14.Schema checking: on (default).

Note: leave it on because it specifies whether the database schema will be enforced during entry insertion or modification. When measuring performance data based on exact searches, this core server configuration attribute does not affect performance.

Performance Monitoring Tools

sar (system activity reporter)

The sar tool periodically samples and averages performance information from the kernel, especially useful for extracting CPU activity and compiling raw data on system performance. More information about sar is available on HP-UX in the sar(1M) manpage.

HP Caliper

HP Caliper is a general-purpose performance analysis tool for applications on Itanium®-based HP systems. HP Caliper allows you to understand the performance of your program and to identify ways to improve its run-time performance. HP Caliper works with any Itanium®-based binary system and does not require your applications to have any special preparation to enable performance measurement.

With the aid of HP Caliper, we can determine what the system is doing when running a benchmark test. More information about HP Caliper is available at: http://h21007.www2.hp.com/dspp/tech/tech_TechSoftwareDetailPage_IDX/1,1703,1174,00.html

Performance Data Creation

Test data generation

The data used for the performance testing is generated by dbgen.pl script, which is in the

/opt/dirsrv/bin directory of a system installed with HP-UX directory server product. This script generates inetorgPerson entries with highly random attribute values. The dbgen script is used to generate the data, and ldif2db is used to populate data to the directory server.

Search script generation

To perform search and other operations on the directory server, HP-UX DS provides the rsearch and ldclt scripts. These scripts are located in the /opt/dirsrv/bin directory. Both scripts are used for presentation of directory server performance results in this white paper.

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.
