In my previous posts, I have shown the Logical Structure and the Physical Contents of the Controlfile. It is clear that some of the sections (e.g. for "ARCHIVED LOG" entries) have many slots (or "records") not all of which are currently in use.
What happens if you recreate the controlfile ? Since my first post, I have generated some more Backup Pieces and ArchiveLogs (and purged ArchiveLogs) so the RECORDS_UESD or INDEXes of "BACKUP DATAFILE", "BACKUP PIECE" and "ARCHIVED LOG" in this listing are different from that first listing.

The trace that is generated with the "alter database backup controlfile to trace ..." command actually contains the SQL statements that can be used to recreate the controlfile. There are a number of useful comments also added.
Essentially, there are two sets of SQL commands.
The first set, titled "Set #1" is for the NORESETLOGS scenario where all the Online Redo Log files are available.
The second set, titled "Set #2" is for a RESETLOGS scenario where Incomplete Recovery is required because not all the Online Redo Log files are available.
In my case, I have all my Online Redo Log files so I do not lose any data and I can use the commands from Set #1.

What do I now see in the Logical Entries in the Controlfile ?

Recreating the Controlfile resulted in loss of information on all ArchivedLogs and RMAN Backups !
Compare the RECORDS_USED and INDEXes for "ARCHIVED LOG" and "BACKUP %" entries against the listing obtained before recreated the Controlfile. (A few ArchivedLogs were generated by the "ALTER SYSTEM ARCHIVE LOG ALL" command in the script itself).
Can I add that information back ?

RMAN>
Yes ! RMAN can "add the information" back into the Controlfile using the CATALOG command (also see this earlier post on the CATALOG command)-- as long as you know where the Backups and ArchiveLogs ARE ! (Another good reason to use a single FRA location !)

The RECORDS_USED for ARCHIVED LOG" and "BACKUP DATAFILE" and "BACKUP PIECE" are now properly reset.
I would NOT advice that you periodically recreate your Controlfile.
But this is an available method to "reset" the controlfile. I could also take this opportunity to increase controlled-values like MAXLOGFILES, MAXMEMBERS and MAXDATAFILES (or even MAXINSTANCES !).

Note how I have increased the "DATAFILE" RECORDS_TOTAL for "DATAFILE" from 1024 to 2048 and for "REDO LOG" from 16 to 24 and "LOGHISTORY" from 292 to 584.
