Re: consumer queue acknowledge?

After some further study, it appears i need INDIVIDUAL_ACKNOWLEDGE mode. However, what is not clear is how or IF the message is re-delivered if it is not acknowledged. What is AMQ's behavior in this regard? Does it use the JMS message timeout before redelivery? Can someone verify this behav

Re: message lost under persistent and sync sending mode

The main problem here is that it is really hard to repeat. I am using a network of brokers for large distributed application. Message loss happens about 2% of total execution times. That is I execute 100 times of my application, may be 2 times, message lost could happen. Do you have any suggest

Re: Master/Slave configuring clients

Re: Unacknowledged message is not redelivered

Master/Slave configuring clients

We are implementing AMQ's master/slave broker topology to achieve geographic redundancy. Master is hosted on Server A and Slave is hosted on Server B. For geographic redundancy, we will have two consumer apps which will be hosted on the same servers. These consumers will consume a Q named "TEST

Re: Could not correlate acknowledgment since update

ackType=0 is a delivered ack which is used to increase the prefetch within a transaction or with individual ack but it is not critical. The error indicates that the broker does not have knowledge of the dispatch of that message to the consumer, as a result it has no message to ack. This can occur
