Setting Up Your Network License Server

This task explains how to set up a network license server, and is intended for the administrator who is setting up an environment to allow multiple client workstations to share licenses stored on one or more network license servers.

This scenario shows you how to set up a network license server on one workstation (ravel), and the scenario Setting Up Your Network License Clients two network license clients on two other workstations (mozart and chopin):

Designing the network licensing environment requires careful thought and planning. Consequently, we strongly recommend that you read the following sections in the manual Using License Use Management Runtime for your platform:
  • Chapter 2 "Planning Network Licensing": note that before starting, you must determine whether you want to use direct binding or namespace binding. For more information about what this means, read the section "Selecting a Type of Network Binding". For reliability reasons, we strongly recommend that you use direct binding.
  • the section "Setting Up Your Servers and Clients", in particular "Scenario 3: Configuring a Network License Server" in the chapter "Configuring License Use Management Runtime".
1. Log on as root onto the workstation on which the network license server is to be configured.

In our scenario, the workstation name is "ravel".

2. Go to the LUM installation location.
You configure the network license server using a configuration tool which has, in LUM 4.5.8 on AIX and Windows XP, and in LUM 4.6.X on all platforms, a graphic user interface (GUI), and on all UNIX platforms a script interface.
3. Run the command:


The Configuration Tool notebook is displayed.

4. On the Configure As page, check the Network License Server and Advanced Configuration options.
5. On the Start up page, check the option "Start services at system startup" if you want the configured server to start when you power on your workstation.
6. On the Log page, select the events you want to be logged, and specify the log file directory where you want the log to be kept.
7. If you have decided to use direct binding (strongly recommended), select the Direct Binding page, and enter in the Name field the TCP/IP host name of the server workstation ("ravel" in our scenario), then press the <<Add button to add the server to the Servers list.
8. Select Close from the system menu at the top left corner of the Configuration Tool notebook, and click the Yes button to save your changes.

On all UNIX platforms, the license server can be configured using a script. To do so, type the command:

i4cfg -script

and in response to the first question, select 3, then answer the questions when prompted.

9. Run the command:

i4cfg -start

to start the server.

10. Run the command:

i4cfg -list

to check that the server is up and running.

You are now ready to enroll your licensed products and register the licenses using the Basic License Tool.

This phase involves:

  • enrolling the products and the licenses
  • distributing the licenses to the network license server.

For detailed information and a scenario explaining how to enroll licensed products and register the licenses, refer to the sections "Performing Basic Administration", "Scenario 6: Managing a Licensed Product", in the chapter "Administering License Use Management Runtime" in the manual: Using License Use Management Runtime for your platform.

If you suspect that the license server database has been corrupted, we recommend that you run the following LUM command

i4blt -C

to check and if necessary repair the license database.
