  it processes DEDB and tries to obtain lacked information from
  PSBs which refers DEDB.
  
  - The utility causes ABEND0C4 after GETMAIN error occurs.
  
  - The utility uses a lot of storage when it processes
  FUNC=CHECK_GENTIME even if it processes one member.
  
  
  This APAR fixes the Catalog Manager utility to correct
  FREEMAIN failure not to cause storage shortage.
  The APAR also fixes the utility to stop processing when it
  gets GETMAIN error.
  This APAR provides improvement of storage usage to process
  IMS directory which has a lot of members.
