Installation guide

• Set your system to a different locale. The Tru64 UNIX operating system
includes National Language Support (NLS) for multiple environments.
Chapter 4 describes how to customize your system for these purposes, and
also discusses how to customize:
• Internationalization features for programmers and users
• Your time zone
• The environment needed to establish a system that meets the
requirements of your site’s security policy
• The tools you use to maintain adequate performance for operating
system components and for user applications
• Allocating processing (CPU) resources with the Class Scheduler
• The power consumption of certain hardware subsystems
1.4 Configuring the Kernel
You may need to tune your system to enhance performance, add new
devices, or install new software. These changes may require you to modify
your system configuration file. If you modify the system configuration file,
thereby reconfiguring the kernel, you must compile and boot a new system
image for the changes to take effect. Chapter 5 includes the following
information:
• Descriptions of the configuration files and the tunable options in the
files
• Instructions for configuring, compiling, and booting a new kernel
• Instructions for configuring a STREAMS module or driver into your
system
• Instructions for administering loadable drivers
1.5 Administering Dynamic Device Recognition
Chapter 6 describes the components you use and the tasks you perform in
order to administer the Dynamic Device Recognition capabilities of your
operating system. Dynamic Device Recognition (DDR) is a framework for
describing the operating parameters and characteristics of SCSI devices to
the SCSI CAM I/O subsystem.
You use the ddr_config
(8) utility and the ddr.dbase(4) text database to
make changes to the subsystem whenever you change the devices in the
SCSI CAM I/O subsystem. You make these changes after the operating
system is installed and without needing to reboot the operating system.
