Seems you do not have archiving enabled.
The datbase should be in archivelog mode to peform the Hot backup.

follow the below mentioned steps:-
alter system set log_archive_start=true scope=spfile (To enable automatic archiving)
shutdown immediate
startup mount
alter database archivelog
alter database open
Archive log list (you can check through this view if it is enabled or not)
