PM07487: INCORRECT SPANNED RECORD SEGMENTATION, BLOCK 7, RECORD 6

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• After unload a PDS (RECFM=VB, LRECL=32756, BLKSZ=32760)
  to a sequential spanned dataset
   (RECFM=VS, LRECL=32760, BLKSZ=32760).
  Trying to view this sequential dataset using the File Manager
  shows up  message:
  Incorrect spanned record segmentation, block 7, record 6
  
  block 6 starts with:
  7FF80000  7FF40100  00000000
  block 7 starts with:
  00160000  00120200  40404040
  
  So block 6 carries a 1st segment, block 7 a last segment.
  This looks valid as described in DFSMS Using Data Sets manual.

  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  ****************************************************************
  File Manager's reading of spanned data sets assumes the logical
  record length will not exceed the defined lrecl of the data set,
  with the exception of LRECL=X data sets.
  This assumption proves to be invalid in the user case of a data
  set created by IEBCOPY.
  

Problem conclusion

• File Manager has been updated in order not to check if the
  logical record length (being reassembled from segments) is
  exceeding the lrecl of the data set.
  File Manager will not use DFSORT when processing large spanned
  records.
