I have a message flow that performs DB table maintenance (the tables are used by the message broker for lookup & txn logging). This message flow needs to be activated at a certain time of the day, i.e. 10:00 p.m. every night.
The message flow can be developed in such away that it is started/triggered via an input node. For this, it means that i need to have an application that puts a message into the input queue at 10:00 p.m. everynight.
I'm looking for another method which do not need interaction from other application (i.e. self-contained within the message broker). One way which i can think of is a time trigger node.
i'm using WBIMB V5.0 at present. The timer node which i heard of is available only on V6.0.
Does anyone know of any other method to implement the "time-triggered" message flow?
Thanks. |

You can implement this by either way.
1. Write a customed 'Time Trigger Node'
or
2. Implement this in MQ level. for an example store all the message in a queue,associate this with a system scheduler application which can be invoked at certain time and receives all the meassage and puts them ina request queue. The flow picks the message from request queue and does the processing...

Do you mean, trigger an application, make it put request messages into the flow ?

Yes there are certain system schuduler application which is

| triggered by operating system not by MQ at a desired time |
. You can mention there your input queue name as well as request queue name.
I have no practical experience regarding this. But in our projects same kind of design was implemented in Netherland and Belgium.
Please search for such types of application.
I am affraid...  no much help from me in practical scenario.

What your talking about are schedular run programs on Windows or cron jobs on AIX etc...The programs can be any Java, C etc programs, and these can pick from queue...But for careboy it would make no sense in picking messages and then running the flows when what he really wants is just time triggers...
careboy:
You can make a custom Trigger node as sourdas2 suggested...or the easier way out, run a scheduled app to run the flow...
