<p>Database Upgrade Assistant enables you to upgrade an existing database to Oracle9<em>i</em> when you have completed an Oracle9<em>i</em> installation. You must complete a number of steps prior to upgrading with Database Upgrade Assistant. These include performing a full backup of your current production database, and reviewing required planning and backup preparations prior to beginning an upgrade.

Oracle Enterprise Manager Configuration Assistant

<p>Oracle Enterprise Manager Configuration Assistant configures the Oracle Management Server on a local system. It can create, upgrade or delete a repository, and edit existing configurations. A repository is a set of database tables that must be located in any Oracle database accessible to the Oracle Management Server. The Oracle Management Server uses a repository to store all system data, application data, and information on the state of managed nodes distributed throughout the environment.

<strong>Client Installation

</font>
</dt>
<p>For Oracle9<em>i</em> Administrator and Runtime Client installations, the local or directory naming method is selected based on whatever you choose to use a directory service. For Oracle9<em>i</em> Custom Client installation, Oracle Net Configuration Assistant prompts you to:
</p>
<p>Complete directory usage configuration if you have a directory server. Select a naming method to use for accessing the database.
</p>
<ul>
<li type="disc">
<p>Local naming specifies a net service name to resolve network addresses. This name is configured and stored in configuration files on each client.

</p>
</li>
</ul>
<p>Depending on the naming method you select, you are prompted to provide additional information.
</p>
<p>Oracle Net Configuration Assistant then creates your Oracle Net client environment by configuring the following files:
</p>
<ul>
<li type="disc">
<p><code>sqlnet.ora:</code> configures the naming methods a client uses to resolve a name to a connect descriptor. The Assistant configures the client&#039;s domain as the default domain. This domain is automatically appended to any unqualified net service name given in the connect string. 
</p>
</li>
</ul>
<ul>
<li type="disc">
<p><code>tnsnames.ora: </code>configures a net service name if using local naming.

Oracle Workflow Configuration Assistant
</font>
</h3>
<p>The Oracle Workflow Configuration Assistant automatically creates an Oracle Workflow database account to which the Oracle Workflow database objects are installed. Oracle Workflow is only installed automatically if you install it at the same time as you create your database. If you run the Oracle Universal Installer to install Oracle Workflow on an existing database, then the Oracle Universal Installer only copies the Oracle Workflow files to your file system; it does not automatically run those files to perform the installation. You must manually run an installation&#047;upgrade script to complete the installation. This precaution helps ensure that any previous installation of Oracle Workflow in an existing database is upgraded correctly.
