Oracle Fusion Middleware 11g

Abhishek Khanolkar

What is Oracle Fusion?

• “Oracle Fusion Middleware is a ‘preintegrated’ portfolio of customer-proven software that spans from portals and process managers to application infrastructure, developer tools, and business intelligence”.

• In short it is a complete stack of related middleware technologies.

Components of Fusion

• There are about 17 different components.

• In this activity I worked with SOA Suite.

• SOA suite has the Oracle AS (Application Server), ESB, business rule engine, Oracle BPEL Process Manager, Oracle Web Service Manager.

Enterprise Computing.

• Enterprise computing means computing in the GRID environment or where applications run on many servers.

• Enterprise Computing is made possible by the use of middleware technology.

• Middleware's such as Oracle Fusion, BEA, IBM MQ and Tibco.

Technologies in Fusion:

• EJB (Enterprise Java beans).

• Types of EJB

• MDB (Message Driven Bean), Entity Bean and Session bean.

• JMS (Java Messaging Service).

• Web Service (most import part)

Importance of EJB

• EJB brings about the asynchronous communication.

• It automate the transaction management and reduce the code size.

• Provides security.

• Provides the remote access using the RMI and CORBA.

Web Services

• Web Service bring about the application to application interaction.

• It has a receiver and sender of SOAP messages.

• SOAP is a platform neutral XML based protocol

• Web Service send SOAP message that are then used by the applcations.

JMS

• JMS or Java Messaging Service is a standard messaging system.

• JMS has 2 messaging models- the queue based model and topic based model.

• The SOAP messages in the web Service are sent over JMS destinations (queue or topic).
