Managing Systems and Workgroups: A Guide for HP-UX System Administrators

Configuring a System
Reconfiguring the Kernel (HP-UX 11i Version 2)
Chapter 3340
Changes to saved kernel configurations can be made by using the -c
(configuration) option. Such changes are made to the saved configuration
immediately, but they won’t affect the running system until that saved
configuration is either loaded or booted. See “Managing Saved
Configurations with kconfig” on page 352 for more information.
When changing tunable values, kctune supports the -B and -K options to
specify backup behavior, and the -C option to specify a log file comment.
See “Recovering from Errors” on page 364 and “The Kernel
Configuration Log File” on page 362 for details.
Managing Kernel Tunable Parameters with kcweb
kcweb can be used to query and change the values of kernel tunable
parameters (“tunables”) in the currently running configuration. Using
kcweb, you can
• modify the value of a tunable
• view details about a tunable
• search for a tunable
• check the current and next boot value for a tunable
• print details about a tunable or print a list of all tunables
You can view the tunables pane by choosing the tunables menu item
from the navigation column in kcweb.
