Intermediate Timer Catch Event

[archana071]

Hi,

I am new to activiti, and trying to understand and implement a intermediate timer events.

I want to instantiate many processes(say 2000-3000) for intermediate catch event ( which have a timer definition to fire at specific date). So here the timer for each instance may be longer (eg 2-3 months) so could you please tell me does this implementation cause any overhead on the cpu and memory ? (I mean will these process instances (threads) be waiting or go into sleep state  or they are only bought into execution again when timer fires at specific date and time like the timer start event)

Also I want to know if I can update the existing intermediate catch event with a different date at some other point before the timer ends??

Thirdly, could you also tell me if I can attach any identifier along with the instance of my  intermediate timer event so that I can update that specific one later when needed?

Thank you

No, none at all. Once a process instance reaches a wait state it is saved in the database. it can be there forever. No resources are consumed.

Yes, it will map to a Job. That job has a due date that you can change.

Yes, use a businessKey for your process instance or use a process variable.

Thank you for ur reply.
In the update operation as you mentioned it will map to a job, I want to know if you have any Api to update the timer event, or should I write a query on the activitii database explicitly?

Also could u plz tell me if u have an Api to delete timer event?

Thank you
