  * PROBLEM DESCRIPTION: User application using HP Unload API    *
  *                      gets into long-wait when HSSR calls     *
  *                      are issued to HALDB.                    *
  ****************************************************************
  * RECOMMENDATION: Apply the maintenance for this APAR.         *
  ****************************************************************
  User application using HP Unload API gets into long-wait,
  when the HSSR GU calls are issued to HALDB.
  Internally, BSAM CHECK macros are issued twice erroneously
  without an intervening READ macro at changing the target
  partition.
  

Problem conclusion

• The internal cause is that the BSAM CHECK macro is issued
  but an IO pointer (HDMCIO) is not cleared correctly for an
  overlapped I/O when the following request is for another
  partition's blocks. For the IO pointer, the CHECK macro is
  issued again.
  
  The modules FABHA02 and FABHA03 are modified as to clear the IO
  pointer correctly.
