System Status Components and Related Exceptions
System Status Components and Related Exceptions
OMEGAMON II monitors your DB2 subsystem by comparing the performance of your
subsystem against a set of performance standards. These standards are called thresholds.
When the performance of a workload or a resource exceeds a threshold, an exception
condition occurs.
The status indicators on the System Status panel summarize the status of the thresholds
that you set in OMEGAMON. When OMEGAMON detects that a threshold has been
exceeded, the status indicators for all panels that report on that threshold are affected,
including the System Status panel.
The following tables are a quick reference to the exceptions that affect the status indicators
for components on the System Status panel.
CICS exceptions
The following exceptions apply to threads related to CICS connections.
Description Code Explanation
Available pool thread % POLU The percentage of active CICS POOL threads to THRDA
exceeds the specified threshold. The THRDA value is
specified in the CICS resource control table (RCT).
CICS threadmax % CICT The percentage of active CICS threads to THRDMAX
exceeds the specified threshold. The THRDMAX value is
specified in the CICS RCT.
CICS transaction
waiting ENTW The number of CICS transactions waiting for a thread
exceeds the specified threshold. This exception detects
transactions that are waiting, because all threads defined for
use in the RCT ENTRY definition are already in use. This
exception limits its analysis to ENTRY definitions that
specify TWAIT=YES.
ENTRY thread % ENTU The percentage of active threads that originate from a CICS
ENTRY definition to THRDA exceeds the specified
threshold. The THRDA value is specified in the resource
RCT.
Pool overflow threads ENTO The number of POOL threads in use due to ENTRY thread
overflow activity exceeds the specified threshold. This
exception limits its analysis to ENTRY definitions that
specify TWAIT=POOL and THRDA>0.
Pool thread waits POLW The number of CICS transactions waiting for a POOL
thread that originates from a CICS connection exceeds the
specified threshold.
