Determining hardware requirements for upgrade to 9i

If you are using Oracle 8 or 8i and you upgrade the database to 9i and you do not change any INIT.ORA parameters, then you do not need any additional hardware requirements to run this database. Upgrading the database does not require more memory or CPU. But you may wish to take advantage of some new features of 9i, and that may require more memory.

The bottom line is, as long as you just upgrade to 9i and don't change your database configuration, then what you have working now, will work after the upgrade.
