[jboss-user] [JBoss Messaging] - Re: MDB and clustered Topics
THanks for the quick reply Tim. I guess a better description of what I'm using is a clustered durable subscription. In that case, would only one receive the message? On another note I do need a topic because on each node I have multiple MDBs, all subscribing to different clustered durable subscriptions.

[jboss-user] [JBoss Messaging] - MDB and clustered Topics
I've tried to answer this question myself through forms and the documentation but I've been unable (probably due to my own misunderstanding). Env: JBoss 4.2.2 JBoss Messaging 1.4.0.SP1 I have a node of 3 servers, and I'm deploying the same ear to all 3. In that ear I have a MDB that consumes from a topic using a durable subscription where I specify the sub name and client id. So what this means is that each server has an instance of the MDB that consumers from a topic using the same sub name and client id. My question is should this topic be clustered? When a message is posted to the topic I only want 1 of the mdb instances in the cluster to get a copy, not one on all 3 machines? Thanks in advance. ~Jonathan View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=4117112#4117112 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=4117112 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

Fantastic! Thank you Tim. The great responses to posts is also something you won't find with other JMS providers ;) Thanks to the messaging team for great all around service! +1 beer to all of you. ~Jonathan View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=4117145#4117145 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=4117145 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
[jboss-user] [JBoss Messaging] - mysql persistence performance - high load + deadlocks
ENV: JBoss 4.2.2 JBM 1.4 SP1 MySQL 5.0.x From within an EJB3 slsb we pump about 600,000K messages into a clustered topic daily using XA transactions, which is consumed by 4 separate clustered durable subscriptions (this occurs in a cluster of 3 jboss nodes). When we use persistent messaging we see lots of deadlocks in mysql and a high unix load. When we don't use persistent messaging the deadlocks and high load goes away. My question is have you all come across this also and is there any configuration work around to lower the load and deadlocks when using persistent messaging?

[jboss-user] [EJB 3.0] - Re: EJB 3.0 RC8 Preview - FD Released
We really wanted to try out EJB3, but the fact that it has been over a month since people noticed the misssing jars and we have to go googling for them really makes me think this project is not ready. I have to admit, a reply from Scott or someone would have been nice.
