Oracle (ASM) DB Backup with RMAN(1) 11/22/2018 3:06 AM 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; © Microsoft Corporation.
