No, I found I can run truss. Just don't know how since we usually can't run those type utilities.
The only waits are SQL*NET waits, to and from the client. About 350 but no time associated with the wait.
The export is local. If done remotely the export runs much faster, back to normal times.

Hmm....so, they explicitly deperm access to the truss binary? On most Sun servers, it's in /usr/bin, and you should not need root permission to truss an oracle owned process. If you can login as the user who started the database (presumably oracle), that should be good enough to do the trace. Unless they really do explicitly deperm the binary. If that's true, I'd argue that's a battle you need to fight, in order to do you job well, you need access to O/S level tools like truss. (I know, I know, easier said than done....;-))

As for the V$SESSION_WAIT output, what do you mean by "looks low"? Are you seeing waits? What are they?

Also, regarding Tanel's last question, are you exporting locally, or over the network?

I had to restart the export. Ran 8.5 hours this time.
V$Session_Wait looks low right now.
I have never used the Truss command. Unix admins don't give us access.

Are you exporting over network or locally in the server?

V$SESSION_EVENT, V$SESSION_WAIT and truss -c should sufficient to reveal the cause..

There are several exports in different databases, exporting various size objects. The thing is, this started about the middle of December.
Before that, everything was fine.
