The second note mentions about the steps for registering the custom applications. Which is done already.
When we go through the first note, It tells us to apply the custom code in the form of manual patches, which is nothing but executing a code inside a shell script.
But we wanted to run adop phase=apply passing a custom driver. Let us know how this can be achieved
If you are talking about synchronizing custom tops between fs1 and fs2 refer to
Section 1.5.4 in
Developing and Deploying Customizations in Oracle E-Business Suite Release 12.2 (Doc ID 1577661.1)
If you are talking about developing custom patch you can refer the same document above.
The requirement is to deploy a custom code in a similar manner how we apply the
adop phase=apply patches=xxxxxxxxxx
Meaning, a custom code has to be developed in the form of a u driver, so that the adop can pick up the same while apply phase
