really interesting ... thanks :-)
The reason I asked is that I had the OS up and running before I started thinking of putting 10g on it. After I read the docs and explored the system I discovered I didn't have enough swap to satisfy oracle. I'm now deciding wether to repartition to give a bigger swap partion or add a swap file.
