You can configure the webMethods Broker to distribute messages to multiple consumers in the same order in which the webMethods Broker received the messages. To do this, when creating destinations in Designer, set the Order By property to Publisher. When using the Broker interface in My webMethods to create destinations (queue or durable subscriber), set the Shared State property to “publisher”.

When a destination has a shared state order of publisher, the webMethods Broker distributes messages to consumers in a serial fashion. This occurs even if multiple load-balanced consumers share the same destination. For example, suppose that Server1 and Server2 request messages from QueueA on behalf of JMS triggers. The webMethods Broker gives Server1 the first message in the queue. The request from Server2 for a message is blocked until Server1 acknowledges the message. Server2 then receives the next message.
