Rman complete Recovery of datafile 12.1.0.2.0

Scenario Preview:

  •  The database is running in ARCHIVELOG mode
  • One or some non system datafiles  of a user tablespace are lost
  • Recovery Catalog is not being used
Solution :
  • Database will remain in open sate as non-system datafile is corrupted
  • Connect Rman on target database 
  • Validate database
  • Check restore database preview
  • Offline tablespace users
  • RESTORE TABLESPACE users( NOTE: FRA is default so it will automatically restore datafile from recent backup)
  • RECOVER TABLESPACE users
  • Make TABLESPACE users ONLINE
  • validate database
(Example b) - Restoration of datafile while taking backup from particular location.
