Additional SOA Patterns –Supporting Composition Controllers - Applied SOA Patterns on the Oracle Platform - page 578

ellery online with a peculiar delivery address, then someone should flag the card
with a possible fraud case and contact the card holder. This is the simplest ex-
ample that we can provide. When it comes to money laundering tracking cases in
our borderless world—the decision-parsing tree from the very first figure in this
chapter—based on all possible correlated events will require all the pages of this
book, and you will need a strong magnifying glass to read it; the stratagem of the
web nodes and links would drive even the most worldly wise spider crazy.
For these mentioned use cases, Oracle EPN is simply compulsory with some spice, like
Coherence for cache management and adequate hardware. It would be prudent to avoid
implementing homebrewed solutions (without dozens of years of relevant experience),
and following the SOA design patterns is essential.
Let's now assemble all that we discussed in the preceding paragraphs in one final figure.
Installation routines will not give you any trouble; just install OEPE 3.5, download it, in-
stall CEP components for Eclipse, and you are done with the client/dev environment. The
installation of the server should not pose many difficulties either ( http://docs.oracle.com/
cd/E28280_01/doc.1111/e14476/install.htm#CEPGS472 ) . When the server is up and run-
ning, you can register it in Eclipse (1) . The graphical interface will support you in assem-
bling event-handling applications from adapters, processor channels, and event beans;
however, knowledge of the internal organization of an XML config and application as-
sembly files (as demonstrated in the earlier code snippets) is always beneficial.
In addition to the Eclipse development environment, you have the CEP server web con-
sole (visualizer) with almost identical functionalities, which gives you a quick hand with
practically all CQL constructs (2) .
