Note that ispan doesn't use java.io.serialization though, so this is pretty efficient. But, yes, it might still be a perf issue.

[JBoss Cache: Core Edition] - Re: Distributed model with Jbosscache

by galder.zamarreno＠jboss.com

The fact that all regions where not online at the same time wouldn't be a problem. When a new store comes in, it could retrieve the state from a persistent store or from another node in the cluster. How many retail branches are we talking about here? What type of data would these retail branches share? What type of network links the different branches?

[JBoss Messaging] - Re: Clustering differences versus JBoss MQ

by kennardconsulting

Clebert, Thanks for your input. I am fine to manually failover in my producer, as I control that code. However the problem I'm having is that, upon restarting a cluster node, the MDBs do not 'wake up' and start consuming messages from the HA queue. The code to connect the MDBs is controlled by JBoss (I presume - it's all magic to me :), so I'm unclear how I can do the reconnects myself? Regards, Richard.

JBossMessaging has automatic failover. If you want to control the failover the same style you would do on JBossMQ, you need to disable failover and do the reconnects yourself.

[JBoss Messaging] - Re: Clustering differences versus JBoss MQ

by kennardconsulting

gaohoward, Please, please - I am begging you! I have spent several days on this and one of the main problems is that in all of the documentation and forum postings members of one team keep referring people to another team, who refer people to another team etc. I understand different people have different areas of expertise, but someone needs to take ownership and provide a one-stop, coherent solution to HA-JMS. Given that the FAQ that doesn't work is a JBoss Messaging one... http://www.jboss.org/community/wiki/JBMHASingleton ...could you please take ownership of this issue and verify that, at the very least, your own FAQ works?
