PH15721: DBD/PSB/ACB REVERSAL, COMPARE, MAPPER DOES NOT PROCESS PSB WHICH HAS OVER 64K SENSEG OFFSET CORRECTLY

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• IMS V14 PSBGEN and ACBGEN have been fixed with IMS APAR
  PI69628/UI44983 to generate PSB and PSB type ACB correctly when
  PSB and PSB type ACB meet the condition described in PI69628.
  DBD/PSB/ACB Reversal, Compare and Mapper utilities cannot
  process such PSBs or PSB type ACBs generated by IMS V14 with
  PI69628 or later version. The utilities report PSB is not a
  valid PSB without processing PSB or report ACB without INDICES=
  parameter.

  ****************************************************************
  IMS PSBGEN and ACBGEN have been fixed with IMS APAR PI69628.
  
  IMS APAR fixes the ACBGEN problem which originates PSBGEN
  problem. When IMS PSBGEN with PI69628 generates PSB which is
  very large (numerous DB PCBs) and has INDICES parameter coded on
  SENSEG statement and has over 64K SENSEG offset, it builds
  extended operand table to save new SENSEG offset.
  
  Several LIU utilities need to use extended operand table for
  these PSB or PSB type ACB to get the value of INDICES parameter.
  
  This APAR fixes the following LIU utilities to process PSB and
  PSB type ACB using extended operand table and new SENSEG offset
  when PSB has over 64K SENSEG offset.
  
  - DBD/PSB/ACB Reversal
  - DBD/PSB/ACB Compare
  - DBD/PSB/ACB Mapper
  - Consistency Checker
  - Catalog Manager
  - PSB Map Viewer
  
  Without applying this APAR, these utilities report that PSB
  is not a valid PSB and stop processing PSB. Also these
  utilities report that PSB type ACB is decoded or compared
  without specific INDICES= parameter which value is stored in
  extended operand table without applying this APAR.
