The Oracle GlassFish Server is Oracle's commercially supported GlassFish Server distribution and constitutes a suite of features that improve performance, allow automatic backup of configuration and application data, enable fine-grained monitoring, and enable more secure and highly available production deployments. Customers also get 24 x 7 support, priority for their bug fixes and patches/hot fixes for them.

Blogger Sam Drake takes a look at how one might simultaneously exploit the fast memory-centric performance of TimesTen, and the large capacity and familiarity of the Oracle Database. He suggests using IMDB Database Cache (TimesTen) on the application server configured to cache tables from the Oracle Database. Thus, changes made by the application in TimesTen are automatically reflected in the Oracle Database. When a user logs off, data stored in TimesTen is erased, freeing RAM space for the next user, Drake writes, leaving the bulk of the database workload of your site handled in RAM, by the TimesTen database.
