Issue:
During adop phase I faced the below error.
The table FND_INSTALL_PROCESSES created by AD Administration already exists.
Cause:
adadmin session was open to compile apps schema objects but it was stuck.
Solution:
1. Now take the backup of the FND_INSTALL_PROCESSES table
Connect as applsys because FND_INSTALL_PROCESS is owned by applsys schema.
Sqlplus applsys/<password>
create table fnd_Install_processes_23Feb22 as select * from fnd_Install_processes;
2. Check the both tables should have the same number of rows
SQL> select count(*) from fnd_Install_processes_23Feb22;
SQL> select count(*) from fnd_Install_processes;
3.. In same way take the backup of the AD_DEFERRED_JOBS table from applsys schema
sqlplus applsys/<password>
SQL>create table AD_DEFERRED_JOBS_23Feb22 as select * from AD_DEFERRED_JOBS;
4. Now backup the .rf9 files located at below path directory
$APPL_TOP/admin/$TWO_TASK/restart directory
Here adpatch session must be ended and the cursor should be back at the UNIX prompt.
$echo $ORACLE_SID or $TWO_TASK
cd $APPL_TOP/admin/$TWO_TASK
cp restart restart_23FEB
