Hi,
I need to trigger a message flow at some predetermined time intervals. I've heard about the timer node in WMB. Please could someone tell me more. Also, are there any disadvantages using this?
Is there any other way of achieving this.
Thanks,
team |

This may be applicable in the other circumstance as well. I'm just not drinking enough...

Hi,
I need to take the details of the timing from a DB.
For example,
If the timing if time_trigger field of a table is 't'-mins, then a particular flow-X shud get triggered. Similarly if the time_trigger value is 't1'-mins, then another flow Y shud get triggered.
How can this be achieved using the timer node.
Thanks in advance,
Team |

In both cases, you need to compute the actual time (and maybe date) you want the flow to run and send a control message to a TimeoutControl (TC) node.
The DW papers and the Infocenter give the details about constructing the control message and how to send it to a TC node.
The flow is started by a TimeoutNotificiation (TN) node, which is associated with a TC node. If you want to start "different" flows, then you would have different TN nodes, which are controlled by separate TC nodes ....
