Oracle E-Business Suite Release 12.2: Online Patching FAQ (Doc ID 1583902.1)

To implement Online Patching Run reports/scripts mentioned in Using the Online Patching Readiness Report in Oracle E-Business Suite Release 12.2 [1531121.1]

• In Oracle EBS 12.2. It is the ability to patch a running system without having to take the system down.
• It will enable R12.2 PATCH Environment. Patches must be applied before enabling ADOP.
• All AD_ZD packages should be valid before enabling them.
• Once you enable ADOP i.e. Online Patching you cannot apply any patches through ADPATCH.
• If you still want to apply any patch via adpatch, source ENABLE_ADPATCH=yes. (if oracle recommends)
• All patches applied using adop utility will be applied to PATCH environment i.e. fs2.
• When you want to make the patches live you can execute adop using cutover phase. It will switch filesystems.
• To synchronize both filesystems i.e. fs1 and fs2 you can execute adop using fs_clone phase.

Phases:

1. adop phase=prepare ->; copies the application code
2. adop phase=apply ->; apply patches to PATCH Environment
3. adop phase=finalize ->; makes ready the system for cutover
4. adop phase=cutover ->; bounce the system and does filesystem switchover. fs2 becomes RUN environment. 
5. adop phase=cleanup -> remove obsolete objects.
6. adop phase=fs_clone ->; synchronize filesystems.

Example How apply patches using adop.

1. adop phase=fsclone

    it will synchronize run file system to patch file system for custom_top

2. adop phase= prepare

     synchronize fs1 to fs2

3. adop phase=apply patche=patch_number

    Patch will start if the patch fail you can find out what worker file using adctl then you can restart the patch again

4. adop phase=apply patches=patch_number restart=yes

     once patch completed.

5 adop phase=cutover

     Mid Tier bounce where the run and patch system will swapped and new run file system is prepared form the existing patch file system

 6 . adop phase= cleanup

The full patch cycle been complete.
