  • Date: Tue, 31 Jan 2006 16:14:41 -0500, 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

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.
