RMAN useful information
The RMAN commands "crosscheck archivelog all" and "delete noprompt expired archivelog all" are used to clear RMAN's lookups so that the next RMAN run of "backup archivelog" does not look for non-existent archivelogs. However, you select "v$archived_log" and it will still see all the archive logs.
The number of records in V$ARCHIVED_LOG is 467, the records_used, last_index & last_recid in V$CONTROLFILE_RECORD_SECTION are 467, the number seems to be the same as in V$ARCHIVED_LOG.
V$ARCHIVED_LOG entries will be maintained for as long as CONTROLFILE_RECORD_KEEP_TIME.
V$CONTROLFILE_RECORD_SECTION shows you the number and size of the entries.
