Oracle Enterprise Service Bus is a component of Oracle SOA Suite providing the Enterprise Service Bus functionality. It builds the foundation for services using SOA. At its core, it is a loosely coupled application framework that provides business applications with increased flexibility, reusability, and overall responsiveness in a distributed, heterogeneous, message-oriented environment using industry standards.

ESB services are designed and configured with Oracle JDeveloper and Oracle ESB Control user interfaces. The ESB project which contains the services is registered to the ESB Server. The ESB Server supports multiple protocol bindings including HTTP/SOAP, JMS, JCA, WSIF, and Java that ensure guaranteed, reliable message delivery using synchronous/asynchronous, request/reply or publish/subscribe models. The ESB Server provides simple yet flexible deployment patterns to achieve high availability and scalability. Oracle ESB is one of the most performant ESB on the market today.

Currently, the ESB Server does not support Remote Method Invocation (RMI).
