PH23019: MACRO <HLQ>.SCSQMACS ( CSQDQWHS ) MAPS SMF 115 RECORD LAYOUT INCORRECTLY

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Macro CSQDQWHS maps the product section of the SMF 115 record
  incorrectly due to an error in its assembler portion. This
  causes fields within the record to not align properly within
  the data structure. This is caused by a Define Storage
  Statement of x7B length at offset x21 (defined as 'Unused')
  

Local fix

• The above DS can be removed, which will align fields (QWHSTIME
  and QWHSDURN) as expected

  * PROBLEM DESCRIPTION: The assembly version of the MQ standard *
  *                      header (QWHS) maps the SMF 115 record   *
  *                      layout incorrectly.                     *
  ****************************************************************
  Assembly macro CSQDQWHS maps field QWHSFLAG1 within the product
  section of the SMF 115 record incorrectly, declaring 8 bytes for
  the field instead of 1. This error shifts the offset of all
  subsequent fields within the macro 7 bytes higher than they
  should be.
  

Problem conclusion

• Assembly macro CSQDQWHS has been updated to correctly define
  field QWHSFLAG1 as 1 byte, containing bit flag QWHSSMFC.
