Oracle realization of the Service Bus is based on the Business Service / Proxy Service concept, where every service is treated individually. That's what you will learn in every book dedicated to OSB (such as Oracle Service Bus 11g Development Cookbook, Guido Schmutz and Mischa Kölliker, Packt Publishing). This kind of personal-touch approach for every service has a strong reason as we would like to maintain the highest performance possible and desirable level of modularity. Only one more or less complex pattern (refer to the second figure in the Implementing a basic proxy on OSB section) is really provided out of the box in OSB: Split-Join. Using this pattern, we can split a really big message that has clearly distinctive separate parts (such as order line in a big order), do the parallel calls to order the line processor, gather responses in a join phase, and deliver the processed payload.

You have to implement all other SOA patterns yourself, just like we have covered in this chapter...
