Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When Advanced ACBGEN is run for IMS V12 or later to acbgen index
  DBD, DFS0909I DBD IS NOT A VALID DBD is issued and the index
  DBD is not built.
  The SYSIN control statement is specified as the following:
    BUILD DBD=(primary DBD),BLDPSB=NO
    BUILD DBD=(index DBD),BLDPSB=NO

  This APAR fixes Advanced ACBGEN not to fail to generate index
  DBD with DFS0909I DBD IS NOT A VALID DBD issued incorrectly when
  running for IMS V13 or IMS V12 after APAR PM60450 is applied.
  
  When the utility runs with BUILD DBD=(primary DBD, index DBD),
  BLDPSB=NO in SYSIN control statement to acbgen of Full Function
  database, the problem occurs.
  
  The problem is caused by the following reason.
   IMS V12 APAR PM60450 changed IMS module DFSDLB00 that Advanced
   ACBGEN depends to work with and IMS V13 includes this change
   in base code. The module was changed to add an additional LOAD
   request of primary DBD when processing index DBD.
  
   Advanced ACBGEN has a special LOAD process to save the once
   loaded DBD in the storage and re-use it instead of LOAD
   process. The re-used one is placed at a fixed address, unlike
   in the case of LOAD process which uses dynamically
   obtained address. For Full Function database, index DBD and
   primary DBD are loaded in several times and each of them is
   placed at the fixed address.
  
   When the additional LOAD request of primary DBD is issued,
   Advanced ACBGEN overwrites loaded index DBD placed at the
   fixed address used in later with primary DBD. It causes
   inconsistency of the index DBD processing and issues DFS0909I
   and stops to acbgen the index DBD.
  
  Advanced ACBGEN is fixed to support the additional LOAD request
  during processing of index DBD.
