CICS Connections Situations

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
