> Using non-peristant JMS queues.
> I have downloaded the active mq distribution
> apache-activemq-4.2-20070313.102814-31.zip to test the new message cursor
> functionality. We are testing the spooling functionality after running out
> of RAM buffer. We modified the existing ProducerTool and ConsumerTool
> examples that were provided so that we could send messages that are about
> 80KB in size. We set the memory in the xml config file to 512Mb.
> When we first run the Producer tool to publish 40, 000 messages, it runs fine
> and publishes all 40,000 messages. On version 4.1.1, we could only publish
> out about ~5,000 messages before being blocked.
> After running the Producer tool, we ran the ConsumerTool to read all the
> messages in the queue. It successfully read out all 40, 000 messages.
> We then re-ran the Publisher tool to publish 40,000 messsages. However, the
> publisher would only publish 10 messages and just block. We assumed then
> that 10 messages are in the queue. We ran the Consumer but it would retrieve
> 0 messages. It acted as if there were no messages on the queue. Subsequent
> attempt to run Publisher would only publish out 10 messages while subsequent
> attempts to running the Consumer would retreive 0 messages.
> Any assistance with this would be greatly appreciated. We are in the process
> of migrating off the Sun MQ producer and are looking at some open source
> alternatives. With the design of our application, we need functionality
> analgous to message cursors. Re-designing the application is not an option.
