The RMS license server is a program that coordinates the use of a licensed application by multiple users and computers. This program usually runs on a computer that is located on the same subnet as any computer that needs to run the application.
The license server reads the licenses from the license file or can have them added into its memory. Each license identifies the valid uses of a single application or feature. There may be multiple licenses in a single license file. You generally add license codes to the license file by using the lslic utility.
The Clients
The computers that run the application are called clients. When a licensed application is started on the client, it sends a request for a license across the network to the license server. The license server grants the request if possible and returns an authorization message back to the client.
Note: A license server program need not run on a file server system or any specific hardware server. Any computer that meets the requirements is acceptable. Realistically, a system running on Pentium Processor 3 (or higher), 550 MHz and having 128 MB RAM is a good choice for measuring stress data.
