After installing LoadLeveler, you need to customize it by modifying both the administration file and the configuration file. The administration file optionally lists and defines the machines in the LoadLeveler cluster and the characteristics of classes, users, and groups. The configuration file contains many parameters that you can set or modify that will control how LoadLeveler operates.
In order to easily manage LoadLeveler, you should have only one administration file and one global configuration file, centrally located on a machine in the LoadLeveler cluster. Every other machine in the cluster must be able to read the administration and configuration file that are located on the central machine. LoadLeveler does not prevent you from having multiple copies of administration files but you need to be sure to update all the copies whenever you make a change to one. Having only one administration file prevents any confusion.
You can, however, have multiple local configuration files that specify information specific to individual machines. For more information on the global and local configuration files, refer to Configuring LoadLeveler.
Before working with these two files, you should read the following planning considerations to help you decide how to modify the files.
