NAME
     stune - file format

SYNOPSIS
     stune

DESCRIPTION
     The stune file contains local system settings for tunable parameters.
     The parameter settings in this file replace the default values speci-
     fied in the mtune file, if the new values are within the legal range
     for the parameter specified in mtune. The file contains one line for
     each parameter to be reset. Each line contains two whitespace-
     separated fields:

     1.   external name: This is the external name of the tunable parameter
          used in the mtune file.

     2.   value: This field contains the new value for the tunable parame-
          ter. In addition to an integer value, this field may also contain
          a formula using other parameter names. Formulas may have
          parentheses, multiplication, division, addition and subtraction.
          Example: (NPROC*10+5). White space is not allowed in a formula.

     The file stune normally resides in /etc/conf/cf.d. However, a user or
     an add-on package should never directly edit the mtune file. Instead
     the idtune command should be used.

     In order for the new values to become effective the Reliant UNIX ker-
     nel must be rebuilt and the system must then be rebooted.
