Which listener.ora to use when using EBS CDB/PDB
After upgrading my 11.2.0.4 EBS database to 19c CDB/PDB architecture, my configuration contains 2 listeners.ora files.
When I source my cdb environment, TNS_ADMIN points to: $ORACLE_HOME/network/admin
When I use my pdb environment, TNS_ADMIN points to: $ORACLE_HOME/network/admin/$CONTEXT_NAME
The environments works fine when using one of these listeners.
My question is which one to use?
Thanks.
