A.2 File Tailoring for the SPECIAL Database

One advantage of the CA MICS SPECIAL database is the ability
to tailor component files at will.  Normal component file
tailoring affects the entire database complex.  Adding or
deleting a file from a timespan will affect the ability of
CA MICS to contain data in all database units in which the
component appears.

The SPECIAL database gives the CA MICS user the ability to
add files to a timespan, drop files from a timespan, or vary
the number of cycles within a file and within a timespan.

This is accomplished by user specifications in a parameter
library member called SELFILES.  A job called SELFILES reads
this parameter set, and creates executable code to tailor
files in the next database run.

Reconfiguring the SPECIAL database by running the SELFILES
job is typically done between database unit generation and
input processing.  The user may tailor files after unit
installation, but tailoring is typically not done before each
daily run.

The following topics are covered in this section:

1 - SPECIAL Database File Tailoring Options (SELFILES)
