.web SMTP username/password authentication scheme to send an email to me (the web developer) when the error occurs? I am pretty sure my company requires a username/pwd to send emails via SMPT on the ms exchange server.
In my code behind I can use try/catch blocks to deal with database errors. How can I capture and handle database errors when using a datasource with a dataenabled control? For themost part I'm using ListView and EntityDataSource controls.
I have all my errors handling up and going but now I wish to change the error messages that they display for empty integers.I have been going through my codes but I can't to change that. For now, the error message for all numeric values are "A values is required" and I wish to change it to "<TextBoxName> cannot be empty".
I'm developing my 1st MVC app using nerddinner as sample, appreciated approach. but when I come to handling error in Edit Post action using a partial class of Entitie2(include the FK) and adding roleviolations to a propertie it work just I don't know how I could validate input for a propertie in the other Entite(N:1)?
