This section describes the new networking features of Oracle Database 10g and provides pointers to additional information. New features information from previous releases is also retained to help those users migrating to the current release.
The following sections describe the new networking features:
The new features for Oracle Net Services in Oracle Database 10g include:
Naming Changes
Easy Connect Naming Method for TCP/IP Environments
For TCP/IP environments, you can simplify client configuration by using the easy connect naming method. The easy connect naming method simplifies network management by allowing clients to connect to Oracle Database database services without first configuring net service names. Instead, clients make connections with the host name and optional port and service name of the database.

"Using the Easy Connect Naming Method" for configuration detailsDe-support of Oracle Names
Oracle Names is no longer supported as a naming method in Oracle Database. You must migrate to directory naming for centralized storage of connect identifiers.
Simplified Directory Naming Configuration
Clients no longer require local directory usage configuration (ldap.ora
). If an Oracle Internet Directory Server is registered with the Domain Name System (DNS), clients can automatically locate a directory server, eliminating the need for local configuration.
Backing Up Directory Naming Entries to a Local Naming File
You can now export directory naming entries into a local tnsnames.ora
file. Clients can use the locally saved file when a directory server is unavailable or when clients have not been updated to use directory naming.

High-Speed Network Support
Oracle protocol support now includes support for the SDP protocol for Infiniband high-speed networks. The SDP protocol is a high-speed communication protocol that speeds up performance between the Oracle Application Server and the database. By using SDP, applications place most of the messaging burden upon the network interface card, freeing the CPU for other tasks.
NOTE:
The SDP protocol is only available on some platforms. Please refer to the operating system-specific documentation for more information.See Also:

To ensure the continuous flow of data and better utilization of network bandwidth, you can specify the I/O buffer space limit for send and receive operations of sessions.
See Also:
"Configuring I/O Buffer Space" for configuration detailsNetwork Outage Detection Parameters
You can limit the time permitted for send and receive operations, preventing the database server from being blocked by a network I/O request.

Oracle Enterprise Manager provides the following support in Oracle Database 10g:
Configuration and administration of listeners
Configuration of the local naming and directory naming methods
Configuration of network files across multiple file systems

"Oracle Enterprise Manager"Simplified Dispatcher Configuration
In 10g, the DISPATCHERS parameter does not have to be specifed in order to enable shared servers. If it is not and shared server is configured then a dispatcher listening on TCP/IP port 1521 is started automatically. Configuration of the DISPATCHERS
parameter is required for dispatchers that do not listen on the TCP/IP protocol or require other optional subparameters.
