Just thought I'd throw this out there since I haven't seen it mentioned, but Oracle is now doing "PSU" quarterly updates which are also inclusive and in addition to the quarterly CPU patch. So now I have a 10.2.0.4.1 environment :) ml 854428.1 http://www.ora-solutions.net/web/2009/07/16/oracle-introduces-patch-set-updates-psu-for-10204-database/ It's been on one of our test environments for a day now with no incident, though I see there's bug reported with it already. cheers- Jeff
