Protocol Addresses

A network object is identified by a protocol address. When a connection is made, the client and the receiver of the request (listener, Oracle Names server, or Oracle Connection Manager) are configured with identical protocol addresses.

The client uses this address to send the connection request to a particular network object location, and the recipient "listens" for requests on this address, and grants a connection based on its address information matching the client information.

This appendix includes the following sections:

ADDRESSes and ADDRESS_LISTs

Protocol address are comprised of ADDRESS and ADDRESS_LIST elements:

ADDRESS

Purpose:

Defines a protocol address. This parameter may be embedded under ADDRESS_LIST or DESCRIPTION. A DESCRIPTION is typically only used in a tnsnames.ora or listener.ora file.
See Also: Each protocol has its own required parameters needed in the address, as explained in "Protocol Parameters".

Example:

(address= (protocol=tcp) (host=sales-pc) (port=1521))

ADDRESS
Purpose:	Defines a protocol address. This parameter may be embedded under ADDRESS_LIST or DESCRIPTION. A DESCRIPTION is typically only used in a `tnsnames.ora` or `listener.ora` file. See Also: Each protocol has its own required parameters needed in the address, as explained in "Protocol Parameters".
Example:	(address= (protocol=tcp) (host=sales-pc) (port=1521))

ADDRESS_LIST

Purpose:

Defines a list of addresses that share common characteristics.

Example:

(address_list= (load_balance=on) (address= (protocol=tcp) (host=sales-pc) (port=1521)) (address= (protocol=tcp) (host=hr-pc) (port=1521))) (address_list= (address= (protocol=tcp) (host=finance-pc) (port=1521)))

ADDRESS_LIST
Purpose:	Defines a list of addresses that share common characteristics.
Example:	(address_list= (load_balance=on) (address= (protocol=tcp) (host=sales-pc) (port=1521)) (address= (protocol=tcp) (host=hr-pc) (port=1521))) (address_list= (address= (protocol=tcp) (host=finance-pc) (port=1521)))

Recommended Port Numbers

Oracle Corporations recommends the following port numbers:

Port Description

1521

Default listening port for client connections to the listener. In future releases, this port number may change to the officially registered port number of 2483 for TCP/IP and 2484 for TCP/IP with SSL.

2481

Recommended and officially registered listening port for client connections to the Oracle8i JServer option using TCP/IP

2482

Recommended and officially registered listening port for client connections to the Oracle8i JServer using TCP/IP with SSL

2484

Recommended and officially registered listening port for client connections to the listener using TCP/IP with SSL

1575

Default and officially registered listening port for client connections to an Oracle Names server using TCP/IP or TCP/IP with SSL

1630

Default and officially registered listening port for client connections to Oracle Connection Manager

1830

Default and officially registered listening port for administrative commands to Oracle Connection Manager

Port	Description
1521	Default listening port for client connections to the listener. In future releases, this port number may change to the officially registered port number of 2483 for TCP/IP and 2484 for TCP/IP with SSL.
2481	Recommended and officially registered listening port for client connections to the Oracle8i JServer option using TCP/IP
2482	Recommended and officially registered listening port for client connections to the Oracle8i JServer using TCP/IP with SSL
2484	Recommended and officially registered listening port for client connections to the listener using TCP/IP with SSL
1575	Default and officially registered listening port for client connections to an Oracle Names server using TCP/IP or TCP/IP with SSL
1630	Default and officially registered listening port for client connections to Oracle Connection Manager
1830	Default and officially registered listening port for administrative commands to Oracle Connection Manager

Port Number Limitations

Oracle Corporation allows port numbers from 1 to 65535. Port numbers below 1024 are reserved for use by privileged processes on many operating systems.

If your listener is configured to use a port number below 1024, you will not be able to start it using LSNRCTL utility. LSNRCTL, even if itself running as root, cannot start the listener as root (on UNIX systems), however, you can always run listener executable (tnslsnr) as a root. This can be done by entering the command tnslsnr listener_name at the operating system prompt. Note that after the listener has been started it can be further administered (including stopping it) by LSNRCTL utility.
