<h1>Local Naming Overview</h1>
<p><a href="n8ahelplocal_naming00000153.htm">Local naming</a> is one of the primary <a href="n8ahelpnaming_method.htm">naming methods</a> used to resolve a simple name, a <a href="n8ahelpnet_service_name.htm">net service name</a>, to a <a href="n8ahelpconnect_descriptor.htm">connect descriptor</a> that the client uses to connect to a database or service. Local naming stores net service names and their connect descriptors in a local <a href="n8ahelptnsnamesora_file.htm">tnsnames.ora file</a>.</p>
<p>An end user enters a connect string that includes the net service name in the following format:</p>
<p><code dir="ltr">CONNECT</code> <span class="italic">username/password@net_service_name</span></p>
<p>In the following example sales is the net service name that is looked up in the tnsnames.ora file:</p>
<p><code dir="ltr">CONNECT scott/tiger@sales</code></p>
<p>The connect descriptor returned to the client includes the:</p>
<ul>
<li>
<p>Protocol address location of the listener</p>
</li>
<li>
<p><a href="n8ahelpservice_name.htm">Service name</a> of the database</p>
</li>
</ul>
<p>The client uses this information to connect to a listener. The listener, configured with the same address information, receives the request. If the listener is listening for requests to the same database service as specified in the client's connect descriptor, a connection is granted.</p>
