for this topic supports the latest PTF levels for HTTP Server for i5/OS .
|

It is recommended that you install the latest PTFs to upgrade to the latest
|
||
|
|
level of the HTTP Server for i5/OS. Some of the topics documented here are
|
||
|
|
not available prior to this update. See <a href="http://www-03.ibm.com/servers/eserver/iseries/software/http/services/service.html" target="_blank">http://www.ibm.com/servers/eserver/iseries/software/http/services/service.htm</a> <img src="www.gif" alt="Link outside Information Center" /> for more information. </div>
|

|
<p>Set up your highly available HTTP Server instance using the clustering
|
||
|
|
CL commands. Before using the following commands, see <a href="../rzaig/rzaigicclust.htm">Clusters</a> for
|
||
|
|
more information. </p>
|
||
|
|
<p>The following is a subset of the Clustering CL commands that can be used
|
||
|
|
to perform clustering operations. See <a href="rzaieclcommands.htm">CL commands for HTTP Server</a> for
|
||
|
|
more information. </p>
|
||
|
|
<p>To create a cluster, use the following CL command: </p>
|
||
|
|
<dl class="block"><dt class="dlterm"><a href="../cl/crtclu.htm">CRTCLU</a></dt>
|
||
|
|
<dd><strong>Create Cluster</strong> creates a new cluster for one or more nodes. </dd>
|
||
|
|
</dl>
|
||
|
|
<p>To add nodes to an existing cluster, use the following CL command:</p>
|
||
|
|
<dl class="block"><dt class="dlterm"><a href="../cl/addclunode.htm">ADDCLUNODE</a> </dt>
|
||
|
|
<dd><strong>Add Cluster Node Entry</strong> adds a node to the membership list of an
|
||
|
|
existing cluster. </dd>
|
||
|
|
</dl>
|
||
|
|
<p>To start a node in the cluster, use the following CL command: </p>
|
||
|
|
<dl class="block"><dt class="dlterm"><a href="../cl/strclunod.htm">STRCLUNOD </a></dt>
|

in the cluster.<div class="note"><span class="notetitle">Note:</span> It is suggested that you start a new cluster node from
|

|
|
a node that is already active. </div>
|

</dd>
|

|
|
</dl>
|

<p>To determine the status of a node in a the cluster, use the following CL

command: </p>
|

<dl class="block"><dt class="dlterm"><a href="../cl/dspcluinf.htm">DSPCLUINF </a></dt>

<dd><strong>Display Cluster</strong> Information displays the status of a node in a
|
||
|
|
cluster. All nodes should be in the <em>Active</em> state.</dd>
|
||
|
|
</dl>
|
||
|
|
<p>To perform a swtichover in the case of a Primary/Backup configuration,
|
||
|
|
use the following CL command: </p>

switchover of the cluster resource group by changing the current roles of
|
||
|
|
nodes in the recovery domain. </dd>

||
|
|
</dl>
|
||
|
|
<p>To remove a node from a cluster, use the following CL command: </p>

<dl class="block"><dt class="dlterm"><a href="../cl/rmvclunode.htm">RMVCLUNODE</a> </dt>
