Understanding Hub Routing Types
There are two hub routing types: generic routing and sender-specified routing. The configuration steps for a hub vary, depending on which routing type you choose.
With generic routing, all transactions from the participating systems are sent directly to a hub for routing and transformation.
With sender-specified routing, a destination node name is passed as a parameter to a PeopleCode Publish or SyncRequest method, such as %intBrokerPublish or %intBroker.SynchRequest, to explicitly route the outbound transactions to the necessary node. Using sender-specified routing requires that you define the explicit destination nodes on the sending system. However, you can configure the system so that PeopleSoft Integration Broker passes these outbound transactions to the hub for possible rerouting and transformation.
Note:
You must use sender-specific routing when you're using PublishXMLDoc to asynchronously publish an XML object.
Regardless of which hub routing you use, you must configure each PeopleSoft application's integration engine, the integration gateway, and the PeopleSoft Integration Broker hub. A PeopleSoft Integration Broker hub can be an installed PeopleSoft application, or it can have only a stand-alone PeopleTools database installed, which includes the integration engine.
