b. If you chose the Selected Broker s option above, move your Brokers from the Available list box to the Selected list box.
c. In the Number of Broker s field, specify the number of guaranteed receiver Brokers in the cluster to which you want to send the messages. If the message is not delivered to the exact number of Brokers you specify here, the multi-send operation will fail.
