Working with Messaging Connection Aliases
A messaging connection alias defines the configuration needed to establish a connection between 56 and a webMethods messaging provider. You can use Universal Messaging and/or Broker as a webMethods messaging provider. For each messaging provider that you want to use, you need to create a messaging connection alias.
Although an Integration Server can only have one messaging connection alias that connects to a Broker, you can have multiple messaging connection aliases that connect to Universal Messaging servers.
You assign a messaging connection alias to publishable document types. Publishing services use the assigned messaging connection alias to publish instances of that document type to the messaging provider. webMethods messaging triggers use the messaging connection alias to retrieve published documents from the messaging provider.
