Kernel Parameter Requirements - HP-UX Installation
To install and run the common components on HP-UX, the following kernel parameter
requirements must be met or exceeded:
■
The msgmax and msgmnb upper limits must be set to the following values to
ensure that the common components function properly:
msgmax = 32768
msgmnb = 65535
After the upper limits are set and the parameters are updated during the
installation, issue the following command to check whether a restart is required:
$ /usr/sbin/kmtune -u
Restart your computer for the changes to take effect if you encounter a message
similar to the following statements:
WARNING: maxfiles cannot be set dynamically.
WARNING: maxusers cannot be set dynamically.

Many kernel parameter values must be set at required minimum levels. If you
change a kernel parameter, you must rebuild the kernel.
To update the kernel parameter values and rebuild the kernel
1. Enter sam at the command prompt.
The sam utility starts running.
2. Click kernel configuration, configurable parameters.
