Using Oracle Net Configuration Assistant to Configure Network Components

Oracle Net Configuration Assistant configures basic network components during installation, including:

• Listener names and protocol addresses

• Naming methods the client uses to resolve connect identifiers to connect descriptors

• Net service names in a tnsnames.ora file

• Directory server usage

Oracle Net Configuration Assistant runs automatically during software installation, as described in the Oracle Database installation guide. It can also be run after installation in standalone mode to configure naming methods, the listener, network service names in the tnsnames.ora file, and directory server usage.

To start Oracle Net Configuration Assistant do the following:

• On Linux and UNIX, run netca from the ORACLE_HOME/bin directory.

• On Microsoft Windows, select Programs from the Start menu, and then select Oracle - HOME_NAME. Next, select Configuration and Migration Tools, and then Oracle Net Configuration Assistant.
