IDTUNE(1M)           INTERACTIVE UNIX System           IDTUNE(1M)



          NAME
               idtune - attempts to set value of a tunable parameter

          SYNOPSIS
               /etc/conf/bin/idtune  [ -f | -m ]  name  value

          DESCRIPTION
               This script attempts to set the value of a tunable parame-
               ter.  The tunable parameter to be changed is indicated by
               name.  The desired value for the tunable parameter is value.

               If there is already a value for this parameter (in the stune
               file), the user will normally be asked to confirm the change
               with the following message:

                    Tunable Parameter name is currently set to old_value.
                    Is it OK to change it to value? (y/n)

               If the user answers y, the change will be made.  Otherwise,
               the tunable parameter will not be changed, and the following
               message will be displayed:

                    name left at old_value.

               However, if the -f (force) option is used, the change will
               always be made and no messages will ever be given.

               If the -m (minimum) option is used and there is an existing
               value which is greater than the desired value, no change
               will be made and no message will be given.

               If system tunable parameters are being modified as part of a
               device driver or application add-on package, it may not be
               desirable to prompt the user with the above question.  The
               add-on package Install script may chose to override the
               existing value using the -f or -m options.  However, care
               must be taken not to invalidate a tunable parameter modified
               earlier by the user or another add-on package.

               In order for the change in parameter to become effective,
               the UNIX system kernel must be rebuilt and the system
               rebooted.

          DIAGNOSTICS
               The exit status will ne non-zero if errors are encountered.
