You have purchased 25 floating licenses and want to set up a redundant server configuration on three UNIX® system 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 server partners; servers A, B, and C. When you receive the license file of 25 permanent floating keys, you install the license file on each server.
It is a good practice to have a homogeneous redundant server setup is (that is, all servers installed on the same operating system); however, heterogeneous environments are supported. For example, you could have two license servers installed on Solaris and one installed on HP-UX.
