NAME

       shlib_debug_enable - dynamically enable or disable online shared library debugging support

VALUES

   Fail Safe
   Default
       semantics is disabled

   Allowed values
DESCRIPTION

       This  tunable  dynamically  enables  (1) or disables (0) the online shared library debugging feature.  When this tunable is enabled, shared
       libraries of a running (active) application can be debugged.

   Who Is Expected to Change This Tunable?
       System administrators and developers who want to change the default behavior of

   Restrictions on Changing
       Changes to this tunable take effect immediately.  There is no need to reboot the system.

   When Should the Tunable Be Turned On?
       When there is a need to debug a shared library of a running (active) application, this tunable can be turned on.

       When this feature/tunable is not enabled, debugging of shared libraries can be done at application start time  through  the  command.   See
       chatr(1).

   What Are the Side Effects of Turning the Tunable On?
       If  an application which is being debugged for shared libraries is not MPAS (Mostly Private Address Space) executable, then the application
       will be converted to an MPAS executable type.  After the conversion, all rules which apply to regular MPAS executable type  does  apply	to
       the converted application until the process exits.  The rules apply even after being detached from the debugger.

   When Should the Tunable Be Turned Off?
       Administrators and/or developers who will not need the online debugging feature of shared libraries.

   What Are the Side Effects of Turning the Tunable Off?
       When  this  tunable  is	disabled,  then online debugging of shared libraries will not be possible beyond the existing hardware break point
       facility.  With hardware break points, only a limited number of breakpoints can be set.

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

WARNINGS

       All HP-UX kernel tunable parameters are release specific.  This parameter 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 values.  For information about the effects of installation  on  tun-
       able  values,  consult  the documentation for the kernel software being installed.  For information about optional kernel software that was
       factory installed on your system, see at

NAME

       NSTRSCHED - number of STREAMS scheduler daemons to run

VALUES

   Failsafe
   Default
   Allowed values
   Recommended values
DESCRIPTION

       This  tunable  defines  the  number  of multiprocessor (MP) STREAMS scheduler daemons to run on systems containing more than one processor.
       Note that uniprocessor (UP) systems do not use an MP scheduler daemon, but both MP and UP systems always  have  one  UP	STREAMS  scheduler
       (supsched).

       If  the	tunable  value is set to zero, the system determines how many daemons to run, based on the number of processors in the system.	If
       the tunable value is set to a positive, non-zero value, that is the number of smpsched daemons that will be created on an MP system.

       Note: This tunable is for use by specific HP products only.  It may be removed in future HP-UX releases.

   Who Is Expected to Change This Tunable?
       Any customer.

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

   When Should the Value of This Tunable Be Raised?
       This tunable is for use by specific HP products only.  It may be removed in future HP-UX releases.

   What Are the Side Effects of Raising the Value of This Tunable?
       It could change the system performance unpredictably.

   When Should the Value of This Tunable Be Lowered?
       This tunable is for use by specific HP products only.  It may be removed in future HP-UX releases.

   What Are the Side Effects of Lowering the Value of This Tunable?
       It could change the system performance unpredictably.

   What Other Tunable Should Be Changed at the Same Time as This One?
       None.
