<h2>Cluster Resource Services Characteristics</h2>
|
||
|
|
|
||
|
|
<p>A set of APIs is provided to enable a developer to produce cluster
|
||
|
|
management facilities and to integrate the facilities with other system
|
||
|
|
management capabilities. The APIs provide access to the i5/OS<SUP>(R)</SUP> Cluster Resource
|
||
|
|
Services functions and are described in the sections that follow the
|
||
|
|
introduction.</p>
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
<p>CL commands for clustering are available in the operating system, should you
|
||
|
|
like to experiment with clustering before using the Cluster APIs.</p>
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
<p>The Cluster Resource Services components are:</p>
|
||
|
|
|
||
|
|
<ol type="1">
|
||
|
|
<li>Cluster Control (CCTL)
|
||
|
|
|
||
|
|
<p>CCTL provides configuration, activation, and management functions for the
|
||
|
|
cluster and nodes in the cluster through a set of APIs. These APIs are
|
||
|
|
described in <a href="clust2a4TOC.htm">Cluster Control APIs</a>.</p>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>Cluster Resource Group Manager (CRGM)
|
||
|
|
|
||
|
|
<p>CRGM provides object management functions for the cluster resource group
|
||
|
|
(*CRG) object through a set of APIs. These APIs are described in <a href=
|
||
|
|
"clust3a1TOC.htm">Cluster Resource Group APIs</a>.</p>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>Cluster Resource Group Exit Program
|
||
|
|
|
||
|
|
<p>This user provided program is specified on the definition of a cluster
|
||
|
|
resource group. The program is responsible for handling all of the action codes
|
||
|
|
that are passed to it by the Cluster Resource Group Manager. The action codes
|
||
|
|
are described in the APIs that result in a call to the exit program. More
|
||
|
|
detail about exit programs can be found in <a href="clrgexit.htm">Cluster
|
||
|
|
Resource Group Exit Program</a>.</p>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
|
||
|
|
<li>Clustered Hash Table
|
||
|
|
|
||
|
|
<p>The clustered hash table server enables sharing and replicating
|
||
|
|
non-persistent data between cluster nodes using the Clustered Hash Table APIs.
|
||
|
|
These APIs are described in <a href="clust4a1TOC.htm">Clustered Hash Table
|
||
|
|
APIs</a>.</p>
|
||
|
|
</li>
|
||
|
|
|
||
|
|
|
||
|
|
<li><img src="delta.gif" alt="Start of change">
|
||
|
|
Cluster Administrative Domain
|
||
|
|
|
||
|
|
<p>The cluster administrative domain will allow a consistent operational environment
|
||
|
|
across the cluster or a subset of the cluster through the use of commands and
|
||
|
|
Integrated Operating Environments APIs. These APIs are described in
|
||
|
|
<a href="ss1b.htm">Integrated Operating Environments APIs</a>.<img src="deltaend.gif" alt="End of change"></p>
|
||
|
|
</li>
|
||
|
|
</ol>
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
<p>Nodes in a cluster can have different releases of the operating system
|
||
|
|
installed on them. The function from a newer version of the operating system
|
||
|
|
cannot always be used on nodes that have an older version of the operating
|
||
|
|
system. A cluster version manages this. More information can be found in <a
|
||
|
|
href="clust1a6.htm">Cluster Version</a>.</p>
