Archivelogs in FRA

DB: 11.2.0.3

OS: Red Hat Linux 6.8

Issue:  FRA in my test box keeps filling up with archivelogs.  I would like to keep archivelogs for 1 day, but I don't want to do any backups due to lack of disk space. Please advice how to make that change.

Any help and advice would be appreciated.

Thanks.
