Delay In Web Service After Idle Time?
Jun 11, 2010Every time my VB .NET Web Service is idle for about 30 minutes or more, the response for the next request is very slow.

View 2 RepliesI have a webservice which returns the content of a pdf.
I've noticed that when I've left the website for a while and I call the method of the service it takes a long time to respond.
My ASP.NET website while trying to connect to the database for first time after a period of inactivity throws an time out exception.
I understand the connections in the connection pool get terminated after some idle time for some reason (Firewall or Oracle settings) and the pool or app doesn't have a clue about it.
Is there any way to validate the connection beforehand so that the first try doesn't throw an exception?
I don't have much control over the DB or Firewall settings. So I have to deal with this is my application.(would prefer if there is any web.config settings)
I am using: ASP.NET 2.0. Oracle server 11g, Microsoft Enterprise Library DAAB to do all my DB operations.
I have a requirement to calculate the Web application idle time. Say the user doesnt use the web application for 15 minutes, then a message needs to be displayed to the user.

View 1 RepliesI have an IIS 6.0-based C#/ASP.NET web site with a SQL server backend.I want to generate some computationally expensive reports (summaries, search engine indexes, etc...) in idle CPU time. I need the reports to be generated from WITHIN the IIS App Pool so it knows the proper configuration settings and (harder to fix) avoids the nightmarish security restrictions I've been placed under.
Can I start threads inside the AppPool's process that won't tie up the CPU, so it can continue serving requests unfettered? If so, how? What code and libraries?
I imagine it involves ThreadPool and thread priorities, but I couldn't find good coverage of low-pri threads and their interaction with the IIS web server and App pool.
[EDIT] [URL] discusses using a Timer for this but doesn't directly state that the .NET framework will insure that the Timer thread is low-priority. This might be a solution, but is that assured?

[EDIT] Interestingly, Stack Overflow itself seems to use IIS background threads for my purpose:

How to retrieve system idle time in asp.net..?
View 1 RepliesGot really strange Firefox issue. Using the Microsoft __doPostBack javascript function in web forms page. Used for tab control, we have got each tab click calling the __doPostBack function. Works ok on my dev machine with all browsers but got a colleague who has an issue if he leaves the page idle for circa 3 -4 minutes. After this delay if he selects a new tab which calls the __doPostBack function the call to theForm.submit(); just hangs and get requested timeout. No .net calls are seen in Firebug. The __doPostBack event is called just theForm.submit() function just doesn't execute. If he does not have this idle time works ok. It is also ok for him on all other browsers.
View 2 Replieswhen i leave my page idle for about 2 minutes.
When i do a postback from my linkbutton it fails.
The browser then shows "Internet Explorer cannot display this webpage" I then also receive a Request Time Out in the event log.
Does anyone have similar experience with this, not sure what could be causing this since it happens on all pages in my application.
i made an web application for my client, he is from usa, I deployed application to [URL], at my local system, the project function proper. But what is happening that at main server the session is destroying automatically, before the idle time. I have been figuring out this problem for long but could not solved it. what may be the reason behind this session out. I am using in process session.

View 7 RepliesI have IIS 7.5 running on windows 7 64 bit machine.
My problem is that in my web application after any page request if the page remains idle for more than 2 mins, it stops responding. For e.g. lets take the following scenario:
1. Initial page request
2. the page stays idle for 2 mins
3. Click a button to save data
4. It takes very long for the aspnet worker process to reach page_load, and firefox shows "connection was reset" message.
I put breakpoint on page_load. It strikes the breakpoint after a long time and also it does not go to the event handler of the button that was clicked.
The web application works perfectly if the page is not kept idle.
I am not using sessions in my web application.
in my page i dessigned Updatepanel within that i placed some input controls(textbox, dropdownlist etc) within that updatepanel i placed one button. now the problem is on production if i idle some time after enter some data and press the button then the button click event not fired, then i refresh the page enter the input then press button then its fired, what is the problem? and how to resolve it? (i didnt included any triggers)

View 1 RepliesI am writing a program to measure the latency(response round trip time) for a web service. I need to have this at client side.
My initial plan is to store the time at which request is sent and then calculate the difference in time when we recieve a response from the web service. Is this the correct way to measure latency of web service. This has some overhead because of storing time and all. How can this be done?
Another option is to attach a timestamp with the SOAP request. But the server should return the timestamp. This will not be possible in case of third party web services.
I've been having issues getting a service to start. I have 2 other services are identical in configuration in just about every way that start fine, but one of them refuses to start and I really need to get it to work today. I can't see any difference in their implementation or config files. I'm receiving the following messages when attempting to start the service after installing it with InstallUtil:The service is not responding to the control function more help is available by typing NET HELPMSG 2186 NET HELPMSG 2186:
Explanation: The service cannot run your command at this time

I have an application where I want to send an email reminder for an appointment 24 hours prior to the event. Users would log in and insert appointments. I would think I would want a background thread running on the server that would regularly check the database (say every hour) and generate an email if there is an event is due within the next day. From what I have read it seems like a Web service might do this. I guess I have a few questions
1) am I on the right track - is this an application for web services
2) can anyone point me to a good resource which can help me create the web service I would need. I would prefer if it is in VB and not C#.
