Recently I attended a half-day 11g launch locally in Vancouver where the local Oracle office invited a couple of Oracle Directors from San Francisco to talk about 11g. Obviously there are too many 11g features to talk about so a few were highlighted and it dawned on me that a number of these highlighted features requires additional licenses on top of the usual RDBMS Enterprise Edition. A way to get more revenue for Oracle?
Do you know what components/add-ons/options are licensable?
Fortunately Oracle Corporate site does provide a list ( it is not comphensive or exhaustive) but it's a start and a more complete list is available here. I know that Mark Brinsmead of Pythian had blogged about another component that is not on the list, namely the AWR. The AWR is actually part of the Oracle Diagnostics Pack.
