Guys,
When shd I believe in going for gather stats other than the response of the queries is slow?
Is there any table which shows me I shd go for gather stats of a particular table ?
Thanks

In 10.2 statistics are automatically calculated (unless you disabled the job).
You can test with the following script:
set serveroutput on size 10000 format wrapped
declare
l_objList dbms_stats.objectTab;
begin
dbms_stats.gather_schema_stats
( ownname => user,
options => 'LIST STALE',
objlist => l_objList );
for i in 1..l_objList.count loop
dbms_output.put_line (l_objList(i).objName||' - '||l_objList(i).objType);
end loop;
end;
/
Regards
Michel
