I would be very surprised if they did... 18.104.22.168 was the terminal/FINAL release of 9i and as of now, they are not back-porting any new fixes or features. It is a dead horse - time to move on to something that is still alive (for now...) 10gR2 (.05) is going to be the terminal release of 10g (whenever it hits the streets.) [This has been stated in several TARS filed at my previous employer] So, if you want to actually have a SUPPORTable database engine, I suggest starting down the 11g path. There are a LOT of new features that will help with true high availability - to the point that you may never need to take a complete downtime for your [RAC cluster] again. (you can do true "rolling" upgrades - even to completely new versions - to each node individually and still have the "database" accessible at all times.) Received on Fri Apr 03 2009 - 22:02:53 CDT
