<h1 class="topictitle1">Resource Monitoring and Control (RMC)</h1>
|
|
<div><p>Resource Monitoring and Control (RMC) is a generalized framework
|
|
for managing, monitoring, and manipulating resources such as physical or logical
|
|
system entities. </p>
|
|
<p>RMC is utilized as a communication mechanism for reporting service events
|
|
to the Hardware Management Console (HMC). If RMC is not active, then service
|
|
events will not be reported to the HMC. The following list describes services
|
|
that are associated with RMC:</p>
|
|
<dl><dt class="dlterm">CAS Daemon</dt>
|
|
<dd><strong>Purpose: </strong> Acts as the authentication server for RMC. </dd>
|
|
<dd class="ddexpand"><strong>Job Name: </strong> QCSTCTCASD</dd>
|
|
<dt class="dlterm">RMC Daemon </dt>
|
|
<dd><strong>Purpose:</strong> Monitors of resources by communicating with the Resources
|
|
Managers. </dd>
|
|
<dd class="ddexpand"><strong>Job Name: </strong> QCSTCTRMCD</dd>
|
|
<dt class="dlterm">SRC Daemon </dt>
|
|
<dd><strong>Purpose:</strong>Monitors the status of the other RMC jobs; it will restart
|
|
a job if that particular job unexpectedly ends.</dd>
|
|
<dd class="ddexpand"><strong>Job Name:</strong> QCSTSRCD</dd>
|
|
</dl>
|
|
<div class="section"><h4 class="sectiontitle">Resource Managers (RM)</h4><div class="p">A Resource Manager (RM) is
|
|
a job that manages and provides the interface between RMC and actual physical
|
|
or logical entities. Although RMC provides the basic abstractions, such as
|
|
resource classes, resources, and attributes for representing physical or logical
|
|
entities, it does not itself represent any actual entities. An RM maps actual
|
|
entities to RMC's abstractions. The following list describes the different
|
|
Resource Managers that are supported for RMC:<dl><dt class="dlterm">Audit Log RM</dt>
|
|
<dd><strong>Purpose: </strong> Provides a facility for recording information about
|
|
the system's operation. </dd>
|
|
<dd class="ddexpand"><strong>Job Name: </strong> QYUSALRMD</dd>
|
|
<dt class="dlterm">CSMAgent RM</dt>
|
|
<dd><strong>Purpose: </strong> Provides resource classes to represent the Management
|
|
Server, which is the HMC.</dd>
|
|
<dd class="ddexpand"><strong>Job Name:</strong> QYUSCMCRMD</dd>
|
|
<dt class="dlterm">Host RM</dt>
|
|
<dd> <strong>Purpose:</strong> Provides resource classes to represent an individual
|
|
machine.</dd>
|
|
<dd class="ddexpand"><strong>Job Name: </strong>QCSTCTHRMD</dd>
|
|
<dt class="dlterm">Service RM</dt>
|
|
<dd><strong>Purpose:</strong> Manages problem information and prepares it for delivery
|
|
to the HMC. </dd>

<div class="section"><h4 class="sectiontitle">Starting or ending the RMC</h4><div class="p"> All RMC jobs, including
|
|
RM jobs are in the QSYSWRK subsystem and are automatically started when the
|
|
subsystem is started. TCP/IP must be active for startup to complete. The
|
|
RMC Daemon requires TCP/IP to be active. If TCP/IP becomes inactive, then
|
|
the RMC Daemon will end. The RMC Daemon will be automatically
|
|
restarted by the SRC Daemon once TCP/IP becomes active again. No steps are
|
|
required of the user under normal conditions. If RMC needs to be manually
|
|
started, run the following command: <pre>SBMJOB CMD(CALL PGM(QSYS/QCSTCTSRCD)) JOBD(QSYS/QCSTSRCD) PRTDEV(*JOBD) OUTQ(*JOBD)
|
|
USER(*JOBD) PRTTXT(*JOBD) RTGDTA(RUNPTY50)</pre>
|
|
</div>
|
|
<p> If RMC needs
|
|
to be manually ended, use the ENDJOB command to end the QCSTSRCD job. This
|
|
command should end all RMC jobs. If all the jobs do not end, then manually
|
|
end each of the jobs listed above. </p>
