Setting JBoss JMS Queue size

[Brian Pipa]

Hi all,

I have a JMS queue setup on JBoss and it works fine. I'm trying to figure out how to set the number of messages on the queue that get processed at a time. I heard/read somewhere that the default was 5 or 10, but I need to change this. I have googled and can't find the answer to this anywhere and I know you can set this. I don't wnat to set the number of messages that can be on the queue at once, but rather, the number of messages that get processed at a time.

Thanks in advance,
brian

Hi Brian,
Not sure if you still need an answer to this, but I will post a solution in case anybody else is looking.

What you need to do is set the pool size of the MDB to the desired number of consumers.

For EJB 3 on Jboss 5.1 to set it to 3 consumers. This can also be done in the XML files but I forget how. A quick google search will answer that for you.

@MessageDriven
(
		activationConfig = {
					@ActivationConfigProperty(
							propertyName = "destinationType", 
							propertyValue = "javax.jms.Queue"
					),
					@ActivationConfigProperty(
							propertyName = "destination", 
							propertyValue = "queue/QueueName"
					
					)			
		}
)

@Pool (value=PoolDefaults.POOL_IMPLEMENTATION_STRICTMAX, maxSize=3, timeout=10000)
public class ProfileScheduleMDBean implements MessageListener {
	public void onMessage(Message message) {
		//do stuff
	}
}
