- Online Patching:
One of the key Feature of R12.2 is the switch to online patching. This helps to reduce significantly the downtime traditionally needed for patching and related maintenance activities
An edition is a private environment in which you can redefine database objects. With online patching, patches are applied to a separate edition while users are working with the original edition. Subsequently, the system is cut over to make the patch edition the new production edition. After the upgrade to Release 12.2, all future patches and maintenance packs will be applied online, requiring only a short cutover period to make the new functionality active.
2. Application Tier
A key change to the Oracle E-Business Suite technology stack is the adoption of the Oracle WebLogic Server component of Oracle Fusion Middleware, in association with the Oracle HTTP Server component. Corresponding changes have been made to the various application tier services.
Additionally, Oracle E-Business Suite Release 12.2 has a second file system for the application tier. The second file system facilitates the online patching functionality for Oracle E-Business Suite patches and follows the best practices recommendations of Oracle technologies for minimal patching disruption.
