Re: offline Durable Topic Subscribers issue in activemq 5.15.8

Hello Tim, What I meant wrt to 7/8 broker is as follows: 1. I have one frontend broker which only have topics. These topics are then subscribed by the backend broker 2. Each backend broker can have many routes, which means that a single backend broker(with n number of queues) can subscribe to a

Re: offline Durable Topic Subscribers issue in activemq 5.15.8

What does "7/8 backend brokers with a lot of routes" mean? My description of your setup specified either a broker or a master-slave pair of brokers for the backend, and you agreed that my description was correct. How did we get from there to "7/8" backend brokers? Also, can you re-confirm that the

Hello Tim/JB, Also one more information. I tried to reproduce the issue with 1 frontend (with 1 topic) and 1 backend (with 1 camel route) and I was not able to reproduce it. I saw the issue after 7/8 backend brokers with a lot of routes. Regards Ashish -- Sent from: http://activemq.2283324

Re: offline Durable Topic Subscribers issue in activemq 5.15.8

OK, so I want to make sure I understand this correctly. You have two brokers (or is that two failover pairs?): frontend-standard-01 and backend-broker-name-1. The brokers are not configured in a network of brokers, though you're using your Camel routes to move messages between them. You have some

Re: offline Durable Topic Subscribers issue in activemq 5.15.8

Also, to be clear, I don't believe that KahaDB has anything to do with this problem. The issue appears to be that the client ID assigned to the subscription on reconnection doesn't match the previous connection's value, which is independent of the persistence store type. Tim On Thu, Nov 21, 2019,

Could you please share that configuration? I didn't understand from your earlier message that you were creating your subscriptions using Camel, which adds another technology, and another potential source of bugs, into the mix. Are both of your consumers staying up while the broker is restarted? A

Ashish, are you setting the clientID setting on your clients, as documented at the bottom of https://activemq.apache.org/how-do-durable-queues-and-topics-work.html? If not, then on reconnection it may be that the new connection is getting a different client ID, resulting in a different subscriber n

If the problem is still occurring with regular KahaDB, then KahaDB probably isn't the problem. Can you share your full broker configuration, rather than just snippets? Tim On Wed, Nov 20, 2019, 8:16 AM Jean-Baptiste Onofré wrote: > Basically the same as you: > > ind
