Configuring Your Client Network
Oracle Net Configuration Assistant is a tool that enables you to configure your network environment to enable Oracle clients to connect to an Oracle9i database. Oracle Net Configuration Assistant can be automatically started from Oracle Universal Installer through most installation types or manually started as a standalone tool.
Depending on the installation type selected, Oracle Net Configuration Assistant configures your network in one of the following ways:
■Automatically configures your network for standard database connection methods with minimal user input
■Creates a customized network by prompting for extensive input
Configuration consists of creating and modifying a series of network files located in the ORACLE_BASE\ORACLE_HOME\network\admin directory.
