Overview of this book

Events are everywhere, events which can have positive or negative impacts on our lives and important business decisions. These events can impact a company's success, failure, and profitability. Technology now allows people from all walks of life to create Event Driven applications that will immediately and completely respond to the events that affect you and your business. So you are much more responsive to your customers, and competitive threats, and can take advantage of transient time sensitive situations. "Getting Started with Oracle Event Processing" will let you benefit from the skills and years of experience from the original pioneers who were the driving force behind this immensely flexible, complete, and award winning Event Stream Processing technology. It provides all of the information needed to rapidly deliver and understand Event Driven Architecture (EDA) Applications. These can then be executed on the comprehensive and powerful integral Java Event Server platform which utilizes the hardware and operating system.After an introduction into the benefits and uses of Event Stream Processing, this book uses tutorials and practical examples to teach you how to create valuable and rewarding Event Driven foundational applications. First you will learn how to solve Event Stream Processing problems, followed by the fundamentals of building an Oracle Event processing application in a step by step fashion. Exciting and unique topics are then covered: application construction, the powerful capabilities of the Oracle Event Processing language, CQL, monitoring and managing these applications, and the fascinating domain of real-time Geospatial Movement Analysis. Getting Started with Oracle Event Processing will provide a unique perspective on product creation, evolution and a solid understanding on how to effectively use the product.

Platform adapters


The platform adapters are out-of-the-box adapters, which you can use to receive data and create events without having to write your own Java code. They provide you with technical implementations of specific protocols while still giving you the flexibility to convert data as you wish, if necessary.

The JMS adapter

One of the most common ways to receive and send events into your OEP application is to set up a JMS adapter. OEP does not have the JMS server capabilities, but it does have all of the WebLogic JMS client libraries readily available for use.

The JMS adapter will create events from JMS map messages when you specify the name of the event that you would like to create. It will look for names in the JMS map message that correspond exactly to attribute names in your event type and map the values accordingly. Likewise, in the case of an outbound JMS adapter, it will take the attributes for the event that you specify and create a JMS map message that has a set of names and...
