How floating (concurrent) licenses work

If all the floating licenses are used in the same local network the installation procedure of floating licenses is the same as for the Named User licenses. Within the same network the license management is done by communication between the instances of <oXygen/> that are connected to the same local network and that run at the same time. Any new instance of <oXygen/> that is started after the number of running instances is equal with the number of purchased licenses will display a warning message and will disable the open file action.

If the floating licenses are used on machines connected to different local networks a separate license server must be started and the licenses deployed on it. Contact the <oXygen/> Support Team at to request the license server kit.

 

Procedure 2.12. Floating license server setup

  1. Contact the <oXygen/> Support Team at to request the license server kit.

  2. Install the license server in a directory on your server.

  3. You have to configure the server to look into a license directory (by default is [Server License Install Directory]/licenses) and use a certain TCP/IP port for communication (by default port 12346 is used). The license directory will contain the license files to be managed. A license file must begin with "license" and it has to have the extension "txt". It is the job of the license server to sum up the total number of licenses contained in the license files from the licenses directory.

    To change the default configuration of the license server the following parameters have to be used:

    • -licenseDir followed by the path of the directory where the license files will be placed;

    • -port followed by the port number used to communicate with <oXygen/> instances.

After the floating license server is set up the <oXygen/> application can be started and configured to request a license from it:

 

Procedure 2.13. Request a floating license from the license server

  1. Start <oXygen/>.

  2. Click Help -> Register.... The license dialog is displayed.

  3. Check the Use a license server checkbox.

  4. Fill-in the Host text field with the host name or IP address of the license server.

  5. Fill-in the Port text field with the port number used for communicating with the license server. Default is 12346.

  6. Click the Register button. If the maximum number of available licenses was not exceeded a license key is received from the floating license server and registered in <oXygen/>. If the maximum number of licenses was exceeded a warning dialog will pop up letting the user know about the problem.

    The error message contains information about the users who requested and successfully received the floating licenses.

 How to release a floating license

The floating license key registered for the current <oXygen/> instance will be released automatically when the <oXygen/> instance is closed. The license key cannot be released manually by the user.
