Licensing: Setting up the client for a floating license


This article applies to customers who have an Intel® Software Development Product with a floating license. The default way to install a software product on a client machine managed by a floating license is to use the serial number while the machine is connected to the license server and checks out a license for installation. 

However, there are situations where the license manager is not available or the connection cannot be established for product activation.  It provides steps on setting up the client license to be used with the Intel® Software License Manger before installing the product. 
There are three methods to set up the client license, in order of recommended useage:

Use port@hostname

The product license checker uses environment variable INTEL_LICENSE_FILE to determine where to look for license files beyond the defaults.  You can set the value as the license server's port@hostname to connect directly to the license server without using a license file.  If you have a redundant server (triad) setup, all three servers must be specified in the environment variable.

Setting environment variables is different on Windows or Linux* or OS* X. Please see this article How to set INTEL_LICENSE_FILE Environment Variable for steps. 
The server-name and port number information can be found in the floating license file.
This method does NOT require the FLEXlm server running when installing the product.

Use the client license file 

The client license file is different from the server version in that it only contains the license server information followed by a line with USE_SERVER.  You can download this from the Intel Registration Center or modify the server license file to contain the following:

SERVER <server-name1> <hostid1> <port1>
SERVER <server-name2> <hostid2> <port2> //comment: needed for multiple servers only
SERVER <server-name3> <hostid3> <port3> //comment: needed for multiple servers only

The server-name, hostid and port number information can be found in the floating license file. The file must have a .lic extension.  You can save it to a temporary directory or to the directory where "INTEL_LICENSE_FILE" points to.

The default license folder for Intel Software Products is as below: 

  • On Windows*:     [Program Files]\Common files\Intel\Licenses\
  • On Linux*:          /opt/intel/licenses/
  • On OS* X:          /Users/Shared/Library/Application Support/Intel/Licenses

This method requires the FLEXlm server running first in order to use it for installation.

Use the server license

The server license is the exact license used by the floating license manager.  If you choose to use this method, you do not need to have the FLEXlm server running when installing the product.

After the client license file is created, you can use it to install the Intel Software Product or replace your evaluation license by copying the license file to the directory that "INTEL_LICENSE_FILE" points to.

Now the product is ready for use with the client license.
