<h1 class="topictitle1">Central server</h1>
<div><p>Provides services such as license management and other client management
functions.</p>
<p>The central server provides the following services for clients:</p>
<ul><li>License management <p>The initial request from either Data Transfer or
PC5250 reserves a license for that iSeries™ Access for Windows<sup>®</sup> user.
The server remains active until the release delay timeout expires. The license
will be held until it is released or the server job is ended. To see which
licenses are reserved, use iSeries Navigator to view the iSeries system's properties.</p>
</li>
<li>Retrieve conversion map <p id="rzaiimst21__SPTIDX185"><a name="rzaiimst21__SPTIDX185"><!-- --></a>The central server retrieves
conversion maps for clients who need them. These conversion maps are usually
used for ASCII to EBCDIC conversions and for EBCDIC to ASCII conversions.
Coded character set identifiers (CCSID) must be supplied. The client can request
a map by giving the correct source CCSID, the target CCSID, and a table of
code points to be converted. <span id="rzaiimst21__SPTIDX186"><a name="rzaiimst21__SPTIDX186"><!-- --></a>The server then returns the
correct mapping for the client to use.</span></p>
</li>
</ul>
<p>The programs listed in the following table are included with this server.</p>
