Viewer running out of memory with large data sets [message #200182]

I'm creating a table with a data set of around 100,000 rows.

The report i created generates fine in the developer and i'm able to
preview it in HTML and PDF.

But when i deploy the report online with the BIRT-viewer application I'm
running into issues. To start with I'm using JBoss 4.0.1 on Windows . The
birt-viewer application is deployed in the serverdefaultdeploy directory
of my JBoss instillation.

When I run my report and limit my dataset to smaller sizes the page will
generate fine. But when I increase the range I get a pop up box giving an
exception.

The only error message in the box is:
java.lang.ClassCastException:java.lang.OutOfMemoryError

Stack trace: is blank

Is there any way to increase the memory size of the birt-viewer so i can
get the report to process?

You should be able to set the mem sizes for JBOSS in the run script.
Just look for the Xms and Xmx settings.

Hey,

Does this imply that the maximum size of a report is constrained by
available memory?

Thanks,
Shaun

This model is being slightly changed for 2.1.2 (Feb 2007).
It currently caches data but I believe the report may be in memory.
2.1.2 should have a page at a time in memory, I believe.
