Hi Kirti: THe algorithm is slightly differnt in 9i. In 8i SMON queries the dictionary (dba_tab_modifications) in once in 3 hours to get the stale stats, and then the stats are flushed to the dictionary from the SGA and the dictionary is updated . The operation is reverse in 9i. THe stats are written to dictionary from SGA once in 15 minutes and then the tables are examined to get the stale stats.
