Patch Application Life Cycle

One of my friend, Abhishek recently defined the Patch application life cycle for Fusion SOA Suite.

Steps

1.    Get patch from Oracle.
2.    Study Readme for applying patch.
3.    Try to apply Patch.
4.    Patch application fails.
5.    Confirm back to Oracle.
6.    a. Oracle provides an un-official Patch. Goto Step 8
                 OR
        b. Oracle Unable to provide a solution.
7.    Devise a workaround on your own to apply patch.
8.    Apply Patch successfully.
9.    Ask all the application teams to test their application.
10.  Patch does not solve the issue it was applied for.
11.  Rollback Patch.
12.  Ask all the application teams to test their application.
