See Chapter 10, "Exporting Naming Data to a Directory Server," of the <em>Oracle10i Net Services Administrator's Guide</em> for further information.</li> </ul> <p>You can create net service aliases for directory naming objects-- <a href="n8ahelpnet_service_name.htm">net service names</a> or database services--in a directory server. A net service alias stores the name of the object it is referencing.</p> <p>When a client requests a directory lookup of a net service alias, the directory determines that the entry is a net service alias and completes the lookup as if it is the referenced entry. For example, a net service alias of <span class="Code">salesalias</span> can be created for a net service name of <span class="Code">sales</span>. When <span class="Code">salesalias</span> is used to connect to a database service, as in <span class="Code">CONNECT scott/tiger@salesalias</span>, it will actually resolve to and use the connect descriptor information for <span class="Code">sales</span>.</p> <p>There are two main uses for net service name aliases:</p> <ul> <li> <p>Use a net service name alias as a way for clients to refer to a database service or net service name by another name.</p> </li> <li> <p>Use a net service name alias in one <a href="n8ahelpOracle_Context.htm">Oracle Context</a> for a database service or net service name in a different Oracle Context. This enables that database service or net service name to be defined once in the directory server, but used out of other Oracle Contexts.</p> </li> </ul> <p>To create a net service name alias:</p> <ol> <li> <p>In the navigator pane, expand <span class="gui-object">Oracle Net Configuration > Directory > Service Naming > Aliases.</span></p> </li> <li> <p>Choose plus (+) from the toolbar, or choose <span class="gui-object">Edit > Create</span> from the menu bar. The <a href="nmhelp_create_net_service_alias.htm">Create Net Service Alias</a> dialog box appears.</p> </li> <li> <p>In the <span class="gui-object">Net Service Alias</span> field, enter a name for the net service alias.</p> </li> <li>In the Net Service or Database Service box, enter the following information about the net service name or database service: <ul> <li><span class="gui-object">Oracle Context:</span> Specify the Oracle Context of the database service or net service name by selecting one from the list or entering one in the field.</li> <li><span class="gui-object">Name:</span> Specify the <a href="n8ahelpDistinguished_Name_DN.htm">distinguished name (DN)</a> of the database service or net service name by selecting one from the list or entering one in the field.</li> </ul> </li> <li>Choose <span class="gui-object">Create.</span></li> </ol> <h2>Related Topics</h2> <p><a href="n8ahelpDatabase_Identification_by_Servi.htm">Database Identification by Service Name</a></p> <p><a href="n8ahelpnet8_overview.htm">Oracle Net Services Overview</a></p> <P CLASS="zz-legal-notice">Copyright © 1996, 2009, Oracle and/or its affiliates.
