PFRATH

   PFRATH specifies the page fault rate above which the limit of
   a working set is automatically increased. The unit of measure
   is the number of faults per 10 seconds of processor time. At a
   setting of 120, for example, the system automatically increases
   the limit of a working set if it is faulting more than 120 pages
   per 10 seconds. Decreasing the value of this parameter tends to
   increase the limits of the working sets, while increasing its
   value tends to decrease their limits.

   On Alpha and Integrity servers, the default value is 8 page
   faults every 10 seconds.

   PFRATH has the DYNAMIC and MAJOR attributes. On Alpha and
   Integrity servers, PFRATH also is an AUTOGEN-altered parameter.
