Oracle E-Business Suite Release 12.2 includes a new Online Patching feature that allows for Oracle E-Business Suite patches to be applied while users are still online and using the Oracle E-Business Suite functionality. The implementation of Oracle E-Business Suite Online Patching relies on the new Edition-based Redefinition (EBR) technology from the database and the new Online Patching infrastructure, including the new file system. For an introduction to Online Patching, see the Oracle E-Business Suite Concepts Guide.
