All,

I would just like some clarification on a point:

call count cpu elapsed disk query current rows
------- ------ -------- ---------- ---------- ---------- ---------- ----------

Parse        1      0.00       0.00          0          0          0           0
Execute      1      0.00       0.00          0          0          0           0
Fetch       20      1.01      10.85       6171       7395          0         283

------- ------ -------- ---------- ---------- ---------- ---------- ----------
total 22 1.01 10.85 6171 7395 0 283

When the tkprof output shows disk activity of 6171 does this include blocks used in one/multi pass hash joins. Are the direct path reads/writes included ?

Elapsed times include waiting on following events:

  Event waited on                             Times   Max. Wait  Total Waited
  ----------------------------------------   Waited  ----------  ------------
