Kevin,

Oracle recommends placing the different members of each group on different disks. This will allow the instance to keep running if you lose a disk. If all members are on one disk and you lose the disk you have lost all of the redo for that group.

Hi all,

    I am testing out Spotlight on Oracle from Quest Software. It is telling me
that my log writer process is slow. What it looks like it is saying is that most disks take about 20ms to right the data and mine is taking on average about 40ms. I don't know why, they are scsi drives and there isn't that much stress on the syste. Anyway, I moved the redo logs to seperate disks, but I fear I may have made an error. Instead of moving each "group" to seperate hard disks, I moved the members of each group to seperate hard disks. Anyway, I am wondering if anyone has advice on this problem.

Sincerely,
