Noarchivelog Database Recovery Via Rman



  • Your database is running in No Archive log mode and you have daily/weekly RMAN backup configured.

  • One fine day, your server crashed and you lose one of the disks or all the disks.

  • You have no other option but to restore the whole database backup to point of last valid backup.
