The "who" command's interpretation of idle is solely based on terminal activity: "Is there any input coming from the user?" type of activity. Any unix process that does not have terminal i/o will register as idle in the "who" output.

I'm definitely going to use some of them to improve processing. Good news: Universe is not at fault! So why did the process just end? Because a background process we run logs out processes idle for more than 3 hours. To determine idle time we check the 7th column of the output from the unix command "who -HTR". Here was the surprise for me: even though the process was furiously performing I/O, as far as that unix command was concerned, it was idle. Oops! Easy to fix that, of course. The best parts of this were that UniVerse came through as more robust than I had worried it wasn't, and that contributors gave me some great advice. Thanks again to all.

I'd definitely try this same thing with sequential I/O. -K _______________________________________________ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users This e-mail and related attachments and any response may be subject to public disclosure under state law. _______________________________________________ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users -- Message protected by DealerGuard: e-mail anti-virus, anti-spam and content filtering. http://www.pentanasolutions.com Click here to report this message as spam: https://login.mailguard.com.au/report/1xUYc2DuCm/7HvnjYZB2DCQyJk1ZdTcqC/0 _______________________________________________ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users
