Hello,
is it possible to start and stop a message flow at certain time using timeout nodes? say every midnight?
I have a need to read all logged messages from log queues and write to a file every midnight. However, the timeout notification node can only be configured to run at defined interval from the time the broker is started.
An alternative would be to use a cron job to send a message at every midnight to start a flow to achieve the above, and then stop it, but haven't figured out how.
Has anyone done this or similar?
thanks for sharing your insight!

We are stopping some message flows by using an external application which uses CMP API. This application gets triggered by MQ messages which are sent by an application started with our scheduler.

The JOB control node support pack can also be programmed to do all sorts of nice things.
I use it to control FlowMonitoring where it is difficult to get command line access to the system.
Two simple CRON Jobs would also do the job.
One to start the flow at midnight and the other to (sometime later) stop it.
THere are many other solutions including using a second QMGR and holding all the messages on that until the desired time. Then starting the channel, thus releasing all the messages. Then waiting a minute or so and then stopping it.

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

Hi j.f.sorge and smdavies99,
thanks so much for sharing these!
I didn't know there are command to start and stop single messageflows. Then it becomes a trivial task to do what I need, and no need to use the timeout node.
