Explain why you need SET TRANSACTION READ ONLY again. What does that have to do with data changing? You have made YOUR transaction read only. That does not affect any other transaction anywhere on the planet.
I would suggest you examine Oracle's transaction model specifically as it relates to multiversion read consistency and system change numbers (SCN).
The only thing you have done is tie your own hands.
