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
