| How to increase Java heap space [message #629318] |

I have a report that works on small data sets but not on large ones. I trimmed down the amount of work that BIRT is doing (removing conditional formatting, pushing aggregations into the SQL statement) but I'm still getting the following trace when generating to XLS.
PDF also blows up, and I haven't tested HTML yet.
The problem occurs in the RCP editor and when the report is run from the offline libraries (DOS batch mode). I know there's a way to tell Java at startup to increase memory, but I don't know where that's located in this kind of environment. Any thoughts?

Trying to output to HTML I get this:
Sep 27, 2010 2:09:16 PM org.eclipse.birt.report.engine.api.ReportRunner runAndRenderReport
SEVERE: Error happened while running the report
org.eclipse.birt.report.engine.api.EngineException: Error happened while running the report

I was able once to run the report from the RCP editor with output as HTML and it displayed successfully.
ADDED: Running offline to PDF gives this same error. I'l try from the RCP editor again and see if that still generates the out of heap space issue.

Richard,
The option is -XX:MaxPermSize=256m
what command line are you currently using?

Richard,
Can you try changing the line that contains
%JAVACMD% -cp
to
%JAVACMD% -cp -XX:MaxPermSize=256m

That seems to help. Something is still an issue - this is a Windows box, and the task manager shows the Java process eating 350MB of memory, steadily increasing page faults, 35MB In bytes and 15MB out bytes (those numbers unchanging). I forced a data retrieval limit into the query and am going to see if I can find out where the failure or hang point is. This will help - thanks.
Unfortunately I don't have time to try and replicate this in the Derby database but I'll keep it on my "if time allows" queue.
Richard
