Introduction and Roadmap

This section describes the contents and organization of this guide—Oracle Complex Event Processing Application Development Guide.

Document Scope and Audience

This document is a resource for software developers who develop event driven real-time applications. It also contains information that is useful for business analysts and system architects who are evaluating Oracle CEP or considering the use of Oracle CEP for a particular application.

The topics in this document are relevant during the design, development, configuration, deployment, and performance tuning phases of event driven applications. The document also includes topics that are useful in solving application problems that are discovered during test and pre-production phases of a project.

It is assumed that the reader is familiar with the Java programming language and Spring.

Oracle CEP Documentation Set

This document is part of a larger Oracle CEP documentation set that covers a comprehensive list of topics. The full documentation set includes the following documents:

Guide to This Document

This chapter, Introduction and Roadmap, introduces the organization of this guide and the Oracle CEP documentation set and samples.
Overview of Creating Oracle Complex Event Processing Applications, describes at a high-level the programming model used to create Oracle CEP applications. It provides a procedure that lists the typical steps a programmer goes through to create an application.
Creating Custom Adapters and Event Beans, describes how to create and configure the adapter components of an Oracle CEP application.
Using the Java Message Service (JMS) Adapters, describes how to use the built-in JMS adapter.
Using and Creating HTTP Publish-Subscribe Adapters, describes how to use the built-in HTTP publish-subscribe adapters, as well as create your own custom adapter.
Configuring the Stream Component, describes how to optionally configure the stream components of an Oracle CEP.
Configuring the Complex Event Processor, describes how to configure the complex event processor component of an Oracle CEP application.
Programming the Business Logic Component, describes how to program the business logic POJO component of an Oracle CEP application.
Using Oracle CEP Caching, describes how to use the event caching feature to increase the performance of your applications.
Storing Events in a Persistent Store, describes how to record events to a physical store, and then later play them back.
Assembling and Deploying Oracle Complex Event Processing Applications, describes how to assemble all the components of an application into a deployable bundle, and then how to deploy the bundle to Oracle CEP. After you have deployed the application you can start executing it.
Using the Load Generator to Test Your Application, provides detailed information for using the load generator, an Oracle CEP testing tool.
Additional Information about Spring and OSGi, provides links to additional non-Oracle information about Spring and OSGI.

Samples for the Oracle CEP Application Developer

In addition to this document, Oracle provides a variety of code samples for Oracle CEP application developers. The examples illustrate Oracle CEP in action, and provide practical instructions on how to perform key development tasks.

Oracle recommends that you run some or all of the examples before programming and configuring your own event driven application.

Pre-packaged and compiled in their own domain so you can immediately run them after you install the product.
Separately in a Java source directory so you can see a typical development environment setup.

The following three examples are provided in both their own domain and as Java source in this release of Oracle CEP:

HelloWorld—Example that shows the basic elements of an Oracle CEP application. See Hello World Example for additional information.

The HelloWorld domain is located in WLEVS_HOME\samples\domains\helloworld_domain, where WLEVS_HOME refers to the top-level Oracle CEP directory, such as c:\beahome\wlevs30.

The HelloWorld Java source code is located in WLEVS_HOME\samples\source\applications\helloworld.

ForeignExchange (FX)—Example that includes multiple adapters, streams, and complex event processor with a variety of EPL rules, all packaged in the same Oracle CEP application. See Foreign Exchange (FX) Example for additional information.

The ForeignExchange domain is located in WLEVS_HOME\samples\domains\fx_domain, where WLEVS_HOME refers to the top-level Oracle CEP directory, such as c:\beahome\wlevs30.

The ForeignExchange Java source code is located in WLEVS_HOME\samples\source\applications\fx.

Signal Generation—Example that receives simulated market data and verifies if the price of a security has fluctuated more than two percent, and then detects if there is a trend occurring by keeping track of successive stock prices for a particular symbol.See Signal Generation Example for additional information.

The Signal Generation domain is located in WLEVS_HOME\samples\domains\signalgeneration_domain, where WLEVS_HOME refers to the top-level Oracle CEP directory, such as c:\beahome\wlevs30.

The Signal Generation Java source code is located in WLEVS_HOME\samples\source\applications\signalgeneration.
