When rendering reports, oftentimes the application would like to minimize as much of the non-report area of the viewer control as possible.  This is easily accomplished when rendering the report through the built-in report viewer control hosted in the ReportServer web site (http://servername/reportserver...

This is documented behavior, but we see lots of questions on it.  A good mechanism for preventing users from accidently exporting reports to a format that you don’t want (for example, you might know that the report doesn’t render quite right in a particular format) is to mark the extension as “invisible...

One of the criteria that the report server uses to match the provided SessionID with a stored report is that the SessionID has to be provided by the same user that initially created the session. Usually, this is the case. Someone browses the report in IE, they click around to paginate or expand toggles...

The SQL Customer Advisory Team just released a Technical Note comparing SQL Server Reporting Services 2008 vs. 2005 from a scale-up perspective. Its good to see that a lot of the work that we did over this release focusing on performance and scalability (across the board, from the core server/processing...

When you install Reporting Services, we create a few directories: LogFiles ReportManager ReportServer RSTempFiles Most of these are fairly self explanatory. LogFiles... well we put our log files in there. ReportManager contains the Report Manager application (what you get when you browse to http://<server>...

Ok, it has been a little while. But I have been pretty busy lately . His name is Christopher. We have also been pretty busy locking down Katmai to get CTP6 (aka known as the "February CTP") out the door and working bugs. I recommend that people head over towards the "Katmai" forum on MSDN for Reporting...

One of the big pushes for SSRS 2008 has been to reduce the occurrence of OutOfMemoryExceptions caused during report execution.  A lot of work has gone into making this happen throughout the report rendering stack, including significant changes in the report processing engine to move a definition...

Today the first public release of SQL Server 2008 is shipping. Of course, Reporting Services is still there in the box. You can find general information about the release here: https://connect.microsoft.com/SQLServer/content/content.aspx?ContentID=5395&wa=wsignin1.0 There are also some Katmai specific...

I was poking around some other SSRS blogs from folks here on the product team, and I found this post from Lukasz about troubleshooting Reporting Services . It is a great overview of some of the guidance we have given in the form of whitepapers, KB artciles, and a bunch of other sources. I highly recommend...

Reporting Services uses a temporary database for storage of objects which are, well, temporary . For example, report snapshots which are associated with a particular user session as the result of a live execution. Cached report snapshots are also stored here because they begin life as a result of a live...

The posts about things dealing with rsExecutionNotFound seem to be what people find most interesting these days. In order to aggregate the posts into one place, I will be adding links that deal with this error here. Maybe I will add a tag as well... Careful when using rc-Toolbar=false Session...

I'm in the middle of reinstalling Visual Studio, and so I thought I would share an interesting story from a couple of weeks ago. An internal customer (Microsoft-speak for some other team at Microsoft) of Reporting Services was encountering seemingly random rsExecutionNotFound errors when navigating around...

This question came across one of our internal discussion aliases, and it wasn't the first time I had seen it... so I thought it might be interesting to other people as well. Oftentimes, when people configure a load testing tool they set it up so that all of the connections come from the same logical...

You know the one. You try to render a report and you end up hitting the dreaded "An internal catalog exception has occurred" error message. Generally speaking, this is an indication that something very bad happened within the server which is not necessarily due to any particular action you performed...

The SSRS Web Server supports two basic protocols, SOAP and URL Access. The SOAP API is great for managing the catalog and doing some session management within the context of a report session, but is generally not the greatest thing in the world when actually rendering a report. The problem is that since...

SQL Server Express with Advanced Services SP1 shipped a while ago and it includes Reporting Services. There is a bit of an annoying issue though. In the Express SKU, the database engine automatically creates databases with AutoClose on. This behavior means that when all of the connections to the database...

Reporting Services has a notion of a user session. This is not the same as ASP.Net's notion of a user session, and in fact the two are completely orthogonal to each other. SSRS's session maintains information about which report a user is looking at, the data that is in that report (we call this a snapshot...

rsReportNotReady is only supposed to be thrown when a report is configured to run from an execution snapshot, and the execution snapshot has not yet been created. It is a pretty rare occurrence and the whole error code is really meant to cover the small window between setting the report to run from an...

The answer, is quite simply "No." Someone shot a post from Google Groups through my inbox this morning where some people were having problems with session timeouts (they were seeing rsExecutionNotFound exceptions). Their "solution" was to edit the stored procedures that manage user session in our...

Windows Authentication is good stuff, and rightly so many people are using it in their Reporting Services deployments. Lately, there has been quite a rash of questions that people have regarding the inability to connect to their data sources when using Windows Authentication. Usually the scenario is...
