Use the series of predefined situations associated with the CICS
Connections workspace to begin monitoring your system immediately or as templates
for creating your own situations.
The names, descriptions, logic, and threshold values for the situations
follow.
KDP_CICT_Critical monitors the percentage of active
CICS threads to THRDMAX, detecting a critical condition when that percentage
reaches 80%. The THRDMAX value is specified in the CICS RCT. The situation's
formula is:
DP _CICS_Exceptions.Total_Thread_Utilizaton GE 80.0
KDP_CICT_Warning monitors
the percentage of active CICS threads to THRDMAX, detecting a warning condition
when that percentage is in the range of 64% to 80%. The THRDMAX value is specified
in the CICS RCT. The situation's formula is:
KDP_CICS_Exceptions.Total_Thread_Utilizaton GE 64.0
AND
KDP_CICS_Exceptions.Total_Thread_Utilizaton LT 80.0
KDP_ENTO_Critical monitors pool thread usage. A critical condition
is detected when the number of POOL threads in use because of ENTRY thread
overflow activity reaches 3 transactions. This situation limits its analysis
to ENTRY definitions that specify TWAIT=POOL and THRDA>0. The situation's
formula is:
KDP_CICS_Threads.Pool_Thread_Overflow GE 3
KDP_ENTO_Warning monitors
pool thread usage. A warning condition is detected when the number of POOL
threads in use because of ENTRY thread overflow activity is in
the range of two to three transactions. This situation limits its analysis
to ENTRY definitions that specify TWAIT=POOL and THRDA>0. The situation's
formula is:
KDP_CICS_Threads.Pool_Thread_Overflow GE 2
AND
KDP_CICS_Threads.Pool_Thread_Overflow LT 3
KDP_ENTU_Critical monitors CICS ENTRY thread usage. The definition
and use of ENTRY threads enables the DB2 user to assign one or more DB2 threads
to a single DB2 plan. It also allows definition of one or more transactions
that may use the plan. A critical condition is detected when the percentage
of active threads that originate from a CICS ENTRY definition to THRDA reaches
95%. The THRDA value is specified in the resource RCT. The situation's formula
is:
KDP_CICS_Threads.Entry_Threads_InUse GE 95
KDP_ENTU_Warning monitors
CICS ENTRY thread usage. The definition and use of ENTRY threads enables the
DB2 user to assign one or more DB2 threads to a single DB2 plan. It also allows
definition of one or more transactions that may use the plan. A warning condition
is detected when the percentage of active threads that originate from a CICS
ENTRY definition to THRDA is in the range of 76% to 95%. The THRDA value is
specified in the resource RCT. The situation's formula is:
KDP_CICS_Threads.Entry_Threads_InUse GE 76
AND
KDP_CICS_Threads.Entry_Threads_InUse LT 95
KDP_ENTW_Critical monitors CICS transactions waiting for ENTRY
threads. A critical condition is detected when the number of CICS transactions
waiting for a thread reaches two transactions. This situation detects transactions
that are waiting, because all threads defined for use in the RCT ENTRY definition
are already in use. This situation limits its analysis to ENTRY definitions
that specify TWAIT=YES. The situation's formula is:
KDP_CICS_Threads.Entry_Thread_Waiting GE 2
KDP_ENTW_Warning monitors CICS transactions waiting for ENTRY threads. A warning condition
is detected when the number of CICS transactions waiting for a thread is in
the range of one to two transactions. This situation detects transactions
that are waiting, because all threads defined for use in the RCT ENTRY definition
are already in use. This situation limits its analysis to ENTRY definitions
that specify TWAIT=YES. The situation's formula is:
KDP_CICS_Threads.Entry_Thread_Waiting GE 1
AND
KDP_CICS_Threads.Entry_Thread_Waiting LT 2
KDP_POLU_Critical monitors the percentage of pool threads
in use. A critical condition is detected when the percentage of active CICS
POOL threads to THRDA reaches 90%. The THRDA value is specified in the resource
control table (RCT). The situation's formula is:
KDP_CICS_Exceptions.Pool_Threads_Inuse GE 90
KDP_POLU_Warning monitors the percentage of pool threads in use. A warning condition is detected
when the percentage of active CICS POOL threads to THRDA is in the range of
72% to 90%. The THRDA value is specified in the resource control table (RCT).
The situation's formula is:
KDP_CICS_Exceptions.Pool_Threads_Inuse GE 72
AND
KDP_CICS_Exceptions.Pool_Threads_Inuse LT 90
KDP_POLW_Critical monitors the number of CICS transactions
waiting for a POOL thread that originates from a CICS connection. A critical
condition is detected when the number of CICS transactions waiting reaches
two transactions. The situation's formula is:
KDP_CICS_Exceptions.Pool_Thread_Waits GE 2
KDP_POLW_Warning monitors
the number of CICS transactions waiting for a POOL thread that originates
from a CICS connection. A warning condition is detected when the number of
CICS transactions waiting is in the range of one to two transactions. The
situation's formula is:
KDP_CICS_Exceptions.Pool_Thread_Waits GE 1
AND
KDP_CICS_Exceptions.Pool_Thread_Waits LT 2
