There are five phases or life cycles of ADOP which are:

a) PREPARE

b) APPLY

c) FINALIZE

d) CUTOVER

e) CLEANUP

Download the patch and unzip on $PATCH_TOP.

Prepare the system for patching.

$ adop phase=prepare

Apply the patch on system

adop phase=apply patches=21068635

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

adop phase=finalize

Cutover phase - Used to perform the transition to the patched environment

adop phase=cutover

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

$ . /EBSapps.env run

adop phase=cleanup

Now synchronise the technology level between patch and run fc_clone.

adop phase=fs_clone
