Some very good points made by Vladimir nicely organized and summarized.
So many companies are driven by buying applications from others and running them against "certified" vendor releases. So you "cannot" get support from your application vendor unless you are running against specific oracle releases. That does change, over time, gradually ... depending on the app vendor and as Vladimir noted the dependencies in pieces of the applications and tools/technologies they were developed with.
If your applications are custom aka "roll your own" and supported in house then well there's nothing much from stopping you from evaluating getting current with oracle technologies. As long as you are paying for support ( not all places are ) then the upgrades in database versions are no additional charge.
We are rolling along with some 10.2.0.4 and some 11.1 probably will be 11.2 on some systems soon. Received on Thu Aug 28 2008 - 18:33:38 CDT
