AC-50480" Error Generating the "listener.ora" File

AutoConfig fails with the following error while generating the "listener.ora":

AC-50480: Internal error occurred: java.lang.Exception: Error while generating listener.ora.
Error generating tnsnames.ora from the database, temporary tnsnames.ora will be generated using templates

Cause:
The Network Topology tables had not been populated with the database information, either during the clone or during AutoConfig. Much of the Network Topology data seeding is done during AutoConfig on the dbTier.

Solution:
Rerun AutoConfig on all nodes, starting with the database node(s), as per standard procedures.
