How to schedule a weekly BPM process

[james...@unisys.com]

I have a "housekeeping" BPM process that needs to execute once a week.

Currently, my team has developed a long-running BPM process containing a loop that never terminates. The BPM process diagram has a timer at the end of the loop to reschedule when to start the next loop iteration. If the jbpm server is shutdown and restarted, we are

depending on this active process instance to automatically get restarted by jbpm runtimes and resume the  timer looping behavior.

Is this an appropriate use of a timer?

Are there other BPM mechanisms that would allow the BPM diagram to contain a clean start and end node? Perhaps there is a event-based BPM start node that I have overlooked?

 

Or is it better to have the BPM process contain a "standard" start and terminate node and use the Operating System task scheduler to initiate each new execution of the housekeeping process?

you can use start timer event in your process definition and then use cron based scheduling, see an example here: https://github.com/droolsjbpm/jbpm/blob/master/jbpm-bpmn2/src/test/resources/BPMN2-TimerStartCron.bpmn2

Thanks Maciej.

Your suggestion showed us how to properly use a timer-based Start Event.

Hi Maciej ,

I am trying to learn the jbpm controls and I followed the link that you provided.
My process contains a start node(timer)->script node->end node.
timer node is set with a cron 0/1 * * * * ? now its running every 1 sec. I have changed cron deplyed it again but the previous cron is keep on running.

How can i stop this process to run.

[Maciej Swiderski]

you need to first undeploy the project that contains that process
