Oracle Service Bus is an enterprise service bus designed for connecting, mediating, and managing interactions between heterogeneous services. Oracle SB can handle Web services, Java, .Net, messaging services, and legacy end points. Oracle SB is designed to handle the deployment, management, and governance tasks required to implement SOA (Service Oriented Architecture) at any scale.
Oracle Service Bus is stateless and policy-driven. It enables you to establish loose coupling between service clients and business services while maintaining a centralized point of security control and monitoring.
Oracle BPM 10.3 only supports Oracle Service Bus 10.x (formerly AquaLogic Service Bus 3.0).
