Could you please send the entire raw trace file.

Subject: What do you make of this?
Hi, all. Oracle10g (10.1.0.4.0) on Windows 2000.
I have a set of traces that are puzzling. I had the traces done in
controlled conditions, with a single user on the database; CPU usage on the DB
server was less than 25%. This statement is a good example of what I'm trying
to figure out. There's a high ratio of elapsed to CPU on the parse, but not
much in the way of wait information--except the SQL*Net message from client.
The client is a COM+ application server. No recent changes that I know of on
that machine, nor on the DB server itself. I have inspected the raw trace file
as well and don't see anything to suggest that the tkprof timing summaries are
incorrect.
II'm looking for ideas on how to go about diagnosing the SQL*Net waits
(assuming they're accounting for the different between CPU and elapsed) or
finding where the rest of the elapsed time comes from. Thanks in advance for
any suggestions!
