Alias names (or just "aliases") are intended to provide a more user-friendly means of
referring to ASM files, rather than using the system-generated filenames. You can create

simplified recovery through RESETLOGS feature is an enhancement to recovery
operations so that previous incarnation backups can be used for recovery of the current
database incarnation. You use this feature when you have performed an incomplete
