PI06810: MSGDFR3503E WRITE ERROR RECEIVED RUNNING DEDB FAST RECOVERY

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 occurred 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 a retro-fit of APAR PI04824 for a IMS V11 or V12
  environment.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All IMS DEDB FAST RECOVERY Version 2         *
  *                 Release 2 (FMID=H1J2220) users who use the   *
  *                 DEDB SDEP segment in IMS V11 or V12.         *
  ****************************************************************
  * 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 modules have been modified.
  (x = B or C)
  *
  DFRL595x - 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.
  *
  DFRNRDOx - This module was changed so that a value may be set
             into DBLKFSOF (OFFSET TO FIRST FSE) field.
  *
