How to Synchronize FND_NODES, ADOP_VALID_NODES, and FND_OAM_CONTEXT_FILES in 12.2 When ADOP Phase=Prepare Fails with Error

How to Synchronize FND_NODES, ADOP_VALID_NODES, and FND_OAM_CONTEXT_FILES in 12.2 When ADOP Phase=Prepare Fails with Error

After a recent change or addition to the 12.2 E-Business Suite application tiers, adop phase=prepare fails with the following error:

Error

Cause
There is a synchronization error between fnd_nodes, adop_valid_nodes, and fnd_oam_context_files.

Solution
Due to the method required for "cleaning out" / "re-synchronizing" the following tables, it is EXPECTED / REQUIRED that the Applications have been shutdown.
The only thing running should be the Database Tier.
Note: A full backup should also be taken before any testing begins.

Test the following steps in a development instance, and then migrate accordingly once the desired result is confirmed:

1. Backup the fnd_oam_context_files, fnd_nodes, and adop_valid_nodes tables in the EBS env:

 sqlplus applsys/pwd

 create table fnd_oam_context_files_bkp as select * from fnd_oam_context_files;
create table fnd_nodes_bk as select * from fnd_nodes;
create table adop_valid_nodes_bk as select * from adop_valid_nodes;

2. Truncate the following tables:

truncate table fnd_oam_context_files;
truncate table fnd_nodes;
truncate table adop_valid_nodes;

3. Run AutoConfig on the DB tier
Confirm Autoconfig completes successfully

4. Run Autoconfig on the run file system.
    Source the Environment File to switch to run file system
    . /u01/app/EBSapps.env RUN

Confirm Autoconfig completes successfully

5. Run Autoconfig on the patch file system
   Source the Environment File to switch to patch file system
   . /u01/app/EBSapps.env patch

 Due to the method required for "cleaning out" / "re-synchronizing" the following tables, it is           EXPECTED / REQUIRED that the Applications have been shutdown.
 The only thing running should be the Database Tier.
 Before running Autoconfig on the patch file system the ebs_login trigger MUST be disabled
 After the successful completion of Autoconfig the ebs_login trigger MUST be re-enabled.
 This needs to be done as the SYSTEM schema user.
   a. Disable the ebs_login trigger using the following SQL.
     SQL> alter trigger ebs_logon disable;
  At this time Run autoconfig with the patch env sourced.
  Make sure Autoconfig completes ok
   b. Enable the ebs_login trigger using the following SQL.
  SQL> alter trigger ebs_logon enable;

6. After Autoconfig has been run successfully on all nodes, run the following two (2) queries in order to verify the tables have been correctly populated:
SQL> select node_id, platform_code, support_db D, support_cp C, support_admin A,
support_forms F, support_web W, node_name, server_id, server_address, domain, webhost, virtual_ip, status from fnd_nodes order by node_id;

SQL> select NAME,VERSION,PATH, STATUS from FND_OAM_CONTEXT_FILES;

Check adop with prepare phase. This time it should complete successfully.
$ adop phase=prepare

The prepare phase completed successfully.
adop exiting with status = 0 (Success)
