Oracle Mediator and Oracle ESB

Oracle Mediator is a component of Oracle Fusion Middleware 11g. Oracle Mediator separates integration concerns from applications and business logic. It moves data among disparate applications, both within and outside of an enterprise. It provides a messaging infrastructure and uses open standards to connect, transform, and route business documents. Oracle Mediator cannot provide services. Instead, it virtualizes endpoints and mediates between a client and a provider of a service.

In Oracle releases earlier than 11g, Oracle Mediator was named Oracle Enterprise Service Bus (ESB)

PeopleSoft supports integrations Oracle Mediator and Oracle ESB-based services. From a PeopleSoft perspective, the main differences between Oracle Mediator and Oracle ESB are:

• Oracle Mediator supports asynchronous request/response integrations. You cannot perform asynchronous request/response integrations using Oracle ESB.

• PeopleSoft supports integrations with Oracle ESB nested WSDL documents. Note that Oracle Mediator does not support nested WSDL documents.
