The E-Business Suite R12.2.6 Technical Upgrade Class

TruTek R12.2 Upgrade Training

The R12 Upgrade class is 5 days long and starts with a Release 12.1.1 Vision Instance and upgrades that instance to Release 12.2.6. The database version used is 12.1.0.2. Basic concepts and downtime-reducing steps such as staging from the R12.2 DVDs are covered. The class size is usually limited to 4 to 6 students, and each student has a quad core 64 bit Linux server to perform the upgrade. Minimizing downtime is a common theme throughout the R12.2 Upgrade class. Downtime-reducing techniques include merging patches, how to use downtime mode to apply some patches, adjusting the number of workers, using fast IO, and the benefits of snapshots. Online patching is the major technical change in the R12.2 architecture; we will spend considerable time understanding how to apply online patches, the consequences of online patching on customizations, and how to find and fix online patching compatibility issues. Another technical architecture change is the use of the Weblogic server.  In case you are upgrading from 11.5.10.2, we will cover the pre-upgrade steps and 11i patches required for the upgrade. We will cover the additional steps required if you are upgrading from 11.5.10.2.


It is recommended that class attendees take the R12.2 Apps DBA class if they are not familiar with EBS upgrades and not experienced with the Oracle E-Business Suite
