Home -> Community -> Mailing Lists -> Oracle-L -> Re: Copy of redo
Yes, definately...You can not rely on hardware mirroring as far as logs are
concerned. Also make sure these are mirrored on different mount points with
2 different controllers....Even if it is on one controller and that
controller gives any problem your database will be crashed.
One more suggestion for logs, if your resources allow, move log files out of
RAID5 and put it on other drives which are not using RAID5...to improve your
sequential writing...

Hi.....
I'm running 3 databases : 1 using disks mirror and 2 using raid-5.
I just want your opinion on this : do I need to have the copy of redo log
files (2 redo for each redo group) or not (because it's redundant and
decreasing performance) ?
