Let’s start with the Rapid Install of R12.2. Part II

Part two will take you through the Installation of 12.2. One of the important things to keep in mind during the installation is after laying down the File System using the Rapid Install, do not change the password for any products. Doing so may result in the following error: 'ORA-01017: invalid username/password; logon denied, occurred while executing the SQL statement: CONNECT JTF/*****'

One of the important prerequisite is if you haven't applied R12.AD.C Patch 10117518 yet, apply it following the instructions in the Upgrade Guide and the Patch's readme. As per Readme file of Patch 10117518, it requires patch#16595190:R12.AD.C to be merged with it and apply in Entirety.

Maintenance mode should normally be enabled when patching the Oracle E-Business Suite and disabled when users are logged on to the system.  See the Oracle E-Business Suite Maintenance Utilities manual for more information about the maintenance mode.

The classic patching model is designed to minimize downtime by running as fast as possible, using whatever resources as needed. In contrast, the online patching model is designed to minimize downtime by allowing patching operations to be performed while users remain on the system.

In essence, online patching is performed as follows:
1. A copy is made of the running system.
2. Patches are applied to the copy while users continue to access the running system.
3. Transparently to users, the copy becomes the new running system.
4. What was the original running system (now obsolete) is deleted.
This introduces the concept of a patching cycle that consists of several phases, in contrast to the model used in the previous releases. These phases are prepare, apply, finalize, cutover, and clean-up.

Verifying completion of the programs is recommended. The upgrade process creates numerous concurrent program requests. Once you bring up the application tier, these programs run automatically to complete tasks such as data clean-up and upgrades to historical data, among others. Before you continue, be sure all the concurrent programs generated by the upgrade have run successfully.
