Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of QCF3.1 panels that allocate         *
  *                 data sets, used to pass information          *
  *                 between client and server, on SMS volumes.   *
  *                 The prefix of the names for these data       *
  *                 sets is defined by the customer in           *
  *                 parameter USRHLQ in start up script IQC31.   *
  *                 The data sets can be allocated on a          *
  *                 specified volume , or SMS vols can be used.  *

  *                      message is received retrieving the      *

  *                      in the QCF server job:                  *

  *                      The problem is that the data sets are   *
  *                      passed between client and server - both *
  *                      components allocating and un-allocating *

  *                      UNLOAD data set is the last to be un-   *
  *                      allocated by client and the first       *
  *                      to be allocated by server - in some     *
  *                      cases the timing is not correct-and the *
  *                      data set is not released when the       *
  *                      server requests it.                     *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The programs have been changed to do the un-allocate
  and allocate of the data sets in the same order -
  there is enough time for the operating system to
  finish the release of the data sets before they
  are requested by the other QCF component.
