Error description

• DBD/PSB/ACB Mapper causes ABENDS0C4 when it accesses a loaded
  DBD to generate a PSB report under certain condition.  The
  utility loads the DBD which is referred by the PSB several
  times.  The problem is caused when the loaded DBD addresses are
  different each time.

  This APAR fixes DBD/PSB/ACB Mapper not to cause ABENDS0C4 when
  it accesses a loaded DBD to generate PSB report.
  It is caused when the loaded DBD addresses are different each
  time.
  DBD/PSB/ACB Mapper calculates an address for internal use from
  the loaded DBD when it loads DBD first time. The utility uses it
  to the loaded DBD when the utility loads DBD again.
  If the loaded DBD addresses are different each time, the
  utility has a possibility to access unavailable address and it
  causes ABEND.
  
  DBD/PSB/ACB Mapper is fixed to calculate this address for each
  load.
  This APAR also fixes same problem for generating DBD report.
