Resource Monitoring and Control (RMC) is a generalized framework
for managing, monitoring, and manipulating resources such as physical or logical
system entities.
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:
- CAS Daemon
- Purpose: Acts as the authentication server for RMC.
- Job Name: QCSTCTCASD
- RMC Daemon
- Purpose: Monitors of resources by communicating with the Resources
Managers.
- Job Name: QCSTCTRMCD
- SRC Daemon
- Purpose:Monitors the status of the other RMC jobs; it will restart
a job if that particular job unexpectedly ends.
- Job Name: QCSTSRCD
Resource Managers (RM)
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:
- Audit Log RM
- Purpose: Provides a facility for recording information about
the system's operation.
- Job Name: QYUSALRMD
- CSMAgent RM
- Purpose: Provides resource classes to represent the Management
Server, which is the HMC.
- Job Name: QYUSCMCRMD
- Host RM
- Purpose: Provides resource classes to represent an individual
machine.
- Job Name: QCSTCTHRMD
- Service RM
- Purpose: Manages problem information and prepares it for delivery
to the HMC.
- Job Name: QSVRMSERMD
Starting or ending the RMC
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:
SBMJOB CMD(CALL PGM(QSYS/QCSTCTSRCD)) JOBD(QSYS/QCSTSRCD) PRTDEV(*JOBD) OUTQ(*JOBD)
USER(*JOBD) PRTTXT(*JOBD) RTGDTA(RUNPTY50)
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.
