Triad license managers use three computers for extra stability. If the computer managing the license file is not available, one of the other two computers takes over.
Requirements for using triad license managers:
- Install triad license managers only on stable computers not scheduled for frequent shutdowns.
- The three license manager computers should be on the same subnet. Never configure triad license managers with slow communications or dial-up links.
- The system administrator should detect when a license manager computer goes down and should restart it as soon as possible.
If only two license manager computers are running, the situation is worse than a single license manager computer, because there are two points of failure.
