JBoss has no built-in mechanism for exchanging state between 2 clusters. Do you really need 2 three node clusters? Can you use 1 six node cluster?
JBoss has no built-in mechanism for exchanging state between 2 clusters.
That being said, session replication is not attainable among multiple clusters?
I know I may be re-stating the original question, but I want this to be clear...
I do have the option of 1 -six node cluster, however, I needed this information to determine whether that is the route I need to take. (does that make sense?)
You will have to forgive me, I am quite new to the concept of clustering. Could you maybe elaborate some on the complete capabilities of session replication that Jboss AS 4.2.1 has?
Also, FYI, I am using Apache - mod_jk as my load-balancer for each cluster. Is there a way to obtain similar communication using them?
Thank you so much for the reply.
I've done some reading, & I understand now that multiple clusters cannot exchange state. You were exactly correct when you suggested a 6 node cluster. However, I need communication in this cluster to be both vertical and horizontal. (Among all nodes) If I am not mistaken, this is the default configuration anyway... Is this right?
Also, do you have any advice on optimizing the communication between nodes? I have read the suggestions in the Server_Configuration_Guide, but I was hoping you may have a little more than that...
Thanks in advance for your reply!
