Chapter 2. System Requirements

2.3.2. HP-UX System Configuration

Before setting up Directory Server, tune your HP-UX system so Directory Server can access the respective kernel parameters. To tune HP-UX systems, enable large file support, set the TIME_WAIT value, and modify kernel parameters.

•Section 2.3.2.1, “Perl Prerequisites”

•Table 2.6, “HP-UX 11i Kernel Parameters”

•Section 2.3.2.3, “TIME_WAIT Setting”

•Section 2.3.2.4, “Large File Support”

•Section 2.3.2.5, “DNS Requirements”

2.3.2.1. Perl Prerequisites

On HP-UX, Red Hat Directory Server uses the Perl version installed with the operating system in /opt/perl_64/bin/perl. Contact Hewlett-Packard support if this Perl version is not installed.

2.3.2.2. Kernel Parameters

The parameters to edit and the recommended values are listed in Table 2.6, “HP-UX 11i Kernel Parameters”.

2.3.2.3. TIME_WAIT Setting

Normally, client applications that shut down correctly cause the socket to linger in a TIME_WAIT state. Verify that the TIME_WAIT entry is set to a reasonable duration. For example:

ndd -set /dev/tcp tcp_time_wait_interval 60000
