long running report can not be rendered in Report Manager or through Subscription

I am using a stored procedure which will run about one hour and ten minutes to return a dataset to reporting services to generate a report. The report generation is OK if I run it inside Visual Studio 2005. Once it is deployed, it can not finish. Both cases I set "Do not timeout report execution". I even try to create a subscription to let it run throught. But it still can not finish. The traces information in ReportServer*.Log is like this:

I would like know the reason behind it. How to fix that?. I use Sql Server 2005 developer edition.

Thanx

There is a limit for how long a report will run from Report Manager. You can modify the setting at:

Report Manager --> Site Settings-->Report Execution Timeout-->Limit
report execution to the following number of seconds = 3600 (1 hr)

|||

Thank you for your reply.

Actually I set

Report Manager --> Site Settings-->Report Execution Timeout-->Do not timeout report execution. It still can not produce the report.

Another question is after I set localhost/reports and localhost/reportserver session timeout to 3 hrs and these site's asp.net state management session timout to 3hrs, the localhost/reportserver is not accessable. Maybe it is a reporting services bug. Steps to repeat the scenario: Go to IIS, right click localhost/reports-->Properties-->Click Configuration-->Application Configuration-->Options-->Change session timeout to 180 minutes. To set asp.net state management session timout to 3hrs. right click localhost/reports-->Properties-->Report Properties windows-->Click ASP.NET tab-->Edit Configuration-->State Management-->Set Session timout to 180 Minutes.

So far so good. Once repeating above operations to localhost/reportserver, both sites will become unaccessable.

Your response will be appreciated.

The exception you are hitting is the session access timeout. The viewer control will try to ping back to the server every N-1 minutes (where N is basically the session expiration time). The default session access timeout is 10 minutes, so if the report takes over an hour to render, you will hit this timeout.

You can run into problems when the time it takes to render the report is longer than the session timeout, I would recommend altering the following system properties (you will have to do this via the SOAP API or an rs.exe script since they are not exposed in the management studio UI) to be more on the order of what you expect the report execution to be:

SessionAccessTimeout|||

Actually, rendering the long running report in the report manager is just for test purpose. I will create a subscription to deliver the report to a shared folder using SOAP API. Even for the subscription, the timeout issue still exists. Could you provide me some examples to set session timeout via SOAP API or a re.exe.

Thank you very much.

|||Any news? I have the same issue. Can you explain please which values should be used for these parameters in order to get the report running for more than 1 hour?|||There is a blog about it here

So i did change this for a report that needs 20 minutes but it still fail after 5 minutes with this error in the computer application log
