We have an IBM 3HDD W2K server on RAID0. On Disk 1 has windows OS and Oracle OS. I want to config the oracle files as following:

Disk1: controlfile1, REDO files(1,2,3), datafile1, indexfile1
Disk2: controlfile2, UNDOTBS, datafile2, indexfile2
Disk3: controlfile3, TEMP tablespace, datafile3, indexfile3

Is this a good config? RAID level can not be modified or server reconfigured. Each HDD is 18G but space is not an issue. We are running 9.2.0.4.
