10.1.1 Alter Derived Element Support

Derived elements, such as averages and percentages, can
either be kept in the data base or computed when the data is
required for reporting.  Computing these elements only when
needed can reduce the amount of DASD required for the data
base.

CA MICS provides a global option for derived element support
in sharedprefix.MICS.PARMS(CPLXDEF).  This option applies to
all files in the CA MICS Data Base. You can override this
option at the product level or at the file level.  For
example, you may wish to compute data elements at reporting
time for the CICS Analyzer, but keep the computed data
elements for all other CA MICS products in the data base. Or,
you may wish to compute data elements for the CICS User
Activity File at reporting time, but keep the computed data
elements in the CA MICS Data Base for the rest of the CICS
files.

Follow the checklist below to override the options in
sharedprefix.MICS.PARMS(CPLXDEF).

___ 1.  Save a copy of sharedprefix.MICS.GENLIB(CICGENIN) in
        sharedprefix.MICS.LOCALMOD.CNTL for recovery
        purposes.

___ 2.  To override derived element support at the product
        level, review the description of the COMPOPT
        statement in sharedprefix.MICS.GENLIB(CICGENIN)
        provided by Section 4.2.4.1.3 of the System
        Modification Guide (SMG).  To override the option at
        the file level, review the description of the FOPT
        statement in sharedprefix.MICS.GENLIB(CICGENIN)
        provided by Section 4.2.4.2.2 of the SMG.

___ 3.  Update the COMPOPT and/or FOPT statements in
        sharedprefix.MICS.GENLIB(CICGENIN).  Use IEBUPDTE to
        apply the change.

___ 4.  Regenerate the CICS Analyzer by submitting the job in
        sharedprefix.MICS.CNTL(CICCGEN).
