SEVERE:

Database connection through listener failed. Fix the error and run EM Configuration Assistant again.

Some of the possible reasons may be:

1) Listener port 1521 provided is incorrect. Provide the correct port.
2) Listener is not up. Start the Listener.
3) Database service SID is not registered with listener. Register the database service.
4) Listener is up on physical host and ORACLE_HOSTNAME environment variable is set to virtual host. Unset ORACLE_HOSTNAME environment variable.
5) Listener is up on virtual host. Set environment variable ORACLE_HOSTNAME=<virtual host>.
6) /etc/hosts does not have correct entry for hostname.
