6.2.2.2 Add File in a Timespan

To add a file to a timespan, do the following:
 
    - Review the key structure of the file in the component's
      sharedprefix.MICS.GENLIB member to insure that
      enabling the file in the timespan will produce a
      properly-keyed file.
 
    - Change the FILE statement in the component definition
      in the component's sharedprefix.MICS.GENLIB member
      to reflect the fact.  The "N" in that timespan's
      position must be changed to a "Y".
 
    - Run the cccCGEN to regenerate the component from the
      modified component generator statements.  This job
      will change the component's executable code in the
      sharedprefix.MICS.SOURCE library, and all database
      units in which the component is installed will be
      affected.
 
    - Run the COPYLIBU job for each unit that the component
      is installed in.
 
    - Verify that the number of cycles to be retained in each
      FILE statement in prefix.MICS.PARMS(DBMODEL) suits your
      installation's standards.
 
    - Run the CYCLEGEN job for all database units in which
      the component is installed.  This will generate aging
      statements that reflect the new file configuration.
