PK80666: VARIOUS DFR PROBLEMS FOUND INTERNALLY THAT NEED TO BE ADDRESSED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Here is a list of items being addressed:
  1. The incorrect FSE is set to the segment of SDEP when
     recovering with X'4026' log.
  2. IMS V6 APAR: PQ05913 changed the length of the work area that
     is passed to IMS user exit: DFSFLGX0.
     DFR is not yet enhanced for this apar.

  ****************************************************************
  The following problems are fixed by this APAR:
  1. The incorrect FSE is set to the segment of SDEP when
     recovering with X'4026' log.
  
     The DFR processes the IOT-EEQE log (X'4026') for the segment
     of SDEP.
     At the time, since DFR sets the access mode and issues the
     ICM instruction using the GPR15 for obtaining the FSE value
     after AR15 is used as work register for the GETMAIN macro by
     the system, the right value for FSE is not obtained.
  
  2. IMS V6 APAR: PQ05913 changed the length of the work area that
     is passed to IMS user exit: DFSFLGX0.
     DFR is not yet enhanced for this apar.
  
     APAR: PQ05913 increases the size of this work area from 256
     bytes to 512 bytes.
  

Problem conclusion

• The following modules and macros have been modified.
  (x = 8, 9 or A)
  *
  DFRARMOx  - When FUNC=SET is specified, the DFRARMOx macro
              issues a DFRARCLx macro for clearing all ARs, before
              setting the access mode.
  DFRCMRCx  - This module was changed so that all ARs to be used
              are specified to the DFRARMOx macro reflecting the
              change of the DFRARMOx macro.
  DFRNLG0x  - This module was changed so that the FSE value of the
              segment of SDEP is not changed when the X'4026 log
              is processed.
  DFRLFRCx  - This module was changed so that the DFRARCLx macro
              is not issued before issuing the DFRARMOx macro
              reflecting the change of the DFRARMOx macro.
  DFRNLGEx  - This module was changed so that the size of the work
              area for IMS user exit:DFSFLGX0 is increased from
              256 bytes to 512 bytes.
  *
  DFRLFCKx +- These modules were modified to be re-assembled to
  DFRLFTLx |  reflect the change.
  DFRL591x |
  DFRL593x |
  DFRL595x |
