Recovery manager is the best tool in oracle to make the backup of database. For this, I created the script for a simple physical backup, naming datafiles, spfile, controlfile and archivelog backups.
Simple rman backup
bkprman.sh – created to call the script of bkp rman – call bkprman.sql
bkprman.sql – physical backup renaming all datafiles, controlfiles and spfile – called by rman
