How do I open a specific port on RHEL 6.4?

I’m setting up the remote connection to oracle database and it requires that the connection should be established through port 1521 by default. However, i’m getting the error repeatly: [Oracle JDBC Driver]Error establishing socket to host and port: :1521. Reason: Connection refused Checking deeper, I realize that the port 1521 cannot be connected on the local machine: telnet localhost 1521
