My bad.
I should also have posted the 10046 trace. I did a 10046 trace and also a
STATSPACK report. Of the total time, more than 50% of the time is spent
waiting on DIRECT PATH WRITE and around 40% of the time it waits on
DIRECT PATH READ. This is what prompted me to do a truss and see what it

A more comprehensive solution would be statspack.
A simpler solution would be to get the sum of wait time (not counting the
idle ones) . it could provide you with some measure of database
performance... You need to arrive at a baseline wait time as being normal

Why would you want to do that - convert two dates into a char and then
compare them ? This is not a problem but it is how char comparisions work.
They are compared char by char to see which one is greater on the ASCII
chart.

What does this wait event
mean? I have a process that connects to the database through ODBC and this
process is waiting on this event and SQL*Net message from client.
Often this process waits for

are considered idle.
