<p>The <strong>eimChangeRegistryAlias()</strong> function allows you to add or
remove a registry alias for the defined registry.</p>
<p>One way to decouple names used by developers and names chosen by
administrators is by using registry aliases. When designing applications,
developers know the registry type their application uses and choose the
registry alias their program will use. Developers communicate to the
administrator which registry types their applications depend on along with the
EIM registry aliases that must be associated with that registry type. The
administrator adds the registry alias to the EIM registry of the appropriate
type. The application can use eimGetRegistryNameFromAlias() API which, given a
registry alias, returns the registry name for the entry(ies) with that registry
alias.</p>

<h3>Authorities and Locks</h3>
<dl>
<dt><em>EIM Data</em></dt>
<dd>Access to EIM data is controlled by EIM access groups. LDAP administrators
also have access to EIM data. The access groups whose members have authority to
the EIM data for this API follow:
<ul>
<li>EIM Administrator</li>
<li>EIM Registries Administrator</li>
<li>EIM authority to this individual registry</li>
</ul>
