Hello Demantra Customers! Do you know what Edition Based Redefinition (EBR) is or how it impacts Demantra? EBS uses EBR for online patching.
There is a new update to the referenced MOS note below. Demantra DOES NOT support Edition Based Redefinition.
Edition-Based Redefinition enables you to upgrade an application's database objects while the application is in use, thus minimizing or eliminating down time. This is accomplished by changing (redefining) database objects in a private environment known as an edition. Only when all changes have been made and tested do you make the new version of the application available to users.
Edition-based redefinition allows multiple versions of PL/SQL objects, views and synonyms in a single schema, which makes it possible to perform upgrades of database applications with zero down time.
Large, mission critical applications built on Oracle Database 11g Release 1 and earlier versions are often unavailable for tens of hours while the application’s database objects are patched or upgraded. Oracle Database 11g Release 2 introduces edition-based redefinition, a revolutionary new capability that allows online application upgrades with uninterrupted availability of the application. When the installation of the upgrade is complete, the pre-upgrade application and the post-upgrade application can be used at the same time.
EBS supports EBR from the 12.2 release onwards in the online patching feature.
