BIRT Does not respond [message #1095208]

Hi,

Need some help:
I am running some report designs through BIRT runtime, but it hangs randomly. Sometime it returns and sometimes it just hangs and sits for hours. Unix truss shows process sleeping and there are no active DB connections. How can I debug it and find what it is doing ?

TIA
J

What is your BIRT version? Any way you can send me a set of reports that I can run and your Java class you're using to run the reports with that you're getting this issue with? This way I can try to see if I'm getting the issue too?

You could always write out to the console from within the report and within your Java class to try to find where your hangup is, too.

Thanks Michael (as always).
Can you please help me on how to put these messages in the report design itself ?

I am trying to restructure the design so that i can share it with you (give me a day or 2), but as I see, it can only be re-produced when there is large number of groups (say > 100)coupled with large amount of data. I will publish the design at the earliest for you to take a look at.
In addition, Java class is simply creating objects and running RunAndRenderTask; are there any parameters or attributes that I can set for performance ? I explored the forum but looks like all the attributes are preset - confused

There are lots of different script methods in the report. You could use System.out.println() to print to the command prompt when you reach a certain method in the report. This would give you an idea of where it's hanging up based on the last script method that you encounter. You might also look at the log files to see if there is anything in there that will help you figure out where it's running into issues.

cool, btw I timed it. I let the process go on and it returned in ~10 hours generating a report of around 5 MB. My analysis says 2 things - one spudsoft appears to have some lower hand on performance than the earlier BIRT (I might be wrong) and second, xlsx grouping function.
I opened one xlsx and it has a heavy grouping function in it. Is there a way to disable the grouping function ? I believe arctorus does that. Thoughts please...

Can you attach a sample report that shows your issue with the grouping function? Thanks! Smile

Here you go. If you open this sample you will see that excel groups it by itself.
But I got around it using ExcelEmitters.DisableGroup. Unfortunately it did not help with performance. I see there are too many calls like below, and when I time it against a small dataset the time shown in ODI query execution just goes 4 times and more....

I am new to this so am not able to make much sense out of below.. is there any thing that you can suggest I should try ? The same design works good with smaller datasets but as it grows it becomes very sad ..

and my apologies, I think I have reached the same point which we are discussing on another thread: http://www.eclipse.org/forums/index.php/t/513229/

I did not realize that these will cross. So perhaps we can merge the two or the way you feel okay with..

We can just continue on in the other one. Smile
