HP-UX 11i June 2004 Release Notes

HP-UX 11i Version 1 Operating Environment Applications
HP-UX 11i v1 Minimal Technical Operating Environment (MTOE)
Chapter 6

Installing the TC-SysSetup product changes kernel parameters, which results in a
kernel build and system reboot. Since most of the kernel parameters are selected for the
ability to improve performance in typical EDA and MDA application environments, a
performance increase should be realized without further kernel tuning.
Specific non-kernel changes include the following:
• Configure the system as an NFS server in /etc/rc.config.d/nfsconf.
• Set NFS daemons to 30 and BIO daemons to 16 in /etc/rc.config.d/nfsconf.
(Both daemon values are changed only if they increase current settings.)
• Modify the search sequence and fallback activities in /etc/nsswitch.conf.
• Enable AutoFS and automount in /etc/rc.config.d/nfsconf.
• Set read and write block size to 32K in /etc/auto_master.
•Configure /etc/passwd and /etc/group to import NIS-served data.
Installation Requirements
There are no unique system requirements or dependencies. This bundle is intended to be
installed on HP workstations and technical servers.
Kernel Configurable Parameters
The following table lists the kernel parameters that are changed by installing the
TechSysConf bundle. Existing parameter values are tested and are not changed if the
new value would be less than the current value.
