5.3.1.3 Usage Considerations

Special considerations or techniques related to using the
SCPPAG file are provided below.

1.  The following data elements in the SCPPAG file have
    meaning only in the DETAIL timespan; they lose
    significance once summarization has been performed.
    These data elements should only be referenced when using
    the SCPPAGnn file in the DETAIL timespan.

    CYCLETM  - Sampling Time Cycle Length
    PAGOPT   - SRM OPT Member
    PAGOLE   - On-Line Frames In Expanded Storage
    PAGCF    - Installed Frames In Expanded Storage

2.  Four data elements are maintained for each measure that
    requires a minimum, average, and maximum value.  For
    example, in addition to PAGLS (LSQA Fixed Frames), the
    data elements PAGAVLS, PAGMNLS, and PAGMXLS also measure
    average, minimum, and maximum LSQA Fixed Frames.  The
    PAGLS data element should not be referenced because it is
    a running sum of all values summarized; the PAGAVLS data
    element should be used instead.  When a data element is
    carried as a running total of the average, minimum, and
    maximum values, the average should be used instead of the
    running count.  The MIN/MAX/AVG data element section
    should always be searched ahead of the ACCUMULATED data
    elements to identify the data element to be used.

3.  Care must be exercised in using the special date and time
    data elements contained in each CA MICS file. As the
    file's granularity increases in higher timespans, certain
    fields lose significance; they should not be used in
    those cases.

    o  HOUR should not be used in MONTHS.
    o  DAY and DAYNAME should not be used in WEEKS, MONTHS.
    o  WEEK should not be used in MONTHS.

4.  ENDTS and STARTTS, when appearing in the DAYS, WEEKS, or
    MONTHS timespans, bound the span of time over which the
    data has been summarized.  STARTTS is the lowest date and
    time, and ENDTS is the highest date and time for the data
    summarized.  These data elements have different meanings
    when used in the DETAIL timespan versus the DAYS, WEEKS,
    and MONTHS timespans.   Their purpose in DETAIL is
    described below:

    o  STARTTS represents RMF recording interval start time.
    o  ENDTS represents RMF recording interval end time.
