(I am not familiar with JMX but does that allow changes to broker properties also ? I thought it was just a monitoring interface ... ) Can I set memory limit of a queue to zero such that producers cannot write at all while consumers consume all pending messages ? Would that could make the queued messages drop down to zero ? You mentioned about producers blocking until more space is available in a queue. However can this be non blocking so that producer can send messages to other queues meanwhile? (Note that I am trying to stop consumers for maintenance to a particular queue only and broker might have more queues that would keep functioning) This is for non persistent queues. -- View this message in context: http://activemq.2283324.n4.nabble.com/Maintenance-Mode-tp4657353p4657377.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
