kctune to change hpux tunable parameters from CLI

kctune is the administrative command for HP-UX kernel tunable parameters. It gives information about tunable parameters and their values, and makes changes to tunable values. This command can work with any saved kernel configuration, or with the currently running kernel configuration, depending on the use of the -c flag (see below). By default, changes to the currently running kernel configuration are applied immediately. Some changes cannot be applied without a reboot; if any such changes are requested, or the -h flag is given, all changes on the kctune command line will be held until next boot. Super-user permissions are required when making changes to tunable values. EXAMPLES To see all tunables and their current values: $ kctune To see which tunables have new values being held until next boot: $ kctune -D To see verbose information about a tunable: $ kctune -v tunablename To set a tunable value on the running system: $ kctune tunable=12 To set a tunable value to be used when the system reboots: $ kctune -h tunable=12 To increase a tunable's value by 100: $ kctune tunable+=100
