<h1 class="topictitle1">Configure your server to use SNTP as the time maintenance application</h1>
|
|
<div><p>View this topic to learn how to use the Simple Network Time Protocol
|
|
(SNTP) application for time maintenance.</p>
|
|
<p>If you do not have a time maintenance application of your own or you want
|
|
to take advantage of the IBM-supplied time maintenance application, you can
|
|
use SNTP.</p>
|
|
<p>For more information about the various ways you can configure SNTP, see
|
|
the following topics:</p>
|
|
<dl><dt class="dlterm">SNTP client</dt>
|
|
<dd>Specifies how to configure SNTP as a client. When SNTP is configured as
|
|
a client, the iSeries™ server
|
|
retrieves a time value from an external time source. You can specify from
|
|
which source to retrieve the time value. This external time value is compared
|
|
to the iSeries system
|
|
time. If the iSeries time
|
|
value does not match the external time source, a time adjustment begins. The iSeries system
|
|
time is adjusted until the desired time value is reached.</dd>
|
|
<dt class="dlterm">SNTP server</dt>
|
|
<dd>Specifies how to configure SNTP as a server. When SNTP is configured as
|
|
a server, the iSeries server
|
|
sends its system time to the clients connected to it. If a client's time values
|
|
do not match the iSeries SNTP server time, a time adjustment
|
|
begins. The client's system time is adjusted until the desired time value
|
|
is reached.</dd>
|
|
<dt class="dlterm">Scenario: Synchronize clocks with iSeries server (SNTP as a client and
|
|
server)</dt>
|
|
<dd>Specifies how to configure SNTP to function as a client and as a server.
|
|
In this situation, the system specified as the SNTP client server retrieves
|
|
the time from an external time source and uses that to maintain its local
|
|
system time. The local system time is then also provided to other systems
|
|
connected to it. The local system's time value is compared to each client's
|
|
system time. If any of the system's time values differ from the local system
|
|
time on the server specified as the SNTP server, a time adjustment begins.</dd>
