PK07881: ABENDS0C4 IN FABH0118 WHEN WRONG DBD USED. SEGMENT LENGTH MISMATCH BETWEEN ACTUAL SEGMENT AND THAT DEFINED IN DBD.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When the wrong DBD was used, a mismatch in segment length
  occurred between the actual segment and that defined in the DBD,
  leading to ABENDS0C4-11.

  * PROBLEM DESCRIPTION: HSSR Engine receives ABENDS0C4-11 in    *
  *                      the FABH0118 load module in             *

  ****************************************************************
  * RECOMMENDATION: Apply the maintenance for this APAR.         *
  ****************************************************************
  HSSR Engine receives ABENDS0C4-11 at FABH2008+X'4D2' in
  the FABH0118 load module, when a segment data to be retrieved
  is over the block boundary because of a mismatch in segment
  length between the actual segment and that defined in the DBD.
  

Problem conclusion

• The modules FABH200n (n=7,8,9) have been modified as to verify
  whether the segment data to be retrieved is stored within
  the block.
  
  If it is over the block boundary, a new message FABH0556E is
  issued and the processing is ended abnormally with the user
  abend code 4013.

  FABH0556E AN OCCURRENCE OF SEGMENT segmname IN DBD dddddddd
            OVER THE BLOCK BOUNDARY
  
  Explanation: HSSR Engine detects an incorrect occurrence of
  the segment segmname, which is stored over the block boundary.
  If it is a fixed-length segment, the segment length which is
  defined in the DBD dddddddd  can be inconsistent with
  the actual segment.
  
  System Action: HSSR Engine ends abnormally.
  Programmer Response: Check whether the specified DBD is
  same as one used for inserting the segment.
  Problem Determination:
  Register 6 contains the address of the segment data,
  register 5 contains the segment length which is defined in DBD,
  and register 7 contains the address of the block boundary.
