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

Advisory messages are not persisted so you should not have any issues with KahaDB by using them. On Mon, Apr 4, 2016 at 5:01 PM, Shobhana wrote: > If you can enable advisories, you can use the solution suggested above by > Tim. > > > > -- > View this message in context: > http://activemq.2283324

If you can enable advisories, you can use the solution suggested above by Tim. -- View this message in context: http://activemq.2283324.n4.nabble.com/Is-there-a-way-to-be-notified-when-a-durable-subscriber-receives-a-MQTT-message-tp4710173p4710345.html Sent from the ActiveMQ - User mailing list

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

Thank you Tim! In our production env, we have disabled advisories since the number of destinations are already high in number and we have this issue (http://activemq.2283324.n4.nabble.com/ActiveMQ-with-KahaDB-as-persistent-store-becomes-very-slow-almost-unresponsive-after-creating-large-s-td470998

Re: Trusted packages on RA

Looks like you need to open a new jira for this to add the setting as I don't see a way to currently set it on the resource adapter. In the meantime you would probably have to use the System property to set it. On Mon, Apr 4, 2016 at 11:35 AM, Adrient wrote: > Hi, > > I have upgraded my Resourc

Trusted packages on RA

Hi, I have upgraded my Resource Adapter to 5.13.1 and I now need to specify Trusted Packages in order to continue using ObjectMessage (http://activemq.apache.org/objectmessage.html). The only thing is that I can't find the documentation that explains how to set that property via the RA. Here i

Re: Force Producer to fail when blocked by slow consumer?

Yes those settings are configured on the server side because it's the server that decides when to block. The broker is only going to throw an exception to the client if those settings have been enabled otherwise the client is just going to wait for space. As you pointed out I think the only other

Re: Force Producer to fail when blocked by slow consumer?

Re: Force Producer to fail when blocked by slow consumer?

There are a couple options you can configure. Take a look at this page http://activemq.apache.org/producer-flow-control.html Look at the sendFailIfNoSpace and sendFailIfNoSpaceAfterTimeout options. These will allow the producer to fail immediately or after a set amount o time instead of waiting i

Force Producer to fail when blocked by slow consumer?

Hey, we have a setup whereby we are sending persistent messages to an MQ in SessionTransacted batches. The problem we are facing is that if the MQ fills up, our producer blocks indefinitely. We dont have control over the server side queue, so we need to be able to abort sending (rather than wait
