My ASP.NET shows error 404 because can't wait for SQL Procedure result

Hi

I have ASP.NET Application. It gets data (report) from SQL Server 2008.
The database is configured to get data updates from other DB servers.

So my problem is:
my application drops error 404 page because SQL query takes 30-60 seconds.
I set Connection Timeout=120.
What else should I do ?

tnx

404 for "Page Not Found". Please make sure page you are requesting is exist.

Well, the page exists, even I set  <customErrors mode="RemoteOnly" defaultRedirect="ErrRequest.aspx" />
so that users not see 404 Page.

 That it not the case.

The problem is - How to make my application wait for SQL Procedure result, and not throw error ?

The error occurs because of that. All the pages are exist, just it does not wait for queru result.

Have you tried increasing the Connection Timeout further to let say 600 for example?  120 might not be enough.

Have you also tried to optimised your data retrieval to reduce the wait time (e.g. setting up indexes, etc.).?  It is possible that you might have some missing indexes and by putting this indexes, it might speed up your data retrieval.

Also, you could try to put a try-catch block at the point data retrieval and re-execute it again in the catch if the error occurred first time.

I hope this helps.

I have dealt with this kind of issue in the past.  The solution is to run the procedure asynchronously.  

Have your resultset put into a holding table with an extra ID column.
Have your procedure insert data into that holding table rather than to a dataset on your webpage.
You have your page kick off the proc and gives it a big long random ID number 98282928122334, but just continue on to the user without waiting, displaying a page with a little hourglass or spinner.
You have a javascript on that page which calls a simple generic handler (ashx) page that checks the temp table to see if there is a recordset with the id 98282928122334.  If there is, then the script redirects to a page that displays the dataset using a simple select from the temp holding table.  (or you can just pull the dataset right into a div on the current page).

Anyway, people don't mind waiting as long as they know that the work is being done.  Also, if you keep extending the timeout, then people are just going to start refreshing that page and kicking off that massive SP again and again.

Good luck.

I even tried to set this value to 1000, but ASP.NET drops error after 5-20 seconds.

Hmm, it sounds logically, but not the required solution in my case (I hope so).

I will try to reindex the DB again, will see what happens.
