Define "excessive" and excessive relative to what.
A SQL statement generates the redo it needs to generate not more so can't be excessive.

>>Find Out Which SQL Statements
Seems Sessions Yes. Statements No.
Did you try Snapper?

Demo with excellent discussion. Got nothing more to say.

Change less data, generate less redo.
