I think that the floating license does not mean the executable binary is
floating around but rather the license key the application need will be
getting from some license server running on the network. This involves
some network communication. However, for the node-locked case, the application
only look into a file somewhere in your local machine to get the license
key(a scrambled alphanumeric sequence generated from your hostname, host IP,
and when the license expire).
The license server software running on our SGI machines is developed by HP
and maybe it is been used by several other platform. Last week I just
installed SGI's CaseVision/WorkShop and I went thru lots of trouble to get
the license server running. And to my surprise, I did not see any other
product using the license server(although there are more than 20 servers
running and it should cover half on the GSFC campus).
Although I use the license server, my licenses are still not the floating
license. I splited into two half so that one machine got 3 license and the
other got 1.
I believe that what sales meant was each machine has a node-locked license
and three floating licenses can be used by anyone from any machine.
If you have node-locked license, you can run on that node even the network
or license server die. As for floating license, you can use all the licenses
even one node is dead. However, if the license server is dead or the machine
running the license server is dead, or the connection to that machine is
dead, no on can run the application.
Hope this help.
