Hi again ;-)

You're right, in Oracle 9i+ that "view" shows you useful data :

DBA_TEMP_FILES Information about database temp files

(you can probably get all similar views by using DICTIONARY or DICT as in select * from dict where table_name like 'DBA%' )

If you want to analyse statistics on a given table or SELECT , then try out dbms_xplan :

analyze table toto compute statistics; delete from plan_table; explain plan for select deptno, count(*) from toto group by deptno; select * from table( dbms_xplan.display );



Don't forget also to try tkprof or v$sql_plan, the setting TIMED_STATISTICS in init.ora or the system view V$SYSSTAT. All may be relevant & helpful depending on your real problem.
