NAME    [Toc]    [Back]

     stune - local settings for	system tunable parameters

DESCRIPTION    [Toc]    [Back]

     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.
