WebLogic Server includes features that allow deployed applications to easily use Coherence data caches, and seamlessly incorporate Coherence*Web (not A) for session management and TopLink Grid (not C) as an object-to-relational persistence framework. Collectively, these features are referred to as ActiveCache.
ActiveCache is employed by applications running on WebLogic Server and provides replicated and distributed caching services that make an application's data available to all servers in a Coherence data cluster. New features in this release provide direct access by applications to data caches, either through resource injection or component-based JNDI lookup, and let you display, monitor, create, and configure Coherence clusters using the WebLogic Server Administration Console and WLST.
