Is that correct? If so, I am questioning if that is a practical strategy (and NOT the session per process instance) because that is "synchronize and suffer" model of concurrency and does not support parallale processing. Of couse, "session per process instance" and "session per request" might work if 1) an external system cordinates timer tasks, and 2) on every event the session info and process info is retrieved/inserted from/to db and unmarshalled to memory. 1 requires temporal task/event cordination to happen outside jBPM (that application developers writes). So, did jBPM really support BPMN 2.0 timer task? Due to 2, anyone trying to have jBPM in a cluster for better performance has another performance issue (with network lag in DB roundtrip or second level hibernate cache etc.). Am I missing something? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/805156#805156] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034]
