had done that already and still having a problem.

It's not a crisis situation thankfully. Just curious having this kind of problem on Solaris 9. Guess it's too new for Oracle still. I have also noticed in the alert log something funny:

WARNING: EINVAL creating segment of size 0x000000000f086000
fix shm parameters in /etc/system or equivalent

I have updated the system parameters given Oracle's specs.

All very strange indeed.
