<str> is a WORM storage area  and  cannot  be  a  uniform-format
  area.

  Explanation:  The WORM flag is set indicating  that  this  is  a
  WORM  storage  area  but the MIXED_FMT_FLG flag is not set; this
  setting contradicts the previous flag, because WORM  areas  must
  be mixed-format.  Verification of the FILID continues.

  User Action:  Correct the error with the RMU Restore command  or
  the SQL IMPORT statement and verify the database again.
