area <str>, page <num>
  the <num>% fullness value for this data page does not fall
  within the <num>-<num>% range found on the space management page

  Explanation:  The data page's percentage  fullness  of  a  mixed
  area   falls   outside  of  the  range  of  percentage  fullness
  represented by the data page's space management page code.

  User Action:  Correct the error with the RMU Restore command  or
  the   SQL  IMPORT  statement  and  verify  the  database  again.
  Alternatively, the RMU Repair command may be used with the  SPAM
  qualifier  to  correct  this  problem.  Please note that the RMU
  Repair command should not be used unless you have a backup  copy
  or  an  exported  copy  of the database.  Because the RMU Repair
  command does  not  write  its  transactions  to  an  after-image
  journal  file, a repaired database cannot be rolled forward in a
  recovery process.  Therefore, Oracle Corporation recommends that
  a  full  and  complete  database backup be performed immediately
  after using the RMU Repair command.
