Hello Folks,
I have a design question to ask. We are having 2 flows, both needs to be run every 30 minutes. But there should be a gap of 15 minutes between both of them. I am using TimeoutNotification to schedule the time. I am deploying the first flow and after 15 minutes I am deploying the second flow, so that both maintain the time difference.
So the first flow would run in this fashion: 00, 30, 1:00, 1:30...
Second flow would run in this fashion 15, 45, 1:15, 1:45....
But the problem over here is when the broker gets restarted, both of them r starting at the same time. Basically the broker restart should not effect the timings.
How could we design this.
I would appreciate any suggestions/help.
Regards,
Kiran |

You want to change the flows.
You should, in the flow, calculate (maybe based on a user defined property) when the next interval should start.
For example, get the current time, and then calculate how long you need to delay until the first interval. Then stick a flag into a shared variable that says you can just wait 30 minutes the next time.
This can be done with TimeoutControl in addition to TimeoutNotification.

Thank You for the support
As Jefflowrey said, I had to use both the TimeoutControl and TimeOutNotification nodes. I had to compile the schedule time and send it to TimeOutControl, which would later trigger the TimeoutNotification node in a controlled fashion.
