Hi,
I am trying to use AMiT Situation Node, in a Message flow. Message flow is deployed on Brokers that are on cluster, So that the events are distributed to multiple brokers. Since the events are distributed the Situation Manager is not detecting the situations properly (Not all situations are caputred).
I have also enabled persistency on the Situation Manager Node.
Can some one help me in this??
It will be too bad if AMiT Node are not supported for clustering scenario. 
Thanks
Mohan |

I don't believe that the runtime for CEP currently supports what you're trying to do - in the way you are trying to do it.

Sure.
Put the Situation Node in one flow on one broker, started from an MQInput.
Share the input queue in the cluster.
You'll also have to, unfortunately, put any flows that use the IntelligentFilter node into the same Broker.
I heard Guy Sharon talk about future plans to address this, about a year ago. You could also contact him - he's the author - and see what the status of those plans are.

I suspect that the real difficult part of this problem to solve is not "how to get all events to every broker" (that's just pub/sub) but "how to decide which broker should raise a detected situation".
You wouldn't want all of your brokers to raise the same situation every time, would you?
