Re: Upstream throttling and backlog

Thanks gary, In our case we are using kaha-db here is the exact config in broker.xml file We would have expected a drop in throughput may be 30-40%, but not 90%. The file system that the kaha db directory is pointing to is fairly beefy raid10 local disks. What we

ActiveMQ log question

Hello, Sorry for the repost I don't think I was subscribed properly with my previous attempt. I have a question regarding some messages that are appearing in the activemq.log and what they actually mean. I've recently setup a server running AMQ5.5.0. I've got stomp+nio setup as the transport c

Embedded/distribute borker with NFSV3 locks

I understand that when using MASTER, SLAVE scenario NFSV3 is not recommended because of the way V3 works. But is this also the recommendation when using simple broker of clusters with persistence?

updating to 1.5.1 did not help, although it was extremely old version, no idea where i got that :) -- View this message in context: http://activemq.2283324.n4.nabble.com/NMS-producer-slow-tp3768632p3768702.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.

Re: NMS producer slow

but the queue is empty when the producer tries to enqueue a message. So drainage problems should not be effecing producer when there is nothing to consume at the moment of the producer trying to enqueue right? -- View this message in context: http://activemq.2283324.n4.nabble.com/NMS-producer-slo

NMS producer slow

NMS 1.1.0.1642 and activemq 5.4.1 Sometimes when producer messages to a queue it takes a long time for the message is actually enqueued. The weird thing is that when i produce multiple messages to the same queue quickly then all messages are enqueued quickly the Delay is only when 1 message is en

Re: ActiveMQ performances and JDBC persistence

Hi, Is the transaction mechanism in ActiveMQ is for the whole broker or concerns only the queues involved in the transaction ? Regards Hervé 2011/8/16 Hervé BARRAULT > Hi, > I have the following configuration : > 2 producers send message in a queue using camel producer template. > I have

Re: Upstream throttling and backlog

Thanks for the reply, Gary. We're not doing anything specific persistence-wise with the messages themselves. Broker-wise, persistence is enabled on the external broker, but persistence is disabled on the embedded broker. I believe this problem occurs regardless of persistence being enabled/disab

Re: Activemq and Voice chat

Hi, This is probably a somewhat unusual use case for ActiveMQ. I am not aware of anyone who has implemented something similar before. I am concerned about delays and jitter when dealing with voice data streams. Don't see how you can map these to the abstraction of a single message. ActiveMQ wa

Re: Upstream throttling and backlog

@dan, Are you using persistent messages? If yes, typically dispatching is faster than persisting messages and when the consumers are fast we can by pass storing and syncing to disk if the consumer acks before the disk write has started. As a result, through put can be very high. When we persist,
