Forcing cluster traffic to a single node

Hi there,

I have a GetTCP processor running on both members of my cluster. I want to
force data received by both to a processor running on a single node. At the
moment, if I set that processor to run on only the primary, the queue from
the GetTCP processor on the secondary node just fills up.

Regards,
Phil

Thanks Mark, that’s working a treat - I must have tried every other
combination!

Phil,

You can configure the connection between GetTCP and the next processor to have a Load Balancing Strategy of “Single Node.” Then run the next processor on all nodes, not primary node, because it may not be the primary node that receives the data.
