Re: question about the store/forward algorithm

Hub and spoke architecture - as you've described - is certainly a valid one. By default, messages are forwarded to brokers that express an interest in the message by themselves having a consumer interested in the remote message. Subscription information is propagated from one broker to the

Reliable web-service messaging via ActiveMQ

I'd like to use ActiveMQ to handle message between web-service. Basically, one service is the client of another web-service. I planning on using asynchronous message to send the request because the client doesn't need to wait for the response. The important constraint I have is I want it to be

Re: question about the store/forward algorithm

To add to that, is there a way to track a message (through some kind of log) as it travels around the network of brokers? -- View this message in context: http://www.nabble.com/question-about-the-store-forward-algorithm-tf4965292s2354.html#a14223572 Sent from the ActiveMQ - User mailing list arc

question about the store/forward algorithm

This may seem to be more of a developer question, but I think it applies here. We are considering using ActiveMQ in a large distributed network. The network is spread all over the world and consists of many small "regions," each of which contains a few servers. At any time, a piece of data can

Memory Leak?

All, We are using ActiveMQ v5, and have found an interesting situation with our sending process. We have just confirmed, that if we turn off the sending, then the process stays up, all day no problems. If we turn on the broadcasting, then we get OutOfMemory errors within a few hours. We s

Re: Distributed commons-collections does not contain a required class

FWIW - I am running an embedded 4.1.1 broker and it comes up fine; no such problem. These are the three jar files in my classpath: spring-2.0, apache-activemq-4.1.1, and xbean-spring-2.8. I am running this under a 1.5 JVM. Joe OLF wrote: > > Hi, > > i'm using AMQ 4.1.1 in an embedded brok

I tried this out, it does appear to solve my problem.Thanks! Can we get it added to the 5.0 release? Jason hbruch wrote: > > I had problems as well using failover with maxRetryAttempts and > PooledConnections. > Might there be a call missing in FailoverTransport to the > transportListen

Distributed commons-collections does not contain a required class

Hi, i'm using AMQ 4.1.1 in an embedded broker. During startup there is a DEBUG message java.lang.ClassNotFoundException: org.apache.commons.collections.map.LinkedMap. The lib/optional folder of the AMQ directory is on the classpath, BUT version 2.1 of commons-collections, which comes with AMQ

Re: Consumer forwarding and failover

I tried following test to see how network of brokers react to broker failure and new broker discovery (bringing dead broker back) : Based on following test I think ActiveMQ-5.0-SNAPSHOT is handling this senario properly. Not sure abt 4.1.1. 2 store and forward brokers (B1, B2) 3 consumer (C1 co
