Subj:   Re: Set Tables with UPI
 
From:   Geoffrey Rommel

  The database checks the index for uniqueness rather than the entire row. Without it, each new row needs to be checked against every existing row.  


Au contraire ... each new row needs to be checked only against other rows with the same PI value; therefore, this check takes place on only one AMP.
