Any thoughts wou be appreciated.

There is no way you can float this. You mean to glue the tongue and groove together like a nomal floating floor?...The solid oak - especially 2 1/4"- has too much movement. ..for starters you will have bowed boards and will be unable to tighten them, even with clamps the glue in the joints will give under pressure and the gaps will open back up. There are certain solid hardwoods that are made to float like "junckers" and there are ways to nail your oak to a floating subfloor of crossed layers of plywood but to try and glue the strips tongue and groove and float it just wont work.

You'll see few people giving a thumbs up to glueing solid wood down to concrete. You're asking for trouble and there almost a 100% chance that you'll have problems with your floor cupping down the road

You need to use a muti-ply engineered floor for glue down. Solid wood is meant to be nailed on a wood sub floor.

Floating subfloor, to nail into.
