ARC0: Error 19809 Creating archive log file to ‘+FRA’ errors

You have following choices to free up space from recovery area:
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 to reflect the new space.
4. Delete unnecessary files using RMAN DELETE command. If an operating system command was used to delete files, then use RMAN CROSSCHECK and DELETE EXPIRED commands.
