ORA-15220: invalid file attribute specification

What triggered the Error:

The keyword UNPROTECTED, MIRROR, HIGH, FINE, or COARSE was specified in a MODIFY FILE clause. These file attributes are immutable once a file is created.

What should we do to fix it:

Specify a ZONE keyword; for example, HOT, COLD, MIRRORHOT, or MIRRORCOLD.
