PI04824: MSGDFR3503E WRITE ERROR RECEIVED RUNNING DEDB FAST RECOVERY

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The following error message was received running a DFR job:
  DFR3503E (024) AREA=areaname DD=ddname, WRITE ERROR,
    CI-NO=nnnnnnnn - ADS STOPPED
  
  The error occured when DFR set the dummy default segments for
  the pre-allocation CI's.  When interpreting the last CI, there
  was a logic error in the code.  This error caused DFR
  to incorrectly set the dummy default segment to the CI
  that is out of the AREA. An I/O error occurs while writing
  the CI and DFR issued the error message and canceled the
  recovery of the AREA.
  
  This is for IMS V13. For IMS V11 and V12 see APAR PI06810.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All IMS DEDB FAST RECOVERY Version 2         *
  *                 Release 2 (FMID=H1J2220) users who use the   *
  *                 DEDB SDEP segment in IMS V13.                *
  ****************************************************************
  * PROBLEM DESCRIPTION: If new pre-allocation CI of SDEP wraps  *
  *                      an area end before IMS failure, DFR     *
  *                      issues a MSGDFR3503E message by an I/O  *
  *                      error of the CI and cancels the         *
  *                      recovery of the AREA.                   *
  ****************************************************************
  * RECOMMENDATION: Apply the maintenance for this APAR.         *
  ****************************************************************
  When DFR sets the dummy default segments for the pre-allocation
  CIs, DFR uses a HI-A-RBA instead of a start RBA of the last CI,
  in order to interpret the last CI.
  Therefore DFR incorrectly sets the dummy default segment to the
  CI that is out of the area.
  

Problem conclusion

• The following module has been modified.
  *
  DFRL595D - This module was changed so that it may wrap an area
             end when an start RBA of a next CI is the same as a
             value of a DMACBRBA field.
