This could compromise the access to Production data or cause unintentional performance issues.

Do not execute a Commit command for update / delete actions in Production before verifying the results (using before and after 'select' queries).

Do not use parallel hints in 'select' queries on Production database for the sake of report creation; if you must run such queries for reports – do it during off-peak hours, or on an auxiliary/ Business Continuance Volume (BCV) database.
