Anwender von z/OS V2R2 dürfen sich über die Anhebung des GDG Limits (GDGLIMIT, GDG extended Format) freuen: Statt 255, wie in bisherigen z/OS-Versionen, ist nun die Grenze auf 999 angehoben worden.

Das neue, höhere z/OS GDG-Limit färbt auf DB2 TEMPLATE’s ab:

 GDGLIMIT (integer)

    Specifies the number of entries that are to be created
    in a GDG base if a GDG DSN is specified and the base
    does not already exist.  If a GDG base does not already
    exist and you do not want to define one, specify a
    GDGLIMIT of zero (0).

  | The default value is 99.  The minimum value is 0.
  | The maximum value depends on the z/OS release on which
  | the subsystem is being executed.  Prior to z/OS V2R2, the
  | maximum value is 255.  Beginning with z/OS V2R2, the
  | maximum value is 999.  To use values greater than 255,
  | "GDGEXTENDED(YES)" must be specified in
  | SYS1.PARMLIB(IGGCATxx).  Otherwise, values above 255 will
  | fail during allocation.
