CICS Connections Situations

OMEGAMON XE for DB2 on z/OS includes a series of predefined situations associated with the CICS Connections workspace. You can use these situations to begin monitoring almost immediately, or as templates for creating your own situations. All of the predefined situations are disabled when shipped.

The names, descriptions, logic, and threshold values for the situations follow.

DP_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

DP_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:

DP_CICS_Exceptions.Total_Thread_Utilizaton GE 64.0
AND
DP_CICS_Exceptions.Total_Thread_Utilizaton LT 80.0

DP_ENTO_Critical monitors pool thread usage. A critical condition is detected when the number of POOL threads in use due to 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:

DP_CICS_Threads.Pool_Thread_Overflow GE 3

DP_ENTO_Warning monitors pool thread usage. A warning condition is detected when the number of POOL threads in use due to 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:

DP_CICS_Threads.Pool_Thread_Overflow GE 2
AND
DP_CICS_Threads.Pool_Thread_Overflow LT 3

DP_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:

DP_CICS_Threads.Entry_Threads_InUse GE 95

DP_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:

DP_CICS_Threads.Entry_Threads_InUse GE 76
AND
DP_CICS_Threads.Entry_Threads_InUse LT 95

DP_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:

DP_CICS_Threads.Entry_Thread_Waiting GE 2

DP_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:

DP_CICS_Threads.Entry_Thread_Waiting GE 1
AND
DP_CICS_Threads.Entry_Thread_Waiting LT 2

DP_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:

DP_CICS_Exceptions.Pool_Threads_Inuse GE 90

DP_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:

DP_CICS_Exceptions.Pool_Threads_Inuse GE 72
AND
DP_CICS_Exceptions.Pool_Threads_Inuse LT 90

DP_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:

DP_CICS_Exceptions.Pool_Thread_Waits GE 2

DP_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:

DP_CICS_Exceptions.Pool_Thread_Waits GE 1
AND
DP_CICS_Exceptions.Pool_Thread_Waits LT 2
