PI57211: DBD/PSB/ACB COMPARE CAUSES GETMAIN FAIL WHEN IT PROCESSES ACBLIBS WHICH INCLUDE MANY PSBS THAT REFER LOGICAL DBD

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• DBD/PSB/ACB Compare causes GETMAIN fail when it processes
  ACBLIBs which include many PSB type ACBs that refer logical
  DBDs.  If many PSB type ACBs that refer logical DBDs exist in
  ACBLIBs and the utility processes these members, the utility
  does not issue FREEMAIN after the process. As a result of this,
  the accumulated used area causes out of storage and GETMAIN fail
   occurs.

  ****************************************************************
  When the DBD/PSB/ACB Compare compares ACBLIBs with REPORT=SOURCE
  control statement, the utility uses the function of the
  DBD/PSB/ACB Reversal to decode the member.
  If the DBD/PSB/ACB Reversal processes PSB type ACB that refers
  logical DBDs, the utility missed to do FREEMAIN for these DBDs
  after the process.
  As a result of this, if the DBD/PSB/ACB Compare processes many
  PSB type ACBs that refer logical DBDs, the accumulated used
  area causes out of storage.
  
  This APAR fixes the DBD/PSB/ACB Reversal to do FREEMAIN for
  these DBDs after the process. Then the DBD/PSB/ACB Compare does
  not cause GETMAIN failure.
