The tunable manpages described in this manual are available on HP-UX 11i Version 1.6 systems with the man command as well as on docs.hp.com and on Instant Information and through the kcweb(1M) interface.

The manpages for tunable kernel parameters have a layout that is different from other manpages. The special headings and subheadings are described below.

NAME

This section contains the name or names of the tunable and a short description. Some manpages describe more than one tunable. The names are the names of the tunables as they appear in a kcweb(1M) or kmtune(1M) display.

VALUES

This section contains subsections that describe the values that can be applied.

Default Value

The value that is set on most systems when they are shipped. For most tunables, there should be no need to change the value from the default.

Allowed Values

The range of values that can be used for the tunable. Using a value that is outside the range specified can produce unexpected results.

Fail-safe Value

The value that is recommended for use when using the system in maintenance mode. Set this value when you are trying to recover from errors that have been caused by erroneous tuning of the system. If you set the tunable to this value, the system will boot at least in single-user mode without trouble caused by tunables set to improper values.

Recommended Values

Recommended settings for the tunable.

DESCRIPTION

This section describes what the tunable does and the information that you need to set the value of the tunable in a manner that is customized to the environment.

Under this section several questions that are relevant to the tunable are answered. The questions include:

  • Who Is Expected to Change This Tunable?

  • Restrictions on Changing

  • When Should the Value of This Tunable Be Raised?

  • What are the Side Effects of Raising the Value?

  • When Should the Value of This Tunable Be Lowered?

  • What are the Side Effects of Lowering the Value?
