Hi,
format '/oradbs/disk_bakup/amx53s/amx53s_offline_$date'Can you modify output file format to amx53s_offline_%p_%s_$date to add piece number set number to make the outpfile name unique? Because here RMAN is creating a backup set with the name you are providing, and then for next backup set, it uses same name and thats why returns you error message of "file already exists". If you second backup set is created on next minute, file name will be different, but if in the same minute, file name will be same and this error will come.
