We also ran into the IO error situation on a few of our 9i R2 databases using TEMPfiles.
DBAs forgot that the file system contained those tempfiles and created other datafiles on those.
We are now considering using dedicated file system naming convention that will hold TEMPfiles. We
already have /u888, and /u999 for dump dirs and archive logs respectively. Now /u777 for tempfiles
is under review.
