There is an entry in the system reference manual for an alter system command called CONTROL_FILE_RECORD_KEEP_TIME "...specifies the minimum number of days before a reusable record in the control file can be reused."
The default is 7 days, which is entirely too short for many places.
Google about for opinions on how this should be set for different ways
of dealing with archived logs like
