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 moreClouds (Partially Order Sets) – Streams (Linearly Ordered Sets) – Part 2
Originally posted in Yahoo! CEP-Interest Here is my follow-up note on posets (partially ordered sets) and tosets (totally or linearly ordered sets) as background set theory for event processing, and in particular CEP and ESP. In my last note, we discussed posets and tosets in the context of ESP (tosets) and CEP (posets) and we [...]
Read moreClouds (Partially Order Sets) – Streams (Linearly Ordered Sets) – Part 1
Originally posted in Yahoo! CEP-Interest We read interesting discussions in the CEP and ESP market regarding terms like “clouds” and “streams”. Sometimes we observe folks talking about these terms in context of “processing time”, for example, reordering events as part of computational event processing. A closer examination of posets and linearly ordered sets leads to [...]
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 [...]
Read moreCEP with 40 Gigabits Per Second ?
In the early 90′s while consulting at Sprint, I worked with Peter Lothberg, who is, without a doubt, one of the world’s top networking experts. I remember Peter as a super-genius who debugged Cisco router software live on the major Internet routing exchanges back then. Those days were quite controversial (and political), and some of the [...]
Read moreGetting Started in CEP: How to Build an Event Processing Application (Part 1)
Complex event processing (CEP) is a promising new technology that aims to enable businesses to quickly identify and respond to both threats and opportunities. Many companies are interested in the promise of CEP but they are unsure where to begin. We are fortunate that our friends at Gartner are hosting their first event processing summit, [...]
Read moreMaking the Complex Simple with CEP
Many agree that the one of the most important aspects of complex event processing is making the power and flexibility of CEP analytics readily accessible to non-programmers. This important cornerstone of CEP is discussed in this excellent GCN article, Stream of Consciousness, mentioning StreamBase, Coral8, Progress Apama, and a new vendor in the CEP field, Truviso. [...]
Read moreInformationSecurityAsia2007 – Roundup
InformationSecurityAsia2007 was good, but could have been better. Most of the participants enjoyed the sessions on extrusion detection, indepth root kit analysis, and wireless hacking. There were also excellent presentations on the new Thai cybercrime law which goes into effect next week, as well as very good reports on cybercrime from Thai cybercrime fighting authorities. [...]
