I hope that it's possible to create a Jboss Cluster (couple nodes) with the same Jbpm5 configuration using single DB? Something similar to this article http://www.theserverside.com/news/1363588/Scalability-and-Performance-of-jBPM-Workflow-Engine-in-a-JBoss-Cluster
If not, how can improve performance of my JBPM 5?
