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).
