There is no information in the table FND_NODES for the database node.
This means that autoconfig has not been executed in the database tier or there was a problem
when it was executed in the database tier.
So you need to run autoconfig on the database tier to gather the information.
There is no database node declared in the FND_NODES table
To implement the solution, please execute the following steps:
1. Ensure that you have taken a backup of your system before applying the recommended solution.
2. Clean the Data Topology Model
SQL> EXEC FND_CONC_CLONE.SETUP_CLEAN;
3. Run AutoConfig on all tiers, firstly on the DB tier and then the APPS tiers, to repopulate the required system tables
