Rich, Yes, I'm maybe even tiplenoid (trinoid, trionoid?) or quadranoid. It takes me a long time to do some things with all the backups, pwd's, ll's, env's, etc. that I do to make sure I'm where I think I am. There are risks with our layout, but I think there are risks with any layout. Even with the /u001 - /u016 layout, a former DBA here managed to systematically rm all redologs, arclogs, and rollback segment tablespace files on a Production server, even though they were in way different mount points. He just didn't pay enough attention to which terminal session he was in and thought he was still on the Dev server he'd been working with. No layout can protect you from carelessness, though, granted, some are safer than others. Jack C.

Thus, my preference of the somewhat goofy "orafra", "oractl", etc. naming -- there's less chance of confusion as to what dir one is in or heading to. It's minor, what with prompts being set to include PWD and all (and I colorize mine as well!), but I'm paranoid. And that's twice as bad as being singleoid. :) Rich -- //www.freelists.org/webpage/oracle-l
