The Technical System Configuration(TechSysConf) product adjusts
various configurable kernel settings, as well, as other system settings
with the intent of improving system performance. TechSysConf determines
the system RAM to choose a set of values for kernel and system tunables.
These tunables are compared against any values you may already have
set, and if the proposed value is greater that the current value
the proposed value is used. The modifications that TechSysConf implements
are advantageous to the vast majority of users.
Summary
of Change |
 |
The HP-UX 11i v2 release delivers a restructured TechSysConf
bundle. This bundle no longer includes the
TC-OpenSource tools. The TC-OpenSource tools are still available, via
the Internet Express Media, though are not installed as part of
TechSysConf.
The changes to the TC-SysSetup product, that remains within
the TechSysConf bundle, in the HP-UX 11i v2 release, are:
Alters kernel configurable parameters,
assigning values that are proven to increase performance in technical
environments.
Alters selected system configuration files to facilitate
easier NFS, AutoFS, and NIS+ configuration.
Impact |
 |
The structure of the TechSysConf bundle has change to exclude
the TC-OpenSource product. The TC-OpenSource product is removed
from the target system during an update from HP-UX 11i v1.6, and
removes approximately 140 MB of information from /opt. All of the TC-OpenSource tools can be installed from
the Internet Express Media.
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 |
