Recently ? What do you speak about ?
"When any transaction is committed, database Commit Number is incremented and
its value is associated with this transaction".
Commit Number (CN) is *not* a System Change Number (SCN).
SCN was introduced with physical backup more than 10 years ago.
IIRC, the journal counter does exactly the same.
I have no idea what is "journal counter"
