<p>Oracle protocol support is a component of Oracle Net. It includes the following:
</p>
<ul>
<li type="disc">
<p> IPC protocol support
</p>

<ul>

</ul>
<ul>
<li type="disc">
<p> TCP&#047;IP with SSL protocol support
</p>
</li>
</ul>
<p>The IPC, TCP&#047;IP, and TCP&#047;IP with SSL protocol supports each have an address specification that is used in Oracle Net Services configuration files and in the DISPATCHER initialization parameter in the <code>init</code><em><code>sid</code></em><code>.ora</code> file. The following sections describe the address specifications for each of the protocol supports.

TCP&#047;IP Protocol Support

<p>TCP&#047;IP is the standard communication protocol used for client&#047;server communication over a network.

<p>Oracle Corporation recommends that you reserve a port for the listener in the <code>&#047;etc&#047;services</code> file of each Oracle Net Services node on the network. The default port is 1521. The entry lists the listener name and the port number, for example:
</p>
<pre><em><code>oraclelistener</code></em>    1521&#047;tcp

</pre>
<p>In this example <em><code>oraclelistener</code></em> is the name of the listener, as defined in the <code>listener.ora</code> file. Reserve more than one port if you intend to start more than one listener.
</p>
<p>If you use intend to use SSL, you should define a port for TCP&#047;IP with SSL in the <code>&#047;etc&#047;services</code> file. Oracle Corporation recommends a value of 2484. For example:
</p>
<pre><em>oraclelistenerssl</em>     2484&#047;tcps

</pre>
<p>In this example <em><code>oraclelistenerssl</code></em> is the name of the listener, as defined in the <code>listener.ora</code> file. Reserve more than one port if you intend to start more than one listener.
