6.11. Cancelling the distributed infobase master node assignment
To cancel assignment of the distributed infobase master node, use the /ResetMasterNode command in Designer batch mode command line. This operation is equivalent to calling the SetMasterNode(Undefined) method of the ExchangePlansManager object.
This may be necessary, for example, when you need to separate a subtree of the distributed infobase into an independent infobase or to reassign a distributed infobase node.
