2.4 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, as described in the following sections.

•“Perl prerequisites”

•“Kernel parameters” (page 13)

•“TIME_WAIT setting” (page 14)

•“Large file support” (page 14)

2.4.1Perl prerequisites

The HP-UX Directory Server uses the Perl version installed with the operating system in /opt/ perl_64/bin/perl. If this Perl version is not installed, contact HP support.

2.4.2 Kernel parameters

HP Recommends that you set the following kernel parameters with the system default values:

Kernel Parameter

System Default Value

max_thread_proc

256

maxfiles

2048

maxfiles_lim

4096

nproc

4200

Kernel Parameter

Recommended Value

maxdsiz_64bit

If you use the default values for the above parameters,

 

set the value for this parameter to at least 512 MB. This

 

assumes that the Directory Server processes are tuned to

 

use a single heap arena.

 

If you configure a large entry cache for your Directory

 

Server, you will require more heap space, which means

 

assigning a higher value to maxdsiz_64bit. Instead of

 

attempting to predict how high the value should be (this

 

is difficult to do), HP recommends setting it high initially

 

and then tuning it to a lower size if desired.

To determine the current values of these kernel parameters, use sysdef(1M) or the following commands on an HP 9000 or an HP Integrity (IA64) system:

#kctune grep -e max_thread_proc -e maxfiles -e maxfiles_lim -e nproc

After reconfiguration, you can expect the output of that command to match the values in the table above.

UX Direry Server specifications

HP UX Directory Server is a robust and scalable solution designed for managing directory information within enterprise networks. Developed by Hewlett-Packard (HP), this server offers an extensive set of features tailored to meet the needs of organizations that require an efficient way to store, manage, and retrieve identity and access data.

One of the key features of HP UX Directory Server is its ability to handle large directories with significant volumes of data. Built on a highly optimized architecture, it provides excellent performance and can support millions of entries without sacrificing speed or reliability. This capability makes it an ideal choice for large-scale deployments in enterprises that require high availability and responsiveness.

In addition to its scalability, HP UX Directory Server supports a wide range of protocols, including LDAP (Lightweight Directory Access Protocol), which ensures seamless integration with diverse applications and systems across various platforms. The server maintains standards compliance, which facilitates interoperability and simplifies administration tasks.

Security is a top priority for HP UX Directory Server, offering an array of features to protect sensitive information. It supports secure data transmission via TLS/SSL protocols, ensuring encrypted communication between clients and servers. Advanced access controls allow administrators to define fine-grained permissions, helping to safeguard directory data against unauthorized access.

Another salient feature of HP UX Directory Server is its replication capabilities. The server can replicate directory data across multiple instances, ensuring data consistency and availability in distributed environments. This feature is essential for businesses operating across different geographical locations or requiring failover solutions for disaster recovery.

HP UX Directory Server also comes equipped with tools for data management, including an intuitive administration console for configuring and monitoring the server. Additionally, it offers customizable schema capabilities, enabling organizations to tailor the directory structure to fit their specific needs.

Integration with existing identity management solutions is streamlined through connectors and APIs, allowing organizations to extend their directory services and enhance user experience.

In summary, HP UX Directory Server is a powerful directory management solution that combines scalability, security, and integration flexibility. Its support for industry standards, advanced replication, and comprehensive administrative tools makes it an essential asset for organizations seeking to manage identity and access efficiently. By leveraging this technology, businesses can improve their operational efficiency and ensure a secure and organized approach to directory management.
