Understanding Oracle Service Bus: A Comprehensive Guide

Oracle Service Bus (OSB) is a powerful product from Oracle that enables economical system integration with the common standards most enterprises use. It is an architecture based on the Enterprise Service Bus, designed to communicate between applications. OSB provides message delivery based on standards including SOAP, HTTP, and Java Messaging Service (JMS). It is a scalable and reliable option that can be used to set up a new service quickly. OSB has a proxy service that contains the message processing logic for handling requests and optional response messages. It also provides an interface that the service consumer calls.

Oracle Service Bus (OSB) is a design based on the Enterprise Service Bus

Oracle Service Bus (OSB) is an architecture based on the Enterprise Service Bus. It is designed to facilitate communication between applications within an organisation and their connected enterprises. OSB provides message delivery based on common standards such as SOAP, HTTP, and Java Messaging Service (JMS). This allows for communication with almost any system and enables legacy systems to communicate with new systems.

One of the key capabilities of OSB is enabling system agility. By supporting popular standards, OSB offers IT departments flexibility in strategy selection. Additionally, OSB is designed to be scalable and reliable. When setting up a new service, OSB facilitates rapid service enablement and supports open standards for easy integration with other vendors.

OSB has several key components that contribute to its functionality. It includes a proxy service that handles message processing logic for requests and optional response messages. It also provides an interface for the service consumer to interact with. OSB features a business service that integrates external systems, simplifying the implementation process for development teams. Service virtualization enhances agility by replacing direct coupling and providing a virtual endpoint for the consumer. This also enables benefits such as supporting different messaging formats, service versioning, and enhanced security.

OSB's Message Transformation capability allows for different message formats for inbound and outbound messages. With XQuery or XSLT, messages can be transformed quickly and efficiently. Dynamic Routing enables messages to be routed to services that may not be known at the time of development. Additionally, OSB is fault-tolerant and can handle system interruptions when Service-Pooling is configured.

OSB provides message delivery based on standards including SOAP, HTTP and Java Messaging Service (JMS)

Oracle Service Bus (OSB) is an architecture based on the Enterprise Service Bus (ESB) that enables economical system integration with the common standards most enterprises use. It provides message delivery based on standards including SOAP, HTTP, and Java Messaging Service (JMS).

SOAP (Simple Object Access Protocol) is a messaging protocol specification for exchanging structured information in the implementation of web services in computer networks. HTTP (Hypertext Transfer Protocol) is an application layer protocol that enables communication via the World Wide Web. Java Messaging Service (JMS) is a messaging standard that enables communication between software components that are based on the Java Programming Language.

By supporting these protocols, OSB can communicate with almost every system out there. It allows legacy systems to communicate with new systems and can bridge the gap with older systems such as a mainframe, allowing them to remain in service.

OSB provides a great way for enterprise Information Technology departments to foster communication. It is designed to act as a mediation, integration, and interface layer. It supports many popular standards, offering IT departments flexibility in choosing their strategies.

OSB is a scalable and reliable option. When setting up a new service, OSB facilitates rapid service enablement. It also supports open standards that help integrate with other vendors.

OSB has a proxy service that contains the message processing logic for handling requests and responses

The proxy service defines the interfaces in terms of Web Services Description Language (WSDL) or Web Application Definition Language (WADL) and the type of transport used. A proxy service can have one of the following service types, identified by the types of messages it processes:

• WSDL Based Service
• Messaging Service
• Any SOAP Service
• Any XML Service (non-SOAP)
• REST Service

A proxy service can be generated from an existing WSDL and WADL document, or it can be created using the Service Bus Overview Editor in JDeveloper. The Create Proxy Service wizard provides a series of pages where specific proxy service properties can be configured.

The available transport protocols for a proxy service vary depending on the service type. Each transport protocol has its own configuration requirements. The properties that can be configured here include the endpoint URI, whether to retrieve all or a subset of headers, and the transport detail settings.

Once a proxy service is created, it can be configured to check messages for WS-I compliance, set up SLA alert rules, and secure the service through multiple methods including Oracle Web Services Manager (OWSM) policies and access control at the transport and message levels.

OSB is policy-driven, configured and designed for enterprise service with SOA life cycle management

The Oracle Service Bus (OSB) is an architecture based on the Enterprise Service Bus (ESB). It is a configuration-based, policy-driven enterprise service bus designed for SOA life cycle management. It provides a foundation for service discovery and intermediation, rapid service provisioning and deployment, and governance.

OSB is policy-driven and designed for enterprise service with SOA life cycle management. It adheres to the SOA principles of building coarse-grained, loosely coupled, and standards-based services. These services create a neutral container in which business functions can connect service consumers and back-end business services, regardless of the underlying infrastructure.

OSB is also designed to act as a mediation, integration, and interface layer. It allows communication over popular protocols such as SOAP and Rest, enabling it to communicate with almost every system. This capability makes OSB ideal for bridging the gap between legacy systems and new systems, allowing older systems to remain in service.

The policy-driven nature of OSB is further evident in its support for various security standards and frameworks, including Oracle Platform Security Services (OPSS) and Oracle Web Services Manager (OWSM). OSB provides authentication, encryption, decryption, digital signatures, and SSL to ensure secure communication between services.

Additionally, OSB offers a scalable and reliable option for enterprise integration. It enables economical system integration by supporting common standards used by enterprises. The clustering feature of OSB provides high availability, making it a desirable choice for organizations.

OSB supports open standards that help integrate with other vendors

The Oracle Service Bus (OSB) is a design based on the Enterprise Service Bus. It provides economical system integration with the common standards most enterprises use. OSB supports open standards that help integrate with other vendors.

OSB provides message delivery based on standards including SOAP, HTTP, and Java Messaging Service (JMS). It provides a great way for enterprise Information Technology departments to foster communication. By allowing communication over popular protocols such as SOAP and Rest, it talks to almost every system out there. Many companies have used OSB to let legacy systems communicate with new systems. It can bridge the gap with older systems such as a mainframe and allow them to remain in service.

A key capability of Oracle Service Bus is enabling system agility. By supporting many popular standards, OSB can offer your IT department flexibility in choosing its strategies. Oracle also knows how to design systems that are scalable and the Oracle Service Bus is no exception—it is a scalable and reliable option. When you need to set up a new service, Oracle Service Bus will facilitate rapid service enablement.

Oracle Retail Integration Bus (RIB) Essentials should not be confused with Oracle Service Bus (OSB). ESB was developed by Oracle. OSB, formerly known as Aqualogic Service Bus, was acquired when Oracle bought BEA Systems. The two products are related and interchangeable.
