HP-UX 11i Version 2 Release Notes (October 2003)

Workstation- and Server-Specific Information
Technical System Configuration
Chapter 3
55
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 changes, unrelated to the kernel, include:
• 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.
These values should only be changed if it increases the setting.
• 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 32Kb in /etc/auto_master.
•Configure /etc/passwd and /etc/group to import NIS-served data.
There are no unique system installation requirements or dependencies. This bundle is
intended to be installed on HP Workstations and Technical Servers.
IMPORTANT Users who anticipate running a thousand or more of concurrent processes under either
the TCOE or MTOE should consider decreasing the kernel parameter maxssiz64_bit to
256MB, or increasing swap allocation to prevent resource exhaustion issues.
Compatibility
Potential conflicts with other install-time parameter specifications, such as SISP
enables, have been identified and addressed in TechSysConf.
Performance
The use of TechSysConf results in an all-around performance improvement on systems
with mid-range or large memory capacity.
Documentation
There are no documentation changes.
Obsolescence
Not applicable.
