OSB Solution Set

Oracle Service Bus Internal Architecture The following diagram shows the internal architecture of the service bus with proxy services, business service points and endpoints. The proxy provides transparent views of the endpoint which allows for modifications to the proxy service without impacting the actual service endpoint. Each proxy interfaces with a business service that provides the logical view of many service endpoints. Each endpoint is a concrete implementation of service.

BPM Cluster Design and Deployment OSB enables management and coordination of numerous distributed endpoints to provide centralization in an enterprise. This facilitates the horizontal scaling of heterogeneous OSB hubs by clustering the underlying Web. Logic Server to create a distributed OSB network. The cluster includes a set of managed servers that handle message processing. There is one main administration server in every clustered domain and there can be only one OSB cluster per domain. A central deployment of the OSB will be used for governance and coordination and every OSB/ESB in the network will communicate through the central OSB. The central OSB will propagate configuration and metadata automatically to the managed servers. OSB enables reliable and guaranteed messaging through the federated network using JMS store and forward. The dynamic routing capability simplifies configuration of a federated network. By spreading the messaging load homogeneously over the clustered servers bottlenecks can be prevented. The figure below shows the flow of message data in an OSB cluster topology.

Oracle Web Services Manager (OWSM) is a component of Oracle SOA Suite that provides for local enforcement of security policies offering runtime SOA governance. OWSM is used for securing and monitoring activities performed on protected web services and facilitates security policy management with reporting capabilities. With OWSM, policies that govern Web Services operations can be centrally defined and applied to the services without having to modify them directly. Monitoring statistics can be collected for ensuring quality of service, uptime, security threats and more. The statistics can be displayed on a dashboard. Components of OWSM include: Policy enforcement points (PEP) – Used to manage and enforce the security of Web Services using gateways and client/server agents. The OWSM gateways are deployed on J 2 EE containers, acting as a proxy to the Web Services Client. The client agent intercepts requests from Web Service clients and enforces policies for encryption and signatures. The server agent enforces authentication and authorization. OWSM Policy Manager - a component that is installed on J 2 EE containers and used for Web Service Registration, Policy Configuration and Policy Communication. OWSM Monitor – contains two components (Collector and Aggregator). The monitor manages the collection and aggregation of data for monitoring Web Services Traffic. OWSM Control – Web based control to administer OWSM components. OWSM Database – Used to store policy data, monitoring data and system configuration.
