Patching procedure in oracle apps R12.2

From R12.2 onwards oracle has introduced online patching functionality.

Phases of ADOP(online patching):

In R12.2.0 we have ADOP – AD Online Patching instead of adpatch. There are five phases or life cycles of ADOP which are:

1) PREPARE

2) APPLY

3) FINALIZE

4) CUTOVER

5) CLEANUP

1. Prepare phase - Used to start a new online patching cycle.

$ adop phase=prepare

2. Apply phase - Used to apply one or more patches to the patch edition of an Oracle E-Business Suite system:

$ adop phase=apply patches=637432,654376 workers=8

3. Finalize phase - Used to perform the final patching operations that can be executed while the application is still online:

$ adop phase=finalize

4. Cutover phase - Used to perform the transition to the patched environment:

$ adop phase=cutover

5. Cleanup phase - Used to remove old objects that are no longer needed:

$ adop phase=cleanup

Abort command:

If necessary, an online patching cycle can be terminated, with the actions taken being discarded.

The command to perform this operation is:

$ adop phase=abort

The Online Patching Cycle:

(Note: This abort command is only available up to (but not including) the cutover phase. After cutover, the system is running on the new edition, and abort is no longer possible for that patching cycle.)
