WebLogic section: Configure Coherence HotCache by Edwin Biemond

Coherence can really accelerate and improve your application because it's fast, high available, easy to setup and it's scalable. But when you even use it together with the JCache framework of Java 8 or the new Coherence Adapter in Oracle SOA Suite and OSB 12c it will even be more easier to use Coherence as your main HA Cache.

Before Coherence 12.1.2 when you want to use Coherence together with JPA for the database connectivity, you must make sure that there is no batch job or application doing modifications directly in the database. This will lead to an out of sync Coherence Cache. But with Coherence 12.1.2 together with GoldenGate you can capture these database changes and send updates to the Coherence Cache. This is called Coherence HotCache. Here you can see how it basically works. Read the complete article here.
