Oracle WebLogic Server 12.1.2, which is part of Oracle Cloud
Application Foundation, contains a number of exciting new capabilities, such as
support for RESTful services and HTML5 WebSockets. One of the features we’re most
excited about is what we call dynamic clusters. Dynamic clusters allow an
application to dynamically add servers on the fly. This used to have to be
manually preconfigured and now it’s automated, which offers a very elastic
environment for the applications we’ve been discussing. Also, Oracle WebLogic
Server 12.1.2 supports the new Oracle Database 12c release including its
multitenancy option, which is a significant capability for developing cloud
applications. Assuming that an application is providing software as a service [SaaS],
multitenancy means that each organization that’s purchasing that service has
its own secure set of data. Typically, it would be very expensive from an infrastructure
or management point of view to give each tenant its own database, but a true
multitenanted database capability is actually built into Oracle Database 12c.
Oracle WebLogic Server works very closely with the database to take advantage
of that capability, including taking advantage of what’s called Database
Resident Connection Pooling Purdy fuels up for the day with coffee and a
banana. IT’S COMPLICATED We need automation of management and simplification of
infrastructure and platform just to manage the complexity that is inherent [DRCP],
which is a serverside connection-pooling capability that significantly reduces
the number of physical connections necessary between a cluster of application
servers and a database cluster.
