<div><p>A <dfn class="term">cluster resource group exit program</dfn> is called after
|
||
|
|
a cluster-related event for a CRG occurs.</p>
|
||
|
|
<div class="p"><img src="./delta.gif" alt="Start of change" />The exit program is optional for a resilient device CRG
|
||
|
|
but is required for the other CRG types. When a cluster resource group exit
|
||
|
|
program is used, it is called on the occurrence of cluster-wide events, including
|
||
|
|
when:<ul><li>A node leaves the cluster unexpectedly.</li>
|
||
|
|
<li>A node leaves the cluster as a result of the <a href="../apis/clcntendcn.htm"><span class="apiname">End Cluster Node (QcstEndClusterNode)</span> API </a> or <a href="../apis/clcntrmvcne.htm"><span class="apiname">Remove
|
||
|
|
Cluster Node Entry (QcstRemoveClusterNodeEntry)</span> API.</a></li>
|
||
|
|
<li>The cluster is deleted as a result of the <a href="../apis/clcntdltc.htm"><span class="apiname">Delete Cluster (QcstDeleteCluster)</span> API.</a></li>
|
||
|
|
<li>A node is activated by the <a href="../apis/clcntstcn.htm"><span class="apiname">Start Cluster Node (QcstStartClusterNode)</span> API.</a></li>
|
||
|
|
<li>Communication with a partitioned node is re-established.</li>
|
||
|
|
</ul>
|
||
|
|
<img src="./deltaend.gif" alt="End of change" /></div>
|
||
|
|
<p>Exit programs are written or provided by cluster middleware IBM Business
|
||
|
|
Partners and by cluster-aware application program providers.</p>
|
||
|
|
<p>For detailed information on the cluster resource group exit programs, including
|
||
|

what information is passed to them for each action code, see <a href="../apis/clrgexit.htm">Cluster Resource Group Exit Program</a> in
