For example which nodes would ksessions and process instances be active in ? How to load balance/route requests and events (eg. start task, complete task, async, etc) to appropriate ksessions/process instances ? Which ksessions would timers expire in ? How to deal with concurrent branches (eg. all branches of parallel gateway for a process instance must be active in same ksession vs. can have multiple branches of same process instance active in different cluster nodes, etc). How to make the solution highly-available ? It would be good if experts could comment on this and provide a clear picture of how jBPM works in truly clustered and horizontally scaled environment. And perhaps if there are upcoming enhancements to address challenges in this area it would be good to get some visibility on this. Also, if there are some common approaches to addressing these challenges with current jBPM versions I would be extremely interested to hear of these.

Did some google searches and did not find anything useful in this area. Has anyone solved this problem ? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/779202#779202] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]

Here is the scenario - we have a business app which has the business process (lets assume its a 10-step process with calls to web services etc) implemented using jBPM. This app is deployed in an appserver in JVM1 & JVM2 in Data center DC1. The both share the same Database DB1. We have the same setup in Datacenter DC2 with DB2 and JVM3 & JVM4. DB1 and DB2 are kept in sync through replication. A request comes in from the user and through standard enterprise load-balancer we routed to DC1 and the process is started in JVM1. It is in step 5 and the JVM1 crashes. We want the JVM2 to automatically pick the process and continue from step 6. This is one use-case. The other use-case would be when the Datacenter DC1 goes down and needs to be picked by either JVM3 or JVM4 in DC2. Any thoughts ? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/779210#779210] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
