Review of Introduction to Oracle Event Processing – chapters 10 & 11

The penultimate chapters don’t dive into the core Event Processing technology but look at some uses cases and the combination of CEP with Oracle’s spatial extensions and database capabilities. My initial reaction was that these chapters are perhaps more niche than I’d want, but when I thought a little longer it occurred to me that a lot of CEP use cases would include make use of spatial. Intact a system development I lead some years ago, if built today could be built using these features.

The book focuses on the idea of notifying people about a public transport service, but think about the great many mobile services evolving for smart phones given their push notification capability now you can see how e spatial features could offer a lot of value.

The chapters like everything else in this book are very well written, and worth reading.

If anything the questions left in my mind, are more commercial dimensions of such a technology – enterprise Oracle database which contains a number of the special feature is not cheap, and I’d imagine that the spatial cartridge isn’t cheap. This leads me to a natural next question, given the common application scenarios like e one described, has anyone stood up a SaaS service using this technology, and how cost effective/competitive/attractive would it be?

As you can see a thought provoking book.

Introduction to Oracle Event Processing – Chapters 6-9

book, CEP, event, Oracl, review

Continuing to look at the Introduction to Oracle Event Processing book, by chapter 6 the books has covered the key principles and ideas for building a CEP solution, and we’re now need to consider deployment. But refreshingly the book also takes on a number of non functional requirement (NFR) areas such as the issue of monitoring, a subject area that many technical books tend to ignore. The attention to monitoring is admittedly driven by the fact that Event Processing is inherently sensitive to timing and system loading etc and will obviously have a direct impact on what outcomes are produced.

As the book takes you through aspects of building a simple solution – the CEP equivalent to writing ‘Hello World’ it would be great if the authors could make the implementation available for download, so you could go straight into deployment.

Chapter 7, then takes us into other performance improving aspects such as how to get event enrichment data, and importantly exploit caching to drive the performance. If you’re familiar with Coherence then this aspect should be pretty easy to get to grips with, and the book actually focuses on the OEP aspects of the setup. If you don’t know Coherence, you’d do well to look at additional sources of information.

Chapter 9 is a natural evolution of 8 as further develops performance thinking with clustering and with it High Availability dimensions.

Before looking at High Availability (HA) and scaling the book drives back into more advanced scenarios with CQL by introducing Java into the syntax.

Introduction to Oracle Event Processing – Chapter 2

book, CEP, Event Processing, Oracle, Packt, review

Chapter 2 of the Getting Started with Oracle Event Processing book is really two smaller chapters introducing the platform in terms of its history, building blocks and the challenges that have had to be solved in the creation of an event processing platform (such as managing the potential impact of the garbage collector when handling very high event rates).

Not many books go into the underlying details of how a product is created, but in doing so the authors have provided a lot insight into the art of the possible and avenues for developing further understanding.

The second half of the chapter walks through the use of a demo scenario. Rather than providing details from standard Oracle manuals in a click by click type of guide, the book uses the example to show a flavour of breadth and depth of the tool.

This chapter doesn’t try to describe the installation process, but points you to the Oracle documentation and explains what it should guide you through.

Even if you don’t intend to exercise the demo, it is well worth reading the chapter to understand the construction and breadth of the tool. Based on what has been shown here, I believe some of the Oracle products such as AIA tooling could learn from it.

Chapter 1 of introduction to Event Processing

book, CEP, Event Processing, Oracle, Packt, review

Although the book’s introduction says that its target audience is developers and architects the first chapter is a very good introduction to the ideas and goals of Complex Event Processing (CEP) for anyone in the IT industry. The chapter explains the ideas and goals of CEP  illustrating them with easy to grasp real examples.

Possibly one if the best starts to a Packt book I’ve seen.

If your going to get stuck in with the more practical pieces then I’d start downloading the tools from Oracle as early as possible as there is several GBs of software. You might also consider cheating by downloading a prebuilt VirtualBox with the majority of the software already installed and configured.

Event Processing (CEP) – overview from EBizQ

CEP, EBizQ, event

The Enterprise Business IT blog/online journal have posted a number of articles and webinars looking at Complex Event Processing (CEP), Event Driven Architecture and related areas, the links are :

  • What is Event Processing?:Blogs and Resources
  • What is Event Processing?: Event-Driven Architecture
  • What is Event Processing?: Related Technologies
  • What is Event Processing?: Trends and Commentary

The EBizQ pages link to material by influential thinkers/analysts in the area such as Roy Schultze (Gartner) and one of IBM’s Lead Architect’s Opher Etzion.  If you’re looking for a basic handle on Event Processing particularly within the context of more mainstream business i.e. SOA (Service Orientated Architecture), BPM (Business Process Management), BAM (Business Activity Monitoring) issues then these links make a good starting point although although the this certainly doesn’t tell the whole story as it doesn’t address the super high volume players such as Streambase and the likes of my employer SeeWhy where we provide Event Driven BI (Business Intelligence) which has a natural affinity to BAM. However EBizQ does touch upon Event Driven BI here.

NB – I’m expressing my personal views rather than those of SeeWhy here.

The Killer App for CEP

app, CEP, Complex Event Processing

The online journal ebizQ are providing a webinar on ‘BAM:The Killer App for CEP’. Although SeeWhy would suggest that this is not exclusively the domain of Complex Event Processing, but any tool around Event Processing with a real-time capacity.  It would seem that SeeWhy is not the only organisation that sees how BAM (Business Activity Monitoring) is a natural partner for Event Processing as SeeWhy has produced an extension to its real-time Business Intelligence platform called ‘SeeWhy for JBoss jBPM’.

The webinar is sponsored by SL who provide a real-time style dashboard so will give some basic visibility of business activity, but doesn’t have the richness of SeeWhy’s intelligence or ability to feedback into the source system such as jBPM or event a third party.
