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.

With this solution a single DBA can be assigned control and management of database backup, restoration, and recovery.

Only infrequently does the history of IT occupy writers on the industry but Matthew Lasar's article "The Unix revolution -- thank you, Uncle Sam?" is an exemplary bit of IT history. Lasar backtracks to 1956 when AT&T and the U.S. Justice Department signed a consent decree that, among other things, prompted AT&T to begin licensing its formerly closely held Unix patents with the declared intention of not providing support for the code. Thus, Lasar argues, was born what we now know as "open source," though he concedes that not all will agree with his interpretation of events. In any case, the article is a rewarding read.
