Martin has busied himself to combine the recommended patch sets for OBIEE 11g into one single useful KM note.
(This one contains the recommendations for 220.127.116.11 as well as those for 18.104.22.168)
So if you are looking for update/patch information for your OBIEE installation - this is most likely a useful stop.
And as patching is an ongoing process you may want to bookmark this KM doc, as I am sure Martin will keep this current as new patches come out.
Oh - and if you are looking for upgrade information from 22.214.171.124 to 126.96.36.199, KM Doc ID 1434253.1 might just be the thing you are looking for.
