hi all,

Operating System: windows 2000 advanced server.
Oracle: 9.0.1.

does having a one partition hard disk affect Oracle's performance?
i'm planning to have 2 hard disks in every Database server (for multiplexing), but i want to have one partition in every hard disk, because i don't want to be concerned in case of 2 or more partitions about the primary partition getting full, and having to delete some files.
one other thing concerning having 2 hard disks in every database server, what is the best method for placing my tablespaces? do i place the data tablespace in one partition and the temp tablespace in the other? (i like this idea), and what about the index and the undo tablespaces?

Thanks in advance.
