Example

You have purchased 25 floating licenses and wish to set up a redundant server configuration on three Windows® computers. You request permanent keys for the redundant servers using License Key Center. You install the IBM Rational® License Server software on each of the three redundant servers; servers A, B, and C. When you receive the license file of 25 permanent floating keys, you install the license file on each server.

The three servers work as a team to manage all 25 floating licenses in unison. When you have 20 license keys checked out to your users and server A crashes, servers B and C continue to manage the 25 licenses.
Important: It is a common misconception that separating redundant servers across multiple sites (for example, one in the U.S., one in Europe, and one in Asia) provides maximum fault tolerance. This is not the case. Redundant servers should always be at the same site and on the same subnet.
To configure redundant license servers:
  1. Install Rational License Server software on three computers. See Working with a supported network configuration and Installing the server software on a Windows server.
    Attention: Use a redundant environment of either all Windows servers or all UNIX® system servers.
  2. Import a license file that you receive from IBM on each license server. See Using floating keys on a Windows license server for more information.
  3. Start the license servers. The sequence is not important, but you should start the servers soon after one another. See Starting the Windows license server for instructions.
  4. Give client users the Primary, Secondary, and Tertiary (Backup) license server host names in the order in which you requested them in License Key Center. They must enter the host names in their License Key Administrators (LKAD).
