[Oracle DataBase Server 12.1 Installation on Oracle Linux 6.7]: Final Backup (Hot Backup)

$ mkdir -p /u02/oracle/oradata/12.1/${ORACLE_SID}/scripts

$ cd /u02/oracle/oradata/12.1/${ORACLE_SID}/scripts

$ vi rmanscript.rman

RUN {
CONFIGURE DEVICE TYPE DISK BACKUP TYPE TO COMPRESSED BACKUPSET;
BACKUP FULL DATABASE TAG "FULL_DATABASE" PLUS ARCHIVELOG TAG "FULL_DATABASE_ARCHIVELOGS";
BACKUP CURRENT CONTROLFILE TAG "FULL_DATABASE_CONTROLFILE";
BACKUP SPFILE TAG "FULL_DATABASE_SPFILE";
}

Check the syntax of the created script file

$ rman CHECKSYNTAX @rmanscript.rman

Run the backup script

$ rman target / @rmanscript.rman

View the list of backups

RMAN> rman target /

RMAN> list backup of database summary;

With the following command, I specify that all backups except the last one should be marked as obsolete.

RMAN> CONFIGURE RETENTION POLICY TO REDUNDANCY 1;

Now I ask RMAN to delete obsolete backups (without confirmation).

RMAN> delete noprompt obsolete;

RMAN> list backup of database summary;

RMAN>  quit
