Hi Gurus,

I was analyzing the output of 10046 event of a single session. Myself and my fellow coleage differ in the interpretation of the output statistics.

Question 1
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

The output Reads

Elapsed times include waiting on following events:

  Event waited on                             Times   Max. Wait  Total

Waited

Waited ----------
SQL*Net message to client 6 0.00 0.00 SQL*Net message from client 5 132.69 142.99

My Understanding of this output is=20

Times waited -- Number of times this event has waited. Here the user might have entered 7 statements hence it says number of times waited as 6

Max Waited -- Maximum duration of wait (Out of the 6 times it has waited)

Total Waited -- Total Waiting time ( sigma of 6 wait times )

Pls confirm whether my understanding is correct.

Question 2
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Say I turn on the SQL tracing at 12.00 and the session is idle till 1.00 and a single SQL statement is executed at 1.00.

Now if I analyze the ouput.

My undestanding is that, this 1 hour would be accounted in the "SQL*Net message from client" . Is my understanding correct??

Best Regards

Sriram Kumar
