This paper describes Edition-Based Redefinition (EBR) in the Oracle database --- a novel technology and methodology to build database application patches so that installation of these patches does not require application downtime. It discusses the challenge of zero-downtime application patch installation and shows how EBR can meet the challenge. Customer experience shows that EBR provides online application upgrade in several industries.
