Environmental Information
Fields under this heading describe characteristics of the CICS® environment.
- CICS Release
- The CICS version and release.
Transaction Statistics
Some CICS processing statistical values are shown under
this heading.
- First Transaction TaskId
- The value of the CICS TaskId at the beginning of the
observation session.
- Last Transaction TaskId
- The value of the CICS TaskId at the end of the observation
session.
- Number of TaskId Increments
- The difference between the first and last CICS TaskId.
- Number of Observed Transactions
- The number of transactions with unique CICS TaskId
values observed. If this value does not correspond to the number of
increments, it could be an indication that not all executed transactions
were measured. Some transactions could have been excluded as specified
in the measurement request or transactions can be missed if a sampling
rate is chosen that is slower than the transaction throughput rate.
- Transaction Rate
- The average number of transactions per second during the measurement
interval.
- Peak Active Transactions
- The maximum number of concurrently active transactions observed
during the measurement interval.
- Peak Active Txns (Overall)
- The maximum number of concurrently active transactions that
occurred during the entire execution of the CICS region.
- MaxTask
- The maximum number of concurrent transactions CICS is
configured for.
Mean Transaction Time
The average service time for the transactions observed during the
measurement interval.
The service time consists of:
- Execution Time
- The time a CPU is processing the transaction.
- Suspend Time
- The time the transaction is suspended by CICS.
- CICS Dispatch Delay Time
- The time the transaction is delayed by CICS.
- MVS™ Dispatch Delay Time
- The time execution is delayed by the MVS dispatcher.
- Service Time
- The sum of the execution time, the suspend time, and the delay
time.
Service Statistics
These are counts of service requests issued by CICS programs
during the measurement interval:
- Program Requests
- Terminal Messages
- Storage Getmains
- Storage Freemains
- File I/O Requests
- Temporary Storage Requests
- Transient Data Requests
- Journal Write Requests
Exception or Critical Conditions
These are counts of certain exception or critical conditions that
occurred during the measurement interval:
- System Dumps
- System Dumps Suppressed
- Transaction Dumps
- Transaction Dumps Suppressed
- Storage Violations
- Short on Storage occurrences
- Times at MaxTask
- Times at Class MaxTask
Transaction Counts
