You should :

1.Multiplex the control file
2.Include the full pathname in CONTROL_FILES
3.Backup the control file after the database structure changes


Control files:
1.Are sized by CREATE DATABASE keywords
2.Hava a reusable section that can be expand due to Recovery Manager update.


Purpose of Multiplexing:
storing each copy of control files on a different physical disk.

Keywords in the CREATE DATABASE or CREATE CONTROLFILE commands :
1.MAXLOGFILES
2.MAXLOGMEMBERS
3.MAXLOGHISTORY
4.MAXDATAFILES
5.MAXINSTANCES

A new control file must be created to change the size of the space created by these keywords.
