I have few queries about Parallel Execution</SPAN><BR /><BR /><SPAN>1. You have mention Camel Integration for resolving Optimistic Exception during parallel execution. Here I did not see any attachment with process instance id with Camel Seda Queues. Suppose I want to run multiple instances of Parallel workflow that have camel integration. Does it work successfully ? If not, Is there any way to run successful Parallel Tasks in multiple instance scenario ?</SPAN><BR /><BR /><SPAN>2. If we do not integrate parallel workflow with camel integration then optimistic exception occur. Do you have any other way to resolve this issue ?</SPAN><BR /><BR /><SPAN>3. Can optimistic exception remove using pessimistic locking ?</SPAN><BR /><BR /><SPAN>4. Does Camel Integration also help for resolving optimistic exception in other case ? Please tell those scenarios. </SPAN></BODY></HTML> Mon, 07 Apr 2014 08:05:17 GMT sharad 2014-04-07T08:05:17Z Queries about Parallel Execution in Activiti https://connect.hyland.com/t5/alfresco-archive/queries-about-parallel-execution-in-activiti/m-p/173206#M126368 I have gone through http://bpmn20inaction.blogspot.in/2012/12/implement-parallel-execution-in-activiti.html link and implemented at our end.

That's implemented in the Activiti Camel module</SPAN><BR /><SPAN>2. so you have a couple of service tasks executing in parallel and next a parallel gateway join? You can set the service tasks to run exclusive, but then they don't run in parallel anymore. Another solution is not available to my knowledge.</SPAN><BR /><SPAN>3. Activiti uses optimistic locking, and pessimistic locking is not really considered a good practice in general anymore.</SPAN><BR /><SPAN>4. It solves the potential optimistic lock exception for parallel join gateways and multi instance activities.</SPAN><BR /><BR /><SPAN>Best regards,</SPAN></BODY></HTML> Tue, 22 Apr 2014 09:09:01 GMT https://connect.hyland.com/t5/alfresco-archive/queries-about-parallel-execution-in-activiti/m-p/173207#M126369 trademak 2014-04-22T09:09:01Z
