kctune(1M) kctune(1M)

1 kctune was successful. However, there were changes requested to the currently running system

which cannot be applied until the system reboots. Therefore, all of the requested changes are being

held until next boot.

If -D was speciﬁed, this return value indicates that there are tunable changes being held for next

boot.

2 kctune was not successful.

WARNINGS

kctune always checks the validity of tunable values before applying them to the running system. When

tunable value changes are held for next boot, or made to a saved conﬁguration, some of the validity checks

are not performed until the changed conﬁguration is booted. If any tunable values are found to be invalid,

messages will be printed to the system console during the boot process, and the default values for any

affected tunables will be used instead.

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
