The real-time analysis (RTA) function of CICSPlex® SM provides the automatic and external
notification of conditions in which users have expressed an interest. Real-time
analysis may be divided between several sub-components:
- System Availability Monitoring (SAM) - monitors CICS® regions during their planned hours of
availability, and generates notifications when no responses are received from
a region that is expected to be active.
- MAS Resource Monitoring (MRM) - monitors the state of any inquirable CICS
resource, and generates notifications when that state varies from a predetermined
norm.
- Analysis Point Monitoring (APM) - replicates the function of MRM, except
that it analyses states at a CICSplex level, rather than at a specific CICS
region. APM is particularly useful in environments that use cloned AORs, where
regions are identical and one notification is sufficient to alert you to a
general problem.
Clearly SAM is a useful function for reporting the availability of CICS
regions, regardless of whether they are designated listeners or AORs. If you
are executing enterprise beans in a distributed environment, then MRM may
be more useful for monitoring the state of CorbaServers and DJARs, rather
than the region based functions of APM. However, be aware that you cannot
monitor enterprise bean objects themselves (EJCOBEAN and EJDJBEAN) within
RTA. Enterprise bean inquiries may be keyed only on their corresponding CorbaServer
or DJAR names. Specific inquiries may not be made solely on the enterprise
bean name. An overview of the RTA function is given in CICSPlex System Manager Concepts and Planning.
Full detail of the RTA function is given in CICSPlex System Manager Managing Resource Usage.
