5.3.4.3 Usage Considerations

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

1.  The following data elements in the SCPENQ 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 SCPENQnn file in the DETAIL timespan.

    ENQFG1   - Enqueue Status Indicator
    ENQJW1ST - Job 1 Wait Status
    ENQJW2ST - Job 2 Wait Status
    ENQJO1ST - Job 1 Owner Status
    ENQJO2ST - Job 2 Owner Status
    ENQCONST - Resource Contention Status
    ENQDO1   - Job Name 1 of Current Resource Owner
    ENQDO2   - Job Name 2 of Current Resource Owner
    ENQDW1   - Job Name 1 Waiting for Resource
    ENQDW2   - Job Name 2 Waiting for Resource
    ENQSCOPE - System Scope Status
    ENQRHEX  - Hex Minor Name Expanded

2.  In some cases the ENQRNM data element provides an
    interpretation of the minor resource field when the field
     is an encoded binary value.

    The ENQRNM data element is built to interpret the ASID
    contained in the minor resource field for the following
    major resource names, so that the ENQRNM element equals
    'ASID=hhhh':

    SYSZIGGI, SYSZTIOT, or SYSSJWTP

    The ENQRNM data element is built to interpret the
    relative block address (RBA) contained in the minor
    resource field for the following major resource names, so
    the ENQRNM element equals 'RBA=hhhhhh':

    SYSIKJBC

    The ENQRNM data element is built to interpret the catalog
    auxiliary work area (CAXWA) contained in the minor
    resource field, for the following major resource names,
    so the ENQRNM element equals 'CAXWA=hhhhhhhh':

    SYSZRPLW, IEZIGGV3, or SYSZCAXW
 
    The ENQRNM data element is built to interpret the unit
    control block address (UCBADDR) contained in the minor
    resource field for the following major resource names so
    that the ENQRNM element equals 'UCBADDR=hhhhhhhh':

    SYSZUSRL or SYSZVMV

     For major resource names other than those specified
    above, hexadecimal and special characters other than . -
    $ are set to blank to alleviate unprintable characters
    being encoded in the ENQRNM field.

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  DAY and DAYNAME should not be used in WEEKS.

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.
