I *think* (not sure here) that the only exception to that is the time that gets logged to the event named "single-task message".

Thanks Tom,

I never knew that. Amazing how one can work with totally false assumptions
for years and never have them trip you up until you expose your ignorance to
the whole world :).

Thanks!

Jay

Jay,

from what I remember, *all* connections go thru SqlNet - even those that reside on the server. Oracle made this change a few years back (actually,
quite a few years back) in preparing themselves for the internet world. and
also so that a new release of the database does not require a complete re-compile of everything.

A developer/analyst was running 4 reports on our datawarehouse, connecting
locally using SQL Plus from a telnet session on the Unix box. He then started 4 queries, spooling the output to the unix server (again, local).

He was curious as to why the sessions were both taking so long and why they
alternated between showing as Active and Inactive in v$session.

When I checked v$session_wait for his sessions I saw that they were a mix of
SQL*Net message from client and
SQL*Net message to client

Since he's not connecting through the listener, why would this wait event
show up? There should be no network activity at all (I double checked that
the SQL is not using any database links). Any ideas?

Oracle 8.1.6.2
Solaris 2.6

Thanks,
Jay Miller
