NAME
     stune - local settings for system tunable parameters

DESCRIPTION
     The file /var/sysgen/stune contains local system settings for tunable
     parameters.  The parameter settings in this file replace the default
     values specified in /var/sysgen/mtune/*, if the new values are within the
     legal range for the specified parameter.  Blank lines and lines beginning
     with the # or * characters are considered comments and are ignored.  The
     file contains one line for each parameter to be reset.  The syntax for
     each line is:

     parameter name[,tag] = value [ll|LL]

     parameter name   The name of the tunable parameter.

     tag	      Optional field that if specified controls whether the
		      parameter is used in the current configuration.  Use of
		      this field can permit multiple configurations to be
		      present in a single stune file.  See mtune(4) and
		      system(4) for more details.

     value	      The new value for the tunable parameter.

     ll|LL	      This optional field specifies whether the parameter
		      should be interpreted as a 32 or 64 bit quantity.

     The file stune normally resides in /var/sysgen.  You can edit this file,
     as root, as you find necessary.  However, it is suggested that you use
     the system tuning tool, systune(1M), instead of making changes directly
     to the stune file.	 systune makes specified changes in the stune file for
     you.  You should never directly edit the default configuration files in
     the mtune directory.

FILES
     /var/sysgen/mtune/*   default system parameters
     /var/sysgen/stune	   local settings for system tunable parameters

SEE ALSO
     lboot(1M), systune(1M), mtune(4), system(4).
