Jon,
well your script also gives me the same busy file. and I am showing the physical reads
also, see my script below. I can see from my script, the same busy data file as I see
from yours, it is just that I have to compare the 2 figures, that is f.phyrds,
f.phywrts. From my script I get :-
/u01/app/oracle/product/8.1.5/dbs/oradata/orcl815/users01.dbf 995671 14940
/u01/app/oracle/product/8.1.5/dbs/oradata/orcl815/system01.dbf 116510 271329
which shows the order of busy from least to the max. and the difference between the 2
f.phyrds, f.phywrts, shows me.
>From your script I get:-

1002657 71.61
/u01/app/oracle/product/8.1.5/dbs/oradata/orcl815/system01.dbf
387046 27.64
So I think I am okay then???
rgds,
raja
