CICS Service Time

The CICS Service Time report provides information about all transactions observed during the measurement period, including the location and amounts of service time. All values reported are based on total time and count activity collected by Strobe. The report further identifies transactions by terminal and by user. Click on the tabs to view statistics for the report.

Report details

CICS Service Time Summary tab

Total Transaction Count shows the total number of transactions for the profile.
Total Change TCB Modes shows the total number of times that the transaction was swapped between CICS kernel TCBs (for example, QR to L8, L8 to QR, etc.). A CICS task always starts and ends on the QR TCB and, depending on transaction definition and EXEC CICS calls, can be re-dispatched on another CICS TCB.
Overall Change TCB Service Time % shows the overall percentage of the total service time spent swapping between CICS kernel TCBs.
Overall Change TCB Mean Service Time (sec) shows the overall average service time spent swapping between CICS kernel TCBs.
Mean Service Time (sec): Delay shows the dispatch delay time of the module name or command.
Mean Service Time (sec): Suspend shows the suspend time of the transaction, module, command, or resource.
Mean Service Time (sec): Exec shows the execution time of the transaction, module, command, or resource.
Mean service time (sec): Total shows the total time of the transaction.

CICS Service Time Transaction tab

Transaction shows the name of the transaction.
Count shows the number of times this transaction passed through the CICS address space over the duration of the measurement.
Observed Count shows the number of times this transaction was sampled over the duration of the measurement.
CPU% shows the percent of CPU time used by the transaction.
Change TCB Modes shows the number of times that the transaction was swapped between CICS kernel TCBs (for example, QR to L8, L8 to QR, etc.). A CICS task always starts and ends on the QR TCB and, depending on transaction definition and EXEC CICS calls, can be re-dispatched on another CICS TCB.
Change TCB Service Time % shows the percentage of the total service time spent swapping between CICS kernel TCBs.
Change TCB Mean Service Time (sec) shows the average service time spent swapping between CICS kernel TCBs.
Mean Service Time (sec): Delay shows the dispatch delay time of the module name or command.
Mean Service Time (sec): Suspend shows the suspend time of the transaction, module, command, or resource.
Mean Service Time (sec): Exec shows the execution time of the transaction, module, command, or resource.
Mean service time (sec): Total shows the total time of the transaction.
Margin of Error shows the margin of error for the transaction.

Terminal shows the name of the module.
Count shows the count number.
CPU% shows the percent of CPU time used by the transaction.
Change TCB Modes shows the number of times that the transaction was swapped between CICS kernel TCBs (for example, QR to L8, L8 to QR, etc.). A CICS task always starts and ends on the QR TCB and, depending on transaction definition and EXEC CICS calls, can be re-dispatched on another CICS TCB.
Change TCB Service Time % shows the percentage of the total service time spent swapping between CICS kernel TCBs.
Change TCB Mean Service Time (sec) shows the average service time spent swapping between CICS kernel TCBs.
Mean Service Time (sec): Delay shows the dispatch delay time of the module name or command.
Mean Service Time (sec): Suspend shows the suspend time of the transaction, module, command, or resource.
Mean Service Time (sec): Exec shows the execution time of the transaction, module, command, or resource.
Mean service time (sec): Total shows the total time of the transaction.
Margin of Error shows the margin of error for the transaction.

CICS Service Time User tab

User ID shows the user ID.
Count shows the count number.
CPU% shows the percent of CPU time used by the transaction.
Change TCB Modes shows the number of times that the transaction was swapped between CICS kernel TCBs (for example, QR to L8, L8 to QR, etc.). A CICS task always starts and ends on the QR TCB and, depending on transaction definition and EXEC CICS calls, can be re-dispatched on another CICS TCB.
Change TCB Service Time % shows the percentage of the total service time spent swapping between CICS kernel TCBs.
Change TCB Mean Service Time (sec) shows the average service time spent swapping between CICS kernel TCBs.
