ANL5019W *** ALERT: PRESENTLY, THE PERCENTAGE OF ROWS ESTIMATED TO BE READ WITH THIS RANDOM INDEX VIA LIST PREFETCH IS APPROACHING 25% OF TOTAL TABLE ROWS. SOON, Db2® WILL CHOOSE TABLESPACE SCAN INSTEAD OF MATCHING THE RANDOM INDEX. RUNSTATS IS RECOMMENDED, INCLUDING THE COLLECTION OF NON-UNIFORM STATISTICS. THIS SHOULD CULMINATE IN BETTER STATS, AND ALLOW Db2 TO CONTINUE TO SELECT THIS PATH.
