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.

Monitoring progress


When your application is in production, one of the major tasks is to make sure that your applications are running as expected. You can verify this by monitoring the throughput and the latency of the events being processed by your applications.

In the Visualizer, first select the application and the stage that you wish to monitor in the Domain Browser window. For example, let's select helloworldAdapter. Next, click on the Create Diagnostics button, which is shown in the following screenshot:

When you do this, a new panel with three sections named Profile Information, Latency, and Throughput shows up. In the Profile Information section, you need to give your monitoring profile a name, and optionally set the State option to On. Keep in mind that a profile can monitor both latency and throughput. Next, we show how to monitor latency:

Next, select the Latency section. In this section, you can enable the monitoring of the latency of the events that flow through the EPN. The latency...
