Using Oracle Net Configuration Assistant

Run Oracle Net Configuration Assistant in standalone mode after the Oracle Database Client installation is complete to configure the listener, naming methods, net service names, and directory server usage.

Oracle recommends that you have information ready about the host name of the computer where the Oracle database is installed.
To start Oracle Net Configuration Assistant in standalone mode:
  1. Run netca from the $ORACLE_HOME/bin directory.
  2. Respond to the configuration prompts and screens as needed. The screens vary depending on the options you select. At any time during the configuration, if you have a question about what you are being asked to do, click Help.
