Hi,
I have just upgraded my database from 12c to 19c using expdp/impdp. Since upgrade I have tried to match all parameters from 12c.

We are facing excessive logging in the new 19c DB. Earlier it was about 6GB per day compared to almost 70GB now. We are not using any materialized views.
Please can you guide if there are any new parameters or features that I need to change/tweak in 19c? The application connecting to the DB is exactly the same with no code changes.

I have already set db_lost_write_protect to none and temp_undo_enabled to true.

Thanks in advance,
Regards,
RD.

where  display_name like 'redo size';
