hi#..

i think your Snapshot Collection is turn off.

you can execute this procedure...(one hour snapshot collection)

SQL> exec DBMS_WORKLOAD_REPOSITORY.MODIFY_SNAPSHOT_SETTINGS(10080,60);

PL/SQL procedure successfully completed.


and

also set/CHECK your parameter file statistics_level = "TYPICAL" or "ALL"

WITH REGARDS..
