I am running 9.2 on my machine. The installation manual for 9i says the max
open files should be set to 65536. I think you'll find that you cannot
increase it beyond 1024 unless you are logged on under root. You may be
able to modify this via some kernel parameter, but I don't know. I went a
different route. I set up a start-up script under root and execute it via a
su -C from my regular user account. The script issues two ulimit commands,
starts Oracle, then comes back to my regular session. The two ulimit
commands are --
ulimit -n 65536 <-max open files
ulimit -u 16384 <-max processes per user
These limits are as per the instructions in the Oracle 9i Installation Guide
under Pre-Installation Requirements (page 2-21).
