Answer 1

Try any of the following solutions

1. If the network port is not open, or it is blocked by a firewall, you can try TELNET.
2. If DB listener is not running or is binding to a different network interface, you can try either TELNET or else use Oracle client tools to connect.
3. If again the problem persists, you may please start the listener through command prompt (lsnrctl start)
