Oracle (ASM) DB Backup with BR*Tools(4)
ASM database data files can be back up only by RMAN!
backup_dev_type = rman_util | rman_disk | rman_stage
backup_dev_type = disk
disk_copy_cmd = rman_set | rman
backup_dev_type = tape | pipe
tape_copy_cmd = rman
Following parameters were adjusted in init<DBSID>.sap profile (adjust the entries):
asm_root_dir = ASM
backup_dev_type = disk
disk_copy_cmd = rman
rman_channels = 12
rman_filesperset = 5
_rem_sql_call = yes
_remote_exec = ssh
_remote_copy = scp
asm_ora_sid = +ASM

Oracle (ASM) DB Backup with RMAN(1)
RMAN is a oracle utility to backup, restore & recovery of database.
Connect to Target database(the database on which Backup to be performed) as sysdba.
$ sqlplus "/ as sysdba“
Check if the database has been configured with ARCHIVELOG
SQL> select log_mode from v$database;
If the database has been not been configured with ARCHIVELOG mode then Shutdown and Startup the database in mount state
SQL> shutdown immediate;
SQL> startup mount;
Configure database in ARCHIVELOG mode.
SQL> alter database archivelog;
Check ARCHIVELOG destination, and if required it can be changed
SQL> archive log list
SQL> alter system set log_archive_dest_1='location=/home/oracle/arch' scope=both;

10. Oracle (ASM) DB Backup with RMAN(2)
11/22/2018 3:06 AM
Oracle (ASM) DB Backup with RMAN(2)
Check flash/fast recovery area location
SQL> alter system set log_archive_dest_1='location=/home/oracle/arch' scope=both;
Connect to RMAN prompt with target database
$ rman target /
Configure RMAN with controlfile auto-backup feature that will be auto-backup controlfile in case of major changes done in database
RMAN> configure controlfile autobackup on;
To enable backup optimization run the following command. [By default backup optimization has been configured OFF.]
RMAN> configure backup optimization on;
Configure retention policy for backup
RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 10 DAYS;
Start database backup
RMAN> backup database;
