Which license key do I want, and how do I install it?

You have decided to use EnSight as your post processor, you have downloaded the latest version from our website, and now all you need to get your analysis going is acquiring and installing the correct license key.

The first thing you need to decide is: which kind of key do I want? A Node Locked key, or a Floating key? That depends entirely on how you want to organize your workflow.


A Node Locked Key

If you select this kind of key, you will be able to access EnSight only from the machine for which the key is made. So, if you only purchased one seat for yourself, as you are the only EnSight user; or if you want to be able to run EnSight from everywhere, even when you are not connected to the web or you are on the other side of the world with respect to your lab, this is the key for you.


A Floating Key

This key is meant for a lab kind of environment. In a floating key, you have a single machine that controls how many people are using EnSight at the same time (the license manager machine). When you launch EnSight from a machine in the same network as your license manager, EnSight will ask the license manager if at the moment there are still open seats. If the answer is "yes", then EnSight opens and the number of open seats is decreased by one. If the answer is "no", then EnSight will open in the Free mode.

What is the advantage of a Floating key? Multiple people can work at the same time, optimizing the number of seats that you have purchased.

What is the disadvantage? You can access the seat only if you are connected to the same network of your license manager machine. Note also that the license manager machine needs to be always running, so a laptop or a personal desktop machine are not usually a good choice.


How to set up your key

In order to require your key, you need to follow the instructions here: Info needed for a key creation.

Please be careful with on which machine you run the slim8_get_info command. If you are requiring a Node Locked key, than you need to run this command on the machine where you want to use EnSight. If you are requiring a Floating key, on the other hand, you need to run the command from the machine where you plan to have your license manager. 


Where should I move my key?

Now, you have your key in your hands. What are you supposed to do with it? If you have a Node Locked key, all you need to do is to move it to the directory $CEI_HOME/license8/  . If you have a Floating key, just put a copy of the key in each $CEI_HOME/license8/ directory for all the machines where you want to run EnSight from, including your license manager machine.

Now, every time you launch EnSight, the program will go into the $CEI_HOME/license8/ directory and read the key. A Node Locked key will tell EnSight: this is the machine were you are supposed to run, and this is the maximum number of instances you can have open at the same time. A Floating Locked key will tell EnSight the network name of the license manager machine. EnSight will then submit a request to the license manager, that will give it or not permission to open EnSight based on how many people are already using it.


Please note that if you are requiring a new key because yours is expired, you need to delete the copies of old key and restart the license manager (in the Floating key case), in order to avoid problems if EnSight still reads the old copy of the key.
