java.lang.OutOfMemoryError
Hello,
I'm running 4.1.18 on RH7.2, with sun's jvm 4.1.1.
I'm getting a lot of "out of memory" errors during expensive processes, like
accessing thousands of lines from a database.
Is there a way to allow more memory space to tomcat in general, or certain
contexts specifically?
The stack trace is enormous, or I'd include it. The problem does seem to
lie with tomcat rather than the JVM.
Thanks,
Matt

Hi Matt -
There are lots of reasons why this could be happening, ranging from a
know memory leak in JDK 1.4.1_01 to database result sets not being
closed or being poorly managed. We'd need to know more about your app to
say for sure.
That being said, you could always increase the heap size with the -mx
option. Alternatively, you could isolate your application a separate JVM
and tune the JVM parameters for the apps needs.
Regards,
Lajos

reference to tomcat engine from a web application
Posted by Asif Jan <as...@cern.ch>.
Hi
Is there any way to get a reference to Tomcat container from a web
application? (through tomcat API)
Thanks
Asif

Anyhoo:
--
export JAVA_OPTS="-Xms1 -Xmx2 -Xint"
export CATALINA_HOME=/opt/more/cowebell
$CATALINA_HOME/bin/startup.sh
( or nohup $CATALINA_HOME/bin/startup.sh & )
--
The above will set your tomcat home and the java options.

JBoss with integrated Tomcat memory question
Posted by ha...@informatiefabriek.nl.
Hi all,
I would like to increase the memory settings for my Tomcat server which is
integrated in my JBoss application Server.
I read in the Tomcat FAQ that I should edit catalina.sh.
So I looked in the file, but exactly what and where should I edit this
file?
Thanks,
Harm de Laat
