How Does the Multisend Guaranteed Policy Work?

When you define a multisend guaranteed policy in a cluster, the webMethods API for JMS publishes a message to m out of n Brokers in a cluster by using XA transactions. Each Broker in the cluster acts as an individual XA resource and the publish operation is considered to be successful if the message is received by m out of n Brokers in the cluster.

Note:
Multisend guaranteed policy works only with XA connection type.
