BATCH TOTAL
_____ _____ 392 22 0.05 22310 20983The meaning of the various fields in the report is as follows:
- TRACE START and TRACE STOP
- The trace start and trace stop fields tell you the time when the
DB Monitor program was last started and stopped. The time is generated
by the time-of-day-clock. Clock times are read as follows:
where:Clock time = hh.mm.ss- hh
- Hours 0 through 23
- mm
- Minutes
- ss
- Seconds
If the DB Monitor was on during an entire batch run, the trace start and trace stop time is when the batch run started and stopped. If the DB Monitor was turned on and off more than once in the same batch run, the trace start and trace stop times are when the monitor was last started and stopped.
- PCBNAME
- This field describes the name of the PCB the report is providing information about. Remember that each application program has one or more PCBs. If PCB names are unique to application programs, this field can only be used to identify which application program the report is providing information about.
- CALL FUNC
- This field describes the type of DL/I call the application program issued.
- LEV NO.
- This field describes the level that was accessed in the hierarchy of the database record to perform the DL/I call. If this field contain zeros, it means position was not established and therefore no level was set. This generally happens when a DL/I call cannot be processed for some reason.
- SEGMENT
- This field describes the 8-character name of the segment accessed by the DL/I call.
- STAT CODE
- This field describes the status code returned after the call (if the status code was not blank).
- DL/I Calls
- This field describes how many times this particular DL/I call was issued and had the five unique characteristics listed in the previous five columns.
- IWAITS
- This field describes the number of times IMS was inactive.
- IWAITS/CALL
- This field describes, by DL/I call, the average number of times IMS was inactive.
- ELAPSED TIME
- This field describes, by DL/I call, the elapsed time for calls.
- MEAN
- The average elapsed time per DL/I call
- MAXIMUM
- The longest elapsed time for a single DL/I call
- NOT IWAIT TIME
- This field describes, by DL/I call, the elapsed time minus the
IWAIT time.
- MEAN
- The average NOT IWAIT TIME
- MAXIMUM
- The longest single NOT IWAIT TIME
NOT IWAIT TIME includes any time spent by higher priority tasks running in the IMS region. NOT IWAIT TIME might be about equal to total processor time if the IMS database region is the high priority task and no low priority tasks are causing interrupts.
- DISTRIB.NUMBER
- The distribution number is a reference number to be used in conjunction with the Distribution-Appendix report. For a description of what it means, see Distribution-Appendix report.
- C, A, and B
- These letters over the IWAITS/CALL, ELAPSED TIME, and NOT IWAIT TIME columns are reference letters to be used in conjunction with the Distribution-Appendix report. For a description, see Distribution-Appendix report.
- BATCH Total
- For this execution of the DB Monitor this field describes:
- DL/I Calls
- The total number of DL/I calls
- IWAITS
- The total number of times IMS was inactive
- IWAITS/CALL
- The average number of IWAITS per DL/I call
