Please explain this. How is it better to have the archived redo logs on RAID 0 than RAID 5? Surely if you loose the RAID 0 disk that you put your logs on, you also can't recover? What is the difference? Wouldn't it be better to put the logs on RAID 5 to improve their availability? (Or on a mirror if you can afford it)? Received on Fri May 31 1996 - 00:00:00 CEST
