Thanks. I'll let you know how it goes.

I had issues with tnsping and found missing brackets or brakets were not placed properly. It was a Linux server with 9206 database. It was just taking forever and consuming all memory. After running trace we observed this issue.

Added to try to diagnose another problem. About the time the exports started running slow. TRACE_LEVEL_CLIENT=16 TRACE_DIRECTORY_CLIENT=/oracle_rdbms/app/oracle/product/8.1.7/network/trace TRACE_TIMESTAMP_CLIENT = ON TNSPING works well.

May be any bracket is missing or format error. How about your tnsping to that database work from local server?

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. Thanks!

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? -Mark -- Mark J.

Ran 8.5 hours this time. V$Session_Wait looks low right now. I have never used the Truss command.
