PH24099: A SINGLE JSON FIELD THAT EXCEEDS THE PAGESIZE SETTING FOR A MAP WILL CAUSE A VALIDATION FAILURE

APAR status

• Closed as program error.

Error description

• The problem occurs when using IBM Transforation Extender (ITX)
  on any platform to validate JSON data containing a field
  larger than the map Work Space Page Size.
  
  Example JSON data:
  
  [
    {
      "one": "field one data",
      "two": "field two data",
      "three": "field three data",
      "four": "field four data",
      "five": "field five data ... (greater than 65k bytes>"
    }
  ]
  
  A default map setting of WorkSpace=File, PageSize=64 and
  PageCount=8 will mean that the validation map (using the JSON as
  metadata as well as input data) would end with a failure:
  
  <ExecutionSummary MapStatus="Error" mapreturn="8"
  ElapsedSec="0.0533" BurstRestartCount="0">
     <Message>One or more inputs was invalid</Message>
  
  The problem occurs because the byte count of a single field
  ('five' in this example) exceeds the PageSize value.
  
  Changing the PageSize=64 setting to PageSize=128 (or larger
  than the field size) may be used as a workaround to resolve the
  problem.
  

Local fix

• ITXCQ - ITX00060316
  PB / PB
  Circumvention: The PageSize can be increased to cover any
  anticipated maximum byte count for a single field.
  

Problem summary

• Users Affected:
  IBM Transformation Extender customers using native JSON parse
  where field size exceeds page size
  
  Problem Description:
  A single JSON field that exceeds the PageSize setting for a map
  will cause a validation failure.
  
  Platforms Affected:
  All
  

Problem conclusion

• Fix buffer refill logic when input data element data size
  exceeds default data buffer size and data spans 2 pages.
