INTENDED USAGE:
The IDMS Calendar Report provides, on a daily basis, an
updated view of key elements which are factors in judging
the performance and effectiveness of the IDMS systems
currently in use. From this report you can track the
current month's utilization of IDMS.
FORMAT:
The report is produced by the SAS Calendar procedure. A
report will be produced for each IDMSID processed
month-to-date within this unit. Since the current daily
cycle is updated, the calendar will reflect up to one full
month's activity. This report makes key indicators
available to assist you in simple daily tracking of IDMS
performance.
A sample of the IDMS Calendar Report is presented in
Figure 3-4.
DATABASE FILE USED:
IDMSCL01 at the DAYS timespan. This is the special data
set which is updated to contain month-to-date information.
DATA ELEMENTS USED:
SCLTTRAN - Total transactions for a given day
SCLABNDS - Total transactions ABENDed for a given day
SCLDBCLS - Total database calls issued for a given day
SCLCPUTM - Calculated total of system and user CPU time,
in seconds
SCLAVTTM - Overall average response time for a given day
SCLAVPIO - Average physical I/O issued per task for a
given day
SCLAVDBC - Average database calls issued per task for a
given day
SCLAVTIO - Average terminal I/O issued per task for a
given day
REPORT LABELS USED:
SCLTTRAN - Shown as TRANS in each day's block
SCLABNDS - Shown as ABENDS in each day's block
SCLDBCLS - Shown as DB CLS in each day's block
SCLCPUTM - Shown as CPU SEC in each day's block
SCLAVTTM - Shown as RSP SEC in each day's block
SCLAVPIO - Shown as AVG PIO in each day's block
SCLAVDBC - Shown as AVG DBC in each day's block
SCLAVTIO - Shown as AVG TIO in each day's block
CALCULATIONS USED:
Total CPU time used expressed in seconds, CPU SEC, is
maintained in the element SCLCPUTM and is the sum of
system and user CPU times:
SCLCPUTM = SCLSYSTM + SCLUSRTM
Average physical I/O requests per task, AVG PIO, is
maintained in the element SCLAVPIO as the sum of pages
read plus pages written divided by the total number of
transactions executed:
SCLAVPIO = (SCLPREAD + SCLPWRIT) / SCLTTRAN
Average database calls per task, AVG DBC, is maintained
in the element SCLAVDBC as the number of database calls
issued per day divided by the total number of transactions
executed:
SCLAVDBC = SCLDBCLS / SCLTTRAN
Average terminal I/O requests per task, AVG TIO, is
maintained in the element SCLAVTIO as the sum of terminal
read plus terminal write requests divided by the total
number of transactions executed:
SCLAVTIO = (SCLTREAD + SCLTWRIT) / SCLTTRAN
USAGE CONSIDERATIONS:
This report is produced as part of the execution of the
normal daily update job standard report step DAY400. No
special options are necessary to produce this report.
IDMS Standard Report Options have no impact on the
generation or selection criteria used to produce this
report.
The calendar report provides key indicators for daily
performance evaluation and short-term trending analysis.
By viewing the calendar produced for each Central Version
system defined, you can judge the major resource
utilization factors that are essential to the performance
of the IDMS system.
These are the more critical factors which need to be
reviewed to obtain a clear picture of what might be
happening within each Central Version; they are not all of
the factors. The elements shown typically change during
growth times or heavy-degradation periods. By keeping a
month-to-date running file, you can perform short-term
trending of the IDMS systems showing peaks, valleys, and
possible growth times. Although the calendar is only
showing the current month's data, the file contains data
from the past three months.
