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.
