How to increase the maximum number of control files? ORA-00208 number of control file names exceeds limit of num
  
  Cause:    An attempt was made to use more control files than Oracle
  supports. The limit is given in the message.
  
  num = 8.


I need to create 11 control files.
It is clearly documented that the parameter can not have more than 8 values.

CONTROL_FILES


  Range of values:  1 to 8 filenames
