HI,
I have a requirement to automatically (without any external trigger) run a message flow (MSG_FLOW1) at a specific time on Sunday to do some clean up activities in Database.
During the time MSG_FLOW1 is running , I need to stop my regular message flow (MSG_FLOW2) which has a TimeOutNotification Node and configured to runs in every 10 sec.
One way which which we could think about is introducing a time check in MSG_FLOW2 and if the time is nearing the clean up time , give an input to MSG_FLOW1 to start the clean up. Else do the regular activities of MSG_FLOW2. But since out MSG_FLOW2 is very complex having a conditional check in every 10 sec might not be a good approach.
Can you please help by suggesting a way to achieve this.
Thank You. |

Make better use of the system utilities designed for such: cron.
Don't turn WMB into a sys-admin tool. Use the sys-admin tools you already have.

| The timeout notification node can run automatically upon deployment or flow start. You can use that capability to automatically schedule your desired time of timeout (Sunday at X o'clock) for your main flow. Your main flow will need another timeout notification node that fires on schedule. The scheduled flow will need to stop your other (10 second interval flow), do it's processing, then start the 10 second interval flow up, and reschedule the next run. |

Thank you for responding to my query.
Can you please tell me how to achieve this-> The scheduled flow will need to stop your other (10 second interval flow)
How do we stop/start a message flow by getting control from another flow ? |

Controlling one flow from another has been discussed many times on this forum.
-- Job Control node support pack
-- Issue PCF commands to 'get inhibit' the input queue of a queue
-- Write some java to issue the mqsi... commands
I am sure there are many others.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |
