stange table as in a previous paragragh they write :
"The database is sensitive to read/write performance of the Redo Logs
and should be on a RAID 1 , RAID 0+1 or no RAID at all since they are accessed
sequentially and performance is enhanced in their case by having the disk drive
head near the last write location. "
unless your disk is dedicated to the one database redo log ...
