5.3.6.3 Usage Considerations

This section identifies usage considerations and techniques
for accessing the IDMS User Activity File (IDMSUA).

Using the special date and time data elements requires
special care.  As the file's granularity increases in higher
timespans, certain fields lose significance and should not be
used, namely:

o  HOUR should not be used in MONTHS or YEARS.
o  DAY and DAYNAME should not be used in MONTHS or YEARS.
o  WEEK should not be used in MONTHS.

The DURATION data element represents the elapsed time of the
individual transaction records in the IDMSUA file.  In
summarized timespans, DURATION represents the sum of DURATION
of the individual transaction records that contributed to the
summarized observation.  DURATION is calculated as the
difference between the End Time (PMHETIME) and the Start Time
(PMHSTIME) fields from the CA-IDMS Performance Monitor header
record.

In all IDMS Analyzer files except the IDMSIN file, the
STARTTS and ENDTS data elements do not reflect the Start Time
and End Time of the individual transactions.  Instead,
STARTTS and ENDTS are adjusted to represent the start and end
of the time interval within which the transactions executed.
