PM14428: IN RELOAD (FABCUR3) WHEN DURSDWRK IS SPECIFIED AS DUMMY, IT DOESNOT ISSUE ANY WARNING MESSAGES AND SDEP SEGMENTS ARE LOST

APAR status

• Closed as program error.

Error description

• If DURSDWRK is specified as DUMMY or NULLFILE,  FABCUR3 does not
  issue any warning messages but SDEP segments are lost.
  This is because FABCUR3 (Reload) only checks whether DURSDWRK is
  specified in the JCL or not.
  An adjustment needs to be made to check if DURSDWRK is specified
  as DUMMY or NULLFILE for the unloaded data set that is created
  by the DEDB Unload utility ( FABCUR1 ) with SDEP=LOGICAL option,
  and for SDEP Relocation processing, to cause FABCUR3 to abend.

  <------ Problem Summary --------------------------------------->
  Reload requires DURSDWRK DD for the unloaded data set that is
  created by the DEDB Unload utility ( FABCUR1 ) with SDEP=LOGICAL
  option and for SDEP Relocation processing.
  When DURSDWRK DD is specified as DUMMY or NULLFILE in these
  conditions, Reload does not check the DD and ends normally.
  However some or all SDEP segments are lost.
  DEDBPC (Pointer Checker) issues FABA0141W message against the
  reloaded area.
  FABA0141W - NO SDEP SEGMENTS FOUND
  This message indicates that the reloaded area has no SDEP
  segments, that is all SDEP segments are lost.
  Unload abends with U3791 and FABC3791E message, and indicates
  that a root segment has a incorrect PCF pointer.
  FABC3791E - INVALID PCF POINTER IN AREA
  - SOURCE SEG SEG-CD:        1
       RBA   : 00008008
  - TARGET SEG SEG-CD:        2
       RBA   : 0014B0D0
  

Problem conclusion

• The logical unloaded SDEP segments are saved into DURSDWRK DD
  data set before the reload process, and are reloaded from its
  data set by FABCUR3 (Reload).
  FABCUR3 only checks whether DURSDWRK DD data set is specified
  on the JCL or not.
  When DURSDWRK DD data set is specified as DUMMY, FABCUR3 does
  not issue any warning messages and some or all SDEP segment are
  lost.
  FABCUR3 (Reload) has been modified to abend with U3750 when
  DURSDWRK is specified as DUMMY or NULLFILE for reloading SDEP
  segments logically, and for SDEP relocation processing.
