  • Not everything. Check V$CONTROLFILE_RECORD_SECTION view. There are much more different records. – Mindaugas Riauba Mar 3 '15 at 19:10

  • This doc lists what must be in controlfile but not all the possible info. The simpliest example is information about backups and copies which is stored only in controlfile if you do not use RMAN catalog database. – Mindaugas Riauba Mar 3 '15 at 19:30
