Each system that is a license server needs to run both FlexNet and the Licensing Interconnect; this requirement applies to both single servers and triads. We recommend that you always configure triads to manage FlexNet and the Licensing Interconnect independently. Keep the following points in mind when working with triads.

In a triad environment, the Licensing Interconnect functions in an independent manner. All systems are active and can all accept client requests at any time, unlike FlexNet, where only one of the three is serving licenses at a time. Although we strongly recommend that each of the systems in the triad is running a Licensing Interconnect, unlike FlexNet, a quorum of Licensing Interconnects is not required.

We recommend that you include the path to each of the triad systems in the license path of each of the clients via the ansyslmd.ini file on the client machines. The license server listed first in the client license path is tried first to check out a license. If no licenses are available, the second license server is tried.

If you need to change the order of the systems in your triad (for example, making the secondary server the primary), you will also need to change the license paths on the client machines to be consistent.

We do not recommend caching the license file of the other two servers in the triad. Since the same file is used on all three systems, it is unnecessary.

When shutting down the Licensing Interconnect on triad systems, initiating shutdown on one system will not shut down the Licensing Interconnect on other systems in the triad; you must shut each of them down individually.
