RE: [Openjms-user] what is the maximum queue size that openjms can handle ?

[Tim A. <ti...@in...>]

The number of messages in a queue is limited by the memory
allocated to the JVM.

You have several options:
. increase the memory available to the JVM running the OpenJMS server
  Eg. java -Xmx128m .....
. reduce the memoryCheckInterval. This determines how often
  memory consumption is checked - when available memory falls below the
  low water threshold, the garbage collection service is run:
  Eg.
  <GarbageCollectionConfiguration memoryCheckInterval="30"
                                  lowWaterThreshold="20"
                                  garbageCollectionInterval="120"
                                  garbageCollectionThreadPriority="5">
  </GarbageCollectionConfiguration>

. reduce the garbageCollectionInterval. This determines how often
  the garbage collection service is run, irrespective of the amount of
  free memory.

Note that if you are using a released version 0.7.3.x there were two
memory leaks which have subsequently been fixed in CVS.
These were to do with server side QueueBrowser and Session management -
you would only encounter this issue if you created a lot of
QueueBrowsers and Session instances.

Subject: [Openjms-user] what is the maximum queue size that openjms can
handle ?


Hello everybody,
                          I am using openjms & tried to send messages but it
failed after a certain no. of messages. When the queue size went over 20 K,
it failed. What is the solution for it that the jms doesn't break.
                 Besides I am testing on redhat linux 8.0 but i think there
is a compatibility issue as openjms failed to start.

Please help.
Regards & Thanks in advance :-)
Sujay Santra.
