Oracle CEP Blog

Oracle Complex Event Processing 10g Release 3 (10.3) was released a few weeks ago (October 15, 2008).  This is the first new release of the rebranded WebLogic Event Server (WL EvS) product from BEA.  The Oracle CEP release  comes 15 months after the initial release of WL EvS.  It was a busy time, made even busier by the acquisition, but as always seems to have gone by way too fast.  The online documentation for Oracle CEP is available here.

The new features that the engineering team put in for this release include:

1. Data Grid support.  Distributed caching systems, like Oracle Coherence, are now integrated into the OCEP programming model.  This gives OCEP applications not only fast access to cached data, but also high availability (HA) for the data that they produce.  Oracle CEP 10.3 actually includes a Coherence OSGi bundle.
2. Clustering. The clustering support makes it possible to create a multi-server domain.  This is especially useful when deploying an applications that use a hot-hot architecture.
3. Event Record and Playback.  This feature allows events to be persisted and then played back later -- very useful for debugging or testing the effectiveness of new application logic.
4. Administration Console.  A new administration console -- also known as the "Visualizer".  The Visualizer allows administrators to manage and monitor OCEP applications.  The Visualizer was built using Adobe Flex.
5. Performance.  Lots of hardening work to make applications go really fast.  The performance guys never get enough credit for all the work they do.
6. And more.  The rest of the new features are listed on the documentation page.
