Oracle RMAN restores the full backup of another machine on a new machine

Restore full backup of another machine on a new machine

1. Remember the directory structure and DBID of the original machine.

2. Create the corresponding directory structure on the new machine and pay attention to the user permissions.
/U01/oracle/admin/dbname/pfile bdump udump dpdump cdump
/Oradata/dbname/rman_backup flash_recover_sea archivelog

3. Place the backup set file in the original Backup Directory of the new machine.

3. Connect Rman to the default location.

5. Exit RMAN and re-import RMAN.
RMAN> shutdown
RMAN> EXIT
