PQ65838: ENHANCES HIGH PERFORMANCE LOAD TO VALIDATE SEGMENTS EDITED BY A SEGMENT/EDIT COMPRESSION EXIT ROUTINE WITH A PAD PARAMETER.

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• A fifth parameter of 'PAD' has been added to the
  COMPRTN keyword of the SEGM macro by PQ34603 and PQ34604.
  High Performance Load newly supports the PAD parameter.
  If the fixed length segment is compressed by a segment
  edit/compression exit routine and the PAD is defined,
  the High Performance Load adjust the maximum segment
  length to the pad value.

  (1) A fifth parameter of 'PAD' has been added to the COMPRTN
      keyword of the SEGM macro by PQ34603 of IMS/ESA V6 and
      PQ34604 of IMS V7.
      High Performance Load newly supports the PAD parameter.
      If the fixed length segment is compressed by a segment
      edit/compression exit routine and the PAD is defined, the
      High Performance Load adjust the maximum segment length to
      the pad value.
  (2) High Performance Load erroneously uses the value includes
      VSAM record 0 for calculation of NUMBER OF TOTAL BLOCKS
      and AVERAGE SIZE OF FREE SPACE ELEMENT in the DATA SET
      STATISTICS report.
  (3) High Performance Load incorrectly reports LENGTH OF MAX in
      the SEGMENT STATISTICS report, because it doesn't add the
      maximum number of bytes by which fixed length segments can
      increase during compression exit to the segment length.
  

Problem conclusion

Temporary fix

Comments

• HP Load utility has been modified as follows:
  - Modify HPSRCMP6, HPSRCMP7, HPSRCMP8, HPSRHDL6, HPSRHDL7,
    HPSRHDL8, HPSRHRP7, HPSRHRP8, HPSRHSL6, HPSRHSL7, HPSRHSL8,
    HPSRRLD7, HPSRRLD8, HPSRRPR6, HPSRRPR7 and HPSRRPR8
    to validate segments edited by a segment/edit compression
    exit routine with a PAD parameter, and to report correctly.
