Birt Viewer and export OutOfMemory [message #780440] Tue, 17 January 2012 21:48 Go to next message

I am using the open source Birt Viewer with BIRT report engine 2.6.

Viewer works fine for a large data set but I see OutOfMemory exceptions when I export to Excel (native format emitter from Tribix). Is there any parameter in web.xml that can specify that can leverage disk caching or some form of caching.

JVM: -Xms1024m -Xmx1792m

Number of records are 50k and output report size shouldn't be more than 20MB.

Any suggestion appreciated!

Thanks

Do you have -XX:MaxPermSize=256m set?

Are you running this with the frameset mapping and then exporting to
excel. Using the native xls emitter are you getting the memory error?

I wonder if this issue is because of poi. See

and

Yes, I am using frameset to render HTML report and then exporting to Excel. I was directly using tribix native excel emitter. I didnt modify the plugin.

Thanks for the reply.
