  * PROBLEM DESCRIPTION: The number of records to be sorted for  *
  *                      an unload  from an image copy (COPYDDN  *
  *                      option) with an ORDER clause is         *
  *                      overestimated which causes a useless    *

  *                      ressources and may lead the sort and    *
  *                      subsequently the unload to fail.        *
  *                      This can occur if the following         *

  *                      - the number of partitions of the       *
  *                       target table space is much lower than  *
  *                       the maximum number of partitions       *
