I am using bitronix but configuring it with spring. At the moment I am getting this when I start more than one ProcessInstance: Caused by: java.sql.SQLException: ORA-00060: deadlock detected while waiting for resource What is the recommended way to have multiple long running process executing the workflow at the same time? (I cant find any documentation on this...) Is doing this even supported with Drools Persistence?

Can you share the stack trace of the error?

My workflows will have a number of "long running processes" which I will implement with WorkItemHandlers. I have created a dummy WorkItemHandler that just sleeps for a number of seconds before calling manager.completeWorkItem(workItem.getId(), null); My problem is that in a unit test I am creating a StatefulKnowledgeSession in one thread then calling start process on it in other threads to start multiple processes. I take it this is not supported because it tries to do persistence things without a transaction. How should I be doing this? Also how can I get my long running process to execute outside of a database transaction?
