Re: Active MQ 4.1.2 Recovery after persistence database shutdown

I'm not sure if there has been anything reported that would specifically relate to your issue. So much of the code has changed since then so I wouldn't know what would be related or not at this point. It's also possible that it has been fixed from a side effect of another bug fix or the behavior

[ANNOUNCE] ActiveMQ-CPP Version 3.9.3 Released

Hi Everyone, Its official, AcitveMQ-CPP v3.9.3 has now been released. This release fixes the way producers creation is handled so that a failed create attempt will result in an exception being propagated to the caller in all cases. The Wiki page for the release is here:

Re: Active MQ 4.1.2 Recovery after persistence database shutdown

OK, thanks for your answer. I guess I was hoping for too much. But maybe you could just tell me if you have had a past bug that needed to be fixed where messages have been lost? If you could point us to where I could read that for ActiveMQ 4.1.2 or later, that would be very helpful. I've searched

Re: ActiveMQ Object Message to json transformation not working

Since he says he can send a generic JSON message, I assume that is without the "transformation=jms-object-json" message header, the system is properly mapping JSON to a generic Java Object, right? If the custom mapping failed I assumed that would mean the class defined in the

Re: ActiveMQ Object Message to json transformation not working

I would have assumed that object serialization and deserialization would either both happen on the broker or neither happen on the broker, and that if serialization was going to happen (and fail due to a missing JAR) on the broker at dispatch time, deserialization would have had to happen at

I think he's using European-style formatting, and that those numbers are forty-five thousand, ninety thousand, etc. Those numbers sound great to me; I was always getting numbers in the order of magnitude of 1000 like Quinn said, even though I expected to go faster since we only did non-persistent

Yes, file a JIRA, and attach a minimal configuration to reproduce the problem. BTW, from what you describe, I'd expect that this would happen for any client (including a tiny Java test app you could write), which would take Nagios out of the equation. Can you confirm that that's the case? Once

Just to highlight something that might or might not already be obvious: the message consumed advisories are triggered when the message is acknowledged, which might happen before or after the consumer actually processes the message, depending on your ack mode. On Apr 1, 2016 5:12 AM, "Christopher

Re: Activemq HA without shared Database or Shared file system

There used to be a share-nothing master-slave configuration but it was buggy and never worked right and has since been removed. Replicated LevelDB is the only option that doesn't have a singleton resource, though you could make the argument that the Zookeeper cluster is a singleton resource

Re: Is there a way to be notified when a durable subscriber receives a MQTT message?

Take a look at the available advisories: http://activemq.apache.org/advisory-message.html It sounds like you want to get notified when subscribers actually receive the messages so you should look at the ActiveMQ.Advisory.MessageConsumed.Topic advisory topic. On Fri, Apr 1, 2016 at 1:40 AM,

The version of the broker you are using is something like 8 or 9 years old. You are most likely not going to find someone willing to help unless you upgrade to a much newer version. On Fri, Apr 1, 2016 at 2:49 AM, Joel Cambon wrote: > Hello, > > I've lost messages

Is there a way to be notified when a durable subscriber receives a MQTT message?

Publisher sends a persistent message to a topic which has more than one durable subscribers. One or more of these durable subscribers may be offline when the message is sent. Is there any way to get notified when the message is delivered to all subscribers? -- View this message in context:
