<div class="section"><h4 class="sectiontitle">Cluster administrative domain support</h4><div class="p">A <dfn class="term">cluster
|
|
administrative domain</dfn> monitors and synchronizes changes to selected
|
|
resources within a cluster. Cluster administrative domain provides easier
|
|
management and synchronization of attributes for resources that are shared
|
|
within a cluster, such as environment variables or user profiles. For more
|
|
information about cluster administrative domain, see these topics:<ul><li><a href="rzaigconceptsclusteradmindmn.htm">Cluster administrative domain</a></li>

<div class="section"><h4 class="sectiontitle">Peer cluster resource group (CRG) support</h4><div class="p">All CRG
|
|
interfaces have been enhanced to support peer cluster resource group (CRG).
|
|
A <dfn class="term">peer cluster resource group (CRG)</dfn> is a non-switchable CRG in
|
|
which each node in the recovery domain has an equal role in the recovery of
|
|
the resources associated with the peer CRG. For more information, see the
|
|
following topics:<ul><li><a href="rzaigconceptscrg.htm">Cluster
|
|
resource group</a></li>

<div class="section"><h4 class="sectiontitle">Cluster enhancements</h4><div class="p">Several enhancements have been
|
|
made to improve powering down operations and problem resolution within a clustered
|
|
environment. These improvements include:<ul><li>A systematic approach to end clustering on a cluster node when all active
|
|
subsystems are ended, or when the system is ended or powered down. See <a href="rzaigpowerdownsys.htm">How a system event affects a cluster</a> for details.</li>
|
|
<li>The capability to configure a new application CRG with an active takeover
|
|
IP address. See <a href="rzaigcreatecrg.htm">Create an application CRG with an active takeover IP address</a> for
|
|
more information.</li>
|
|
<li>The capability to troubleshoot cluster problems by viewing an entire cluster
|
|
and its associated CRGs from an active node. See <a href="rzaigviewclustercrg.htm">Gather recovery information for a cluster</a> for
|
|
more details.</li>
|
|
<li>New information about debug tools and the results they generate has been
|
|
added. You can use these tools and their results to determine the resolution
|
|
of a problem within a cluster. See the following topics for more details:<ul><li><a href="rzaiginvestigatetrace.htm">Investigate a problem with Dump Cluster Trace (DMPCLUTRC) command</a></li>
|
|
<li><a href="rzaiginvestigateclusterinfo.htm">Investigate a problem with CLUSTERINFO macro</a></li>
