HP-UX System Administrator's Guide: Routine Management Tasks

NOTE: Tunable kernel parameters can be static or dynamic (not requiring a system
reboot or kernel rebuild). The list of dynamic tunables is continually growing. To
determine which tunables are dynamic on your system, use the kmtune command (see
the kmtune(1M) manpage), or see the Kernel Configuration portion of HP SMH. In
HP SMH’s Tunables screen. You can tell at a glance whether or not the value of a
particular tunable can be changed without a reboot.
Use the kctune command or the kcweb web interface. See kctune(1M) and kcweb(1M).
Configuring Kernel Tunable Parameters Using HP SMH
1. Access the HP System Management Homepage (HP SMH) as root.
2. Select Tools, Kernel Configuration, Tunables. This will display the Kernel
Configuration page with the Tunables tab displayed.
3. Click on the Modify Tunable action on the right side of the page. This will display
the Modify Tunable page.
4. You can now reset the tunable default, enter a new value, or log comments.
5. Click on Modify to complete the change.
For more information on dynamic tunables, see HP-UX System Administrator’s Guide:
Configuration Management and the Dynamically Tunable Kernel Parameters in HP-UX 11i
whitepaper at http://docs.hp.com.
CAUTION: Make sure you read the help for all the parameters related to any parameter
you are considering changing. In the case of maxuprc, you would need to read the
help on nproc as well as maxuprc.
