Hoe to handle out of memory issue?

chwang Mar 13, 2006 1:34 PM

Hi, Folks,

I sent tons of message to queue to check max messages the queue can hold. Finally I got out of memory error when Queue depth acheived 500.
I wonder how to deal with this kind of issue. because I may have more than 500 clients send the message to the queue.

Thank you!

You can configure the maximum memory used by the JMS cache. If there are more messages, they are written to the backup storage (ie database or file in older versions).

If the default memory is larger than the memory of your JVM,
then the OutOfMemory comes before the cache decides to swap out any messages.

thank you very much

I wonder if I need to set run.bat file for memory in Jboss?

set JAVA_OPTS=%JAVA_OPTS% -Xms128m -Xmx512m

and How can I check JVM memory?

Cuurenlty I don't set database from my queue, I know the messages are persistent. which file these messages are saved to?

Thanks again

Are you going to read the documentation do you think?
