Subject Re: Durable subscriptions
Date Tue, 29 Dec 2009 07:02:39 GMT

But in 4.1, if we have durable subscribers, we need not send persistent
messages for subscriber to get them after it is back. I mean, if durable
subscriber is down for some time, and mean while if publisher send some
messages, and when the the durable subscriber is back, it will receive all
messages which were sent when it is down. For this to happen, in 4.1, the
sender can send non-persistent messages also.

But while using 5.3, I observed that for durable subscriber to get all
messages that were sent when it is down, the publisher should send them in
persistent mode. How to rectify this issue, and achieve same behavior as 4.1
with respect to durable subscriptions?
