Oracle Stream Analytics (OSA): the new Oracle Stream Explorer

A few days ago, Oracle released the new version of Oracle Stream Explorer and renamed it to Oracle Stream Analytics (OSA). This new version is an impressive release with over 15 new major features! It really deserves the name change.

Enhanced Patterns Library

The existing patterns have been enhanced substantially  now including Spatial, Statistical, General industry and Anomaly detection through streaming machine learning.

patterns

New Geo-spatial pattern

This pattern can be used to analyze streams containing geo-location data and determine how events relate to pre-defined geo-fences in your maps.

Integrated Expression Builder

The Expression Builder allows to add calculated/derived fields on the Live Output Stream of an exploration, an important step towards the “streaming Excel sheet” idea of Oracle Stream Analytics.

expression.png

It provides the ability to apply and insert mathematical and statistical calculations into the active live output stream. Once a new expression has been defined and validated, a column will be added next to the column of relevance. This new column can then be used in subsequent filters and explorations.

Support for Business Rules in Explorations

The Business Rules section of the Stream Analytics canvas provides the ability to apply the more traditional IF-THEN-ELSE constraints and clauses on the various properties of the event shape.

This capability enables the user to combine both streaming query analytics using temporal criteria together with a collection of business rules that can randomly effect the information in existing or new columns.

New streaming end point connections/targets

Oracle Stream Analytics supports new Event Stream sources and targets, such as MQTT, Apache Kafka and Twitter.

connection

Especially Kafka gets more and more important in modern Big Data architectures so I’m really pleased to see it available now.

We can now use Oracle GoldenGate for immediately capturing changes on any database table (CDC = change data capture), send these captured change events into Kafka using  GoldenGate for BigData  and consume it from OSA to apply streaming analytics on it.

Scaling-Out with Spark Streaming

An OEP server is no longer the only runtime option. With Oracle Stream Analytics you can deploy and execute streaming applications to a Spark Streaming infrastructure.

The figure below shows how you can select one of the two possible runtime environments (Spark grayed-out because not yet configured on my environment).

Better Insights with Catalog Topology Viewer and Navigation

Topology is a graphical representation of the connected entities. The topology illustrates the dependencies and connections between the entities. The Topology Viewer helps in identifying the dependencies that a selected entity has on other entities. Understanding the dependencies helps you in being cautious while deleting or undeploying an entity.

I’m really pleased with this new release and I’m looking forward to see more enhancements and improvements in future releases. As already mentioned, the product really deserves the name change, but I also hope it’s the last one for the next couple of years ;-). Oracle Stream Analytics simplifies stream processing and will enable Self Service Streaming Analytics applications for business people.

Find more information on Oracle Stream Analytics in the Documentation available here.

Stay tuned for an update on the Docker support I already had for Stream Explorer. I’m currently in the progress of updating it for Oracle Stream Analytics so you can quickly setup your own playground environment.

Our new book “Design Principles for Process-driven Architectures Using Oracle BPM and SOA Suite 12c” got published

DesignPrinciplesBPMandSOA

In the past year I have contributed to a new Packt book titled “Design Principles for Process-driven Architectures Using Oracle BPM and SOA Suite 12c”. I’m very happy that we have managed to publish it this June.

This book is a design handbook and provides skills to successfully design, implement, and optimize business processes on top of SOA. Starting with business process modeling, it shows design principles to architect sound process architectures. It presents best practices for modeling business processes using BPMN, together with design principles for services and composite applications. It provides detailed coverage of how to prepare business processes for execution. An in-depth explanation of human interactions is given and also principles and best practices for using rules.

Moving on, Adaptive Case Management principles are explained, along with the reach of business processes to mobile devices and ensuring multichannel interactions. Business activity monitoring, event-driven architectures, complex event processing in relation to business processes, and enabling integration with events and IoT devices are explained. The design principles and best practices are demonstrated in a practical way on a rental car use case.

You will learn

  • Design principles to model business processes and business architectures
  • Best practices to produce executable business processes in BPMN
  • Principles when designing reusable services and composite applications
  • Advanced approaches to human interactions in business processes, including patterns and Adaptive Case Management
  • Business rules management and principles for rule design and implementation, including using rules in BPMN and BPEL processes
  • Prepare process applications for mobile and multichannel/omnichannel
  • Explore the best practices and principles of Business Activity Monitoring to define and monitor Key Performance Indicators
  • Extend the processes to Internet of Things devices and processing complex events

Enjoy the reading! We hope you like it!

Installing Oracle SOA Suite 12c Quick Start Distribution

A week ago, Oracle released Oracle SOA Suite 12c. In this blog I will show how easy it is to create a SOA Suite development environment.

The Oracle SOA Suite 12c Quick Start distributions allow you to quickly install a development or evaluation environment on a single host computer. It only takes a couple of minutes to set it up.

Before starting the installation, make sure that you have a working Java Development Kit (JDK) environment.  At the moment Oracle Fusion Middleware products require JDK7.0 Update 55 or later.

Obtain the Product Distribution

Download the Oracle Event Processing from here.

Find the fmw_12.1.3.0.0_soaqs_Disk1_1of1.zip, download it onto your system and extract it.

Unable to change WS Policy Store to “App Server Connection” in JDeveloper

Today when trying different settings with Basic Authentication and SOA Suite, I wanted to from the embedded OWSM Policy Repository of JDeveloper to the one stored on the application server. In JDeveloper you can do that through preferences (Tools | Preferences). See this blog for more details.

Click on the App Server Connection option and choose an existing connection through the Connections drop-down or add a new one by clicking New.

Unfortunately the change was not saved after clicking OK and when returning to the screen the option was still set to File Store.

A restart of JDeveloper just before changing the option solved the issue!
