Getting started with administering Lifecycle Query Engine

As a Lifecycle Query Engine (LQE) administrator, you might be responsible for a wide range of activities, including planning, installation, configuration, and management of the LQE servers in your environment. If you are new to LQE, this information will help you understand how it works, and how to ensure optimal performance.

Planning a Lifecycle Query Engine implementation

When you are deciding whether to use Lifecycle Query Engine to index the data from across your lifecycle management tools, there are several details to consider. Because the volume of data to be indexed can be considerable, and several factors can impact performance, you must carefully review the system requirements, deployment topologies, and best practices to ensure that the system performs as expected. The following resources can help:

Installing Lifecycle Query Engine

Lifecycle Query Engine is a Jazz™ Reporting Service component that is available in the web installer for IBM Engineering Lifecycle Management.
Note: While the default installation and setup using the wizard leads you to install all of the applications on a single server, this topology is not necessarily the best choice. Carefully consider the options. You can install LQE on separate servers, and even deploy it across several nodes, each with their own external relational database..
For more information, see the Interactive installation guide.
