       realtime applications

VALUES
   Failsafe
   Default
   Allowed Values
       is allowed.

   Recommended Value
DESCRIPTION
       The tunable defines how many priority values to support for  POSIX  1.b
       realtime	 applications.	A larger value provides additional flexibility
       to applications in managing relative priorities	of  all	 threads  with
       respect to each other and with respect to other applications running in
       the system.  However, a larger value adds processing  overhead  in  the
       operating system in terms of managing larger run queues with the possi‐
       bility of increased search times.

   Who Is Expected to Change This Tunable?
       Anyone.

   Restrictions on Changing
       Changes to this tunable take effect at next reboot.

   When Should the Value of This Tunable Be Raised?
       When the system is primarily running POSIX realtime  applications,  and
       requires	 additional  flexibility  in  managing	relative priorities of
       applications.

   What Are the Side Effects of Raising the Value?
       Raising the value of the tunable may cause some operating system	 over‐
       head due to larger and possibly more sparse run queues.

   When Should the Value of This Tunable Be Lowered?
       The default value of the tunable is already set to the minimum possible
       value.

   What Other Tunable Values Should Be Changed at the Same Time?
       None.

WARNINGS
       All HP-UX kernel tunable parameters are release specific.  This parame‐
       ter  may	 be  removed or have its meaning changed in future releases of
       HP-UX.

       Installation of optional kernel software, from HP or other vendors, may
       cause  changes  to  tunable parameter values.  After installation, some
       tunable parameters may no longer be at the default or recommended  val‐
       ues.  For information about the effects of installation on tunable val‐
       ues, consult the documentation for the kernel software being installed.
       For  information	 about	optional  kernel  software  that  was  factory
       installed on your system, see at
