1. Consider changing rman retention policy. If you are using Data Guard,
Then consider changing rman archivelog deletion policy.
2. Back up files to tertiary device such as tape using RMAN
Backup recovery area command.
3. Add disk space and increase db_recovery_file_dest_size parameter
Reflect the new space.
