Ah, the chicken or the egg...

Control files are identified by the parameter (spfile/init.ora) file. If you
kept the parameters in the control file, how would the database know which
control files to read? And if a control file was lost? How would you edit the
control file to change the parameter to point to a different control file?

Sounds like a catch-42.
