Oracle 9i on Unix

i am upgrading my Oracle 8i database to 9i that runs on Unix platform. Does this require me to make any changes in Unix so as to run the upgrade successfully?

You should read the release notes, readme files and installation guide of Oracle 9i software. I wouldn't expect any major changes except for possibly some kernel tweaks.

Obviously, you might want to cater for better hardware. The higher the release version the slower it tends to get on identical hardware!

Thanx...done all that is required but the network is too slow...i hope this relates to hardware upgrade now...i'll let you know of the latest results...
