Brandl and Guschakowski Deliver Excellent CEP/BAM Report
Hans-Martin Brandl and David Guschakowski of the University of Applied Sciences Regensburg, Faculty of Information Technology/Mathematics, have delivered an excellent CEP thesis, Complex Event Processing in the context of Business Activity Monitoring, to their advisor Dr. Rainer v. Ammon. In their report they examined a BAM application using CEP concepts to implement what they referred to as [...]
Read moreEvent Transformation Services
In my last post, CEP Event Sources, I started a (short) list of event sources, both in theory and in practice, for complex event processing. There were some good comments and the list is evolving and improving. Event transformations are used to convert inbound event objects to an outbound object type required by a transport [...]
Read moreCEP Myopia
Those with myopia see nearby objects clearly but distant objects appear blurred. Nearsightedness tends to run in families and usually appears in the early stages of life. It is a vision problem experienced by up to about one-third of the population. Nearsighted people have difficulty seeing the full picture, but can see up-close applications. Myopia [...]

BEA has a nice screencast that demonstrates event processing in airport operations. Their screencast illustrates how WebLogic Event Server can be configured to detect missing events, a requirement often discussed in many CEP and ESP applications (not unique to BEA). The demo uses SL’s RTV, also used by TIBCO and Progress Apama, as a business [...]
Read moreBEA Publishes Event Server 2.0 Docs
BEA has made their WebLogic® Event Server 2.0 documents available in both HTML and PDF format to the general public. This is good news for everyone. Currently there are 6 PDF files: Getting Started With WebLogic Event Server Creating WebLogic Event Server Applications WebLogic Event Server Administration and Configuration Guide EPL Reference Guide WebLogic Event Server Reference [...]
Read moreBending CEP for Rules
I think James Taylor and my good friend Paul Vincent should be mindful not to reduce CEP (accidentally or intentionally) to rule-based systems, and broaden their perspectives and blog entries. In the original work on CEP by Dr. Luckham, the point of CEP is to solve complex problems in many problem domains, many require backwards [...]
Read moreCEP Soapbox: Moving from Marketing to Modelling
Many of the folks in the event processing community are my dear friends, so I hesitate to stand up on my vulnerable soapbox and speak a piece of my mind. If you would be so kind to permit me to get on my soapbox without naming names or providing links, that would be much appreciated. [...]
Read moreAn Event Cloud Generator for CEP Testing
Alexander Widder (Centrum für Informations-Technologie Transfer GmbH, Germany), and I have been discussing the need for an event cloud generator that could be used for generating CEP scenarios for testing and evaluation purposes. For example, integrating flat files from UNIX/Linux syslog generators (if one exists, need to check) with an open source ESB like Mule (from [...]
