Hi,

I'm new to Birt.

I'm using table to display records from a scripted data set.

My report is working fine for small dataset with records up to 20000. But when My Dataset increases 100,000 records "out of memory error" exception is coming.

I've set the JVM Heap space parameter of my source class to -mx1200m which worked for my source class Smile

.
But when the source class is used for scripted data source in Birt report, exception is coming.
Based on the research done on web i tried to set Tomcat JVM heap space to -Xms520m -Xmx1024m and -mx1200m also, unfortunately it didn't work.

This is the exception I'm getting
index.php/fa/17301/0/

Please Help me in in solving the issue. Smile

Thanks in advance. Thumbs Up

I'm having similar problems with a BIRT report running through JavaBridge. When it reaches about 10000 lines, I run into "Out of memory error". Also, performance deteriorates really quickly when you start to reach high numbers like this... especially considering the query itself takes about 1 second to execute.

I tried the same trick, which is to set the JVM heapspace to a bigger value, but I still get the error on a consistant basis.

Anyone has a way of solving that problem?

What is your BIRT version and what are you setting the heap space to?

In my case, I used Eclipse Juno and the same settings as Krishna which are:

-Xms520m -Xmx1024m and -mx1200m

I'm also not entirely sure if it's linked to this, but I discovered some strange performance drop with arrays which I inquire about here:

I responded in the other one with a suggestion on how you can recreate a large dataSet to try to reproduce the issue using "sample data", just not the sample database.

Hello Ayyal,

have you tried to set the -Xmx Java configuration on your eclipse environment or on your application server.
It should solve the issue with the memory leak.

In best cases -Xms and -Xmx have the same values because so you avoid internal time switch delays.

Kind regards
