Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The maximum number of extents per OSAM data set has increased to
  120 in IMS V14 or later.
  Space Monitor (SPMN) displays the wrong number of available
  extents of OSAM data sets in SPMN reports.

  ****************************************************************
  In IMS V14 or later, the maximum number of extents per OSAM data
  set has increased to 120. But, Space Monitor incorrectly treats
  it same as the maximum number of extents of IMS V13.
  As the result, the wrong number of available extents of OSAM
  data sets is shown in Space Monitor reports.

   Examples
  
    The following examples show how to calculate the number of
    allocatable extents from the number of extents currently
    allocated. Allocatable extents means the space that can be
    allocated under the current status of allocation. In these
  | examples, IMS V14 and no rotational position sensing (RPS)
    device is assumed.
