Does anyone use, or see any problems with, mirroring database files to provide a quick way to recover in case of a disk problem? We aren't yet using RAC, we do have a standby database set up at our disaster recovery site and we do weekly cold backups of the database. We're thinking that mirroring the database storage disks would be another layer of protection. Any comments? - Maureen -- //www.freelists.org/webpage/oracle-l
