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.
