Hi,

I have developed a set of 20 reports using Crystal Reports shipped with Visual Studio.NET 2005 and ASP.NET.

These reports can be viewed using ASP.NET users.

Recently, I am facing an issue with concurrent users. If there are more than 5 concurrent users, the application fails with the following error message

"The maximum report processing jobs limit configured by your system administrator has been reached.".

This will be continued until the IIS is restarted.

Could you please clarify me whether the above problem is due to the more number of concurrent users ?? And what if I have to scale up the application to support 20 concurrent users. What would be the correct version of Crystal Reports to support 20 concurrent users ?

Please take some of your valuable time to answer my above all questions ??

This is a limitation of Crystal Reports.NET 2005. It is not designed for a steady load of concurrent users generating reports. You will have to upgrade to Crsystal Reports Server edition to handle a larger simultaneous load. CR Server works by queueing up reports and generating them in order. This prevents that error message from occurring.

That means we have to purchase the license of Crystal Reports XI server edition and install the same on the web server. And any idea on the type of code changes required to migrate the existing crystal rerports from CR.NET 2005 to Crystal Reports XI Server edition ?  What would be the timeframe to make all these changes ..

 I am in hurry to submit the estimations to scale-up the current application to 20 Concurrents users (Not more .. not less ...!)  ..  please let me know if I need to provide any more information . ....

Unfortunately I don't have any CR Server experience. So I can't give you any estimates for conversion. Re the licensing you need to talk to a BOBJ sales rep. I"M just not knowledgeable about it. You will need a license for the web server. You probably need the CR Dev edition to get full use of the SDK (but this is a guess b/c the server edition might come with it?) Again talk to a sales rep. Oh yeah - some people have complained that some sales reps aren't up to speed. So if you get a bad one call back to talk to someone who knows the product well.

Wish I could tell you more, but I'm not a CR Server guy. Good luck with it.

Is the 5 user limit just in the split seconds when the reports are generated or is it 5 reports limit opened? I have seen contradictory information on that.

Is it 5 users per report or 5 total reports?

I believe it's 5 active sessions (regardless of rpt file).  You may be able to tweak a timeout parameter so that a user doesn't hog a session for a long time just because they didn't move to a different page with their browser.

I think that the number of print requests handled by the Crystal .Net object can be configured in the register: this is defaulted at 75.

The registry Key is: PrintJobLimit.

The number of concurrent  requests  handled by the engine is 3 but others just wait in a queue.

This was told me by a Business Objects Engineer. Am I misunderstanding something. I am pretty sure I have > 5 concurrent users on applications in .Net and I am not getting errors. I use a crReportDocument.Dispose() call as soon as the report is generated?
