 __  1. Determine your complex level setting by viewing
        'sharedprefix.MICS.PARMS(CPLXDEF)'.  This will help
        you determine if you need to set (or override) the
        CKPTLIMIT setting for this unit.
 
   ***********************************************************
   *  Repeat the steps below for each unit database where    *
   *  you want to enable the Checkpoint Cleanup option.      *
   ***********************************************************
 
 __  2. Determine the current setting for the unit by viewing
        'prefix.MICS.USER.SOURCE($BASMSTR)'.  Review the
 
        '%LET CKPTLMT = '
 
        statement.  This will help you determine if you need
        to modify the prefix.MICS.PARMS(SITE) CKPTLIMIT
        setting for this unit.
 
 __  3. To enable the Checkpoint Cleanup option
        at the unit level, edit 
 
        prefix.MICS.PARMS(SITE) to insert or modify
        statement:
 
         CKPTLIMIT nnn
 
        where nnn is a value from 1 - 999.

 *** Setting too low a value for the CKPTLIMIT option can  ***
 *** lead to duplicate data if previously processed data   ***
 *** is erroneously presented to the CA MICS update jobs.  ***
 *** Set the value high enough to prevent duplicate        ***
 *** data, but low enough so that a benefit is gained      ***
 *** that can offset the overhead of the DAILY "age"       ***
 *** checking.  For example, a value of 120 would remove   ***
 *** any entries OLDER than 120 days from the current      ***
 *** run date, of the CA MICS DAILY job.                   ***
 ***                    W A R N I N G                      ***

 __  4. Submit the following job:
 
        'prefix.MICS.CNTL(BASPGEN)'
 
        Ensure that there are no error messages in the MICSLOG
        or SYSTSPRT.  Review the MICSLOG for BAS00196I message
        pertaining to the CHECKPOINT Option status.  Ensure
        the MICSLOG contains the BAS00433I message as well as
        the normal termination message, BAS60199I, and that
        the job completes with a condition code of zero.

   *  Repeat these steps for each unit database where        *
   *  you want to enable the Checkpoint Cleanup option.      *
