A set of rules that defines how data is transported across networks. Oracle support with Oracle Net Manager include:
IPC
The Interprocess communication (IPC) protocol is used for client applications that are on the same computer as the listener. IPC can provide a faster local connection than TCP/IP.
Named Pipes
Named Pipes is used on PCs that are not using TCP/IP. Named Pipes is available only on Windows NT.
TCP/IP
The Transmission Control Protocol/Internet Protocol (TCP/IP) is the de facto standard Ethernet protocol used for client/database server conversation over a network. TCP/IP enables an Oracle application on a client to communicate with remote Oracle databases through TCP/IP (if the Oracle database is running on a host system that supports network communication using TCP/IP).
TCP/IP is the standard networking protocol. It is used overwhelmingly by both UNIX and PC based networks. It is also the protocol with which Internet connections are made.
TCP/IP with SSL
The TCP/IP with Secure Sockets Layer (SSL) protocol enables an Oracle application on a client to communicate with remote Oracle databases through TCP/IP and SSL (if the Oracle database is running on a host system that supports network communication using TCP/IP and SSL). TCP/IP with SSL is only for use with the SSL authentication method.
Note: Your operating system may support additional protocols.

An address that identifies the network address of a network object.
When a connection is made, the client and the receiver of the request, such as the 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. It is important to install the same protocols for the client and the connection recipient, as well as to configure the same addresses.
Protocol address are comprised of ADDRESS and ADDRESS_LIST elements.

Type of network object information stored in an Oracle Names server. Oracle Names servers support the following record types:
- A.SMD: Network addresses, including database service addresses and net service names
- CNAME.SMD: Aliases for any network object
- DL.RDBMS.OMD: Global database links
- DLCR.RDBMS.OMD: Link qualifiers
- NS.SMD: Oracle Names servers' addresses
- V1ADD.NPO.OMD: SQL*Net Version 1 connect string

The listener , Oracle Names server, and Oracle Connection Manager are identified by a protocol address. Clients that want to use these services must also be configured with the same address. The following table describes the parameters used by the supported Oracle protocols:
|
Protocol |
Parameter |
Description |
| IPC | PROTOCOL |
Specify ipc as the value. |
|
|
KEY | Specify unique name for the service. Oracle Corporation recommends using the service name or the Oracle System Identifier (SID) of the service. |
| Named Pipes | PROTOCOL |
Specify nmp as the value. |
| SERVER | Specify the name of the Oracle server computer. | |
| PIPE | Specify the pipe name to connect to the database server. This name can be any arbitrary name. | |
| TCP/IP and TCP/IP with SSL | PROTOCOL | Specify tcp as the value for TCP/IP, or specify tcps as the value for TCP/IP with SSL. |
| HOST | Specify the host name or IP address of the computer. | |
| PORT | Specify the listening port number. |

The local, most granular level entry name. It has no other qualifying entry names that would serve to address the entry uniquely. In the example, cn=sales,dc=us,dc=example,dc=com,cn=sales is the RDN.

A set of rules that determine what can be stored in a directory server. Oracle has its own schema that is applied to many types of Oracle entries, including Oracle Net entries. The Oracle schema for Oracle Net entries includes the attributes the entries may contain.

A process that acts a connection point from the listener to the database server. A service handler can be a shared server dispatcher or dedicated server or a Database Resident Connection Pooling broker. During a connection, a connect descriptor is passed to the listener. It is the job of the listener job to determine what kind of service handler will best service client requests.

A buffer that Oracle Net uses to place data before transmitting across the network. Oracle Net sends the data in the buffer either when requested or when it is full. When large amounts of data are being retrieved and when packet size is consistently the same, it may speed retrieval to adjust the default SDU size.
