I really should take a look at 9i one of these days -- but pay attention: the default install of 8i at least on any Unix-like system can pretty much be considered a misconfiguration by itself. What needs to be changed:
- default block sizes
- memory allocation parameters
... at the very least. Also the default tablespace storage parameters could be improved.
