out of PermGen space when generating birt report [message #258106]

Hi,

I'm getting "java.lang.OutOfMemoryError: PermGen space". How do I get BIRT
runtime engine to ask for more space?
In previewing the report it's fine (since I use those vm arguments when I
start up eclipse) but not when I try to generate the report in the server
that I deployed it on.

I read somewhere that you can configure some genxxxx.sh (to ask for more
memory) in a BIRT's runtime engine folder but I can't find that in my
workspace.
Or in some OSGI configuration somewhere.... which I donno where it is.

I'm using BIRT 2.2.1 and JDK1.5.

Thanks,
Maria.

Hi
You may change your eclipse.ini with adding -XX:MaxPermSize=256m
at the end of first line. Depending on your memory avaiability you can
also set it higher or lower, ie 512m 128m etc

Please refer to

My Eclipse is fine, previewing the report in eclipse is fine. It's when I
try to access the report on my server that has problem.

http://localhost:8080/my-report/frameset?__report=test.rptde sign

Greetings
You will need to change the JVM init parameters for your server. If you
are using tomcat for example, you can do the following:
(Linux only?) - place the Java options into the CATALINA_OPTS
environment variable. For example: "-server -XX:MaxPermSize=256m".

For other servers you my try to look at their docs && search to see
where the JVM parameters are specified.

Changed the JVM arguments (added in -XX:MaxPermSize=256m) in my run.conf in
JBOSS. It's not crashing anymore.

Thx.
Maria.

Maria,

There is an issue in the 2.2.1 release of BIRT that will cause "OutOfMemory
PermGen " issues. This will lead to inconsistent product behavior and frequent
crashes. I have blogged the solution to the problem at: http://birtworld.blogspot.com/2007/10/221-memory-woes.html.

In a nutshell, all you need to do is open the eclipse.ini file located in
the ECLIPSE_HOME directory.

Change

--launcher.XXMaxPermSize 256m
to
--XX:MaxPermSize 256m

and the problem will be fixed.

The problem exists in the Platform, and has been resolved for the 3.3.2 build,
but that is not due until this spring. The platform is considering a 3.3.1a
build that will fix the problem.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=203325

Depending on what the platform team decides to do, we may create a new build
of BIRT to resolve this issue.
