"adop phase=finalize" Fails As ADOP Cannot Detect Any Application Tier Nodes In FND_NODES table. Ensure ICM is running and run autoconfig on all nodes

When attempting to perform "adop phase=finalize" the following error occurs.

ERROR
[UNEXPECTED]adop cannot detect any application tier nodes in FND_NODES table. Ensure ICM is running and run autoconfig on all nodes
[UNEXPECTED]Error while checking if this is a multi node instance

The issue occurs due to a null value for the concurrent/admin node status column in table FND_NODES.

More details are available via the following unpublished defect:
Bug 18533116 - AD:ADOP IN HOTPATCH FAILED FOR R12.TXK.C.DELTA.5

"In AD.Delta.4+one off patches we have a dependency on FND_NOTES.STATUS column

The column will be automatically set to 'Y' when ICM is up.

When the ICM is down the query will not detect any nodes with status 'Y',  and adop proceeds with only the current/admin node (inserts rows into AD_ADOP_SESSIONS for current/admin node only."

Fix:

To resolve the issue, test the following steps in a development instance and migrate accordingly:
Test the following steps:

    A. Set the "run" Application Tier environment
    B. Start ICM
    C. Run "adop phase=finalize" again.
