<div class="jive-rendered-content"><p>In JBoss AS 5.1 , messaging 1.4.3 , I have a queue that I've attempted to make more resilient by changing the RedeliveryDelay and the DeliveryAttempts.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I've set the DefaultRedeliveryDelay on the ServerPeer to 10000 ms and that worked, so far so good.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I had initially set the DefaultMaxDeliveryAttempts (on the ServerPeer, for all my queues) to 10, but the number of redeliveries always appeared to be 5 or 6, in the log it would show:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Message redelivered=6 max=5 sending it to the dlq delegator->JBossMessage[2164239059637043</p><p>6]:PERSISTENT, deliveryId=13</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I increased the DefaultMaxDeliveryAttempts on the ServerPeer to 20, but the number of actual redelivery attempts didn't increase.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I then tried to override this for the particular queue I was interested in to 30, like so:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><attribute name="MaxDeliveryAttempts">30</attribute></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>... but the result was the same. I always checked the JMX console to be sure the settings had been picked up.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I've left the timeToLive on the MessageProducer on the default (0) and have also put in logging on it and on the produced messages to confirm that it is indeed 0.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Is there anything else that could cut down the number of redelivery attempts? .. After all, the queue attribute is called MaxRedeliveryAttempts and not RedeliveryAttempts ....</p></div>
