PH61933: PERFORM BASIC COMPLIANCE CHECKING OF DATASET USED AS AN INPUT IMAGE COPY FOR THE UNLOAD

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Db2 HPU assumes that the datasets used as input image copies
  (either provided by the user or automatically determined by
  searching the DB2 catalog) needed for the COPYDDN option are
  valid. If this requirement is not fulfilled, Db2 HPU can unload
  incorrect data without any notification to the user.
  
  For example, the unload produces zero rows and completes with a
  normal completion code if all the following conditions are
  fulfilled:
  - the image copy must be sorted
  - the record size of the image copy is lower than the page size
  of the target tablespace
  
  - the first record of the image copy is not recognized as an
  header page of an image copy : i.e. the value of the character
  at offset 11 is equal neither to X38' nor to  x18'
  
  Db2 HPU should do some basic checking of the content of the
  datasets used as input images copies to detect obviously
  incorrect datasets.
