Repeating processes on interval Activiti

[chrispg]

Hi All,

Id like to know how to run a process on an interval basis, say, every hour, or every 2 hours. This would run indefinitely and stop when I manually stop it.

I did have a look on the forums and google but I couldn't find anyone answers. I think an ISO861 solution should do it but I'm not sure on the implementation. I'm open to all solutions though.

Appreciate any diagram designs, posts, sights that can be referenced in your answer.

Thanks for your consideration.

Blessings

Further clarification: Id like the timer event to be configured via a java service task so the timer event can be continually configured once the process is launched.

The Activiti way to do this is using a timer start event: http://activiti.org/userguide/index.html#bpmnTimerStartEvent

Is it possible to read timer event properties from external properties file and to change timer settings without deploying new process version?

No, that's currently not supported. The timers are handled by inserting a row in the ACT_RU_JOB table, with a given date stamp on which it will be executed. But changing the expression, no that is not posible out of the box.
