ADOP utility in R12.2.10

 Overview of ADOP in Oracle EBS R12.2

ADOP – stands for Application DBA Online Patching which is introduced in Oracle EBS R12.2 

version to patch oracle applications while a system is available for users during Patching.

NOTE: The adop utility always runs from the run edition file system. 

Full application functionality is retained as patch execution proceeds, 

until the cutover phase is reached.

The online patching cycle consists of five of high level phases:

prepare: Prepares the environment for patching.

apply: Applies the specified patches to the environment.

finalize: Performs any final steps required to make the system ready for cutover.

cutover: Shuts down application tier services, makes the patch edition the new run edition, 

and then restarts application tier services. This is the only phase the involves a brief downtime.

cleanup: Removes obsolete code and data from old editions.
