  4. It provides license denial information for specific license manager types.
  5. It provides 1-second resolution license usage information for specific license manager types.
  6. The OpenLM Broker is required for attributing license usage to specific license pools in a multiple pool environment.

  8. It facilitates uploading of FlexLM license files from the  local machine running the EasyAdmin web application to the remote license server machine.

OpenLM Broker – Installation Guide

The OpenLM System components are available for download on the OpenLM site. After filling in a username and email, the user will be directed to the download section. Select the OpenLM Version 3.0 on premise section.


In order to install the OpenLM Broker module on a Windows platform license server:

  1. Please go over the installation prerequisites for the OpenLM Broker.
  2. Download the OpenLM Broker for windows from the OpenLM version 3.0 section (see above), and follow the installation instructions. OpenLM will install the Java Run-time Environment (JRE) as part of the Broker installation.

  3. Open the OpenLM Broker configuration tool (Windows ‘Start’ → “All Programs” → OpenLM → Broker → “OpenLM Broker configuration tool ”). Note that the Broker automatically detects the settings of FlexLM license managers installed on the machine. The existence and location of FlexLM Options files is not automatically configured; Setting their names and paths remains to be done manually.

Unix / Linux

For Unix / Linux installation – please refer to the Comprehensive Broker guide.

1. Mark the “OpenLM Servers” directory icon.

2. Click the green “Add” icon

3. Select “OpenLM Server” from the selection list.

Adding a license server

The Broker connects to license server ports, and conveys license usage information to the OpenLM license server. On windows’ installations, the Broker configuration tool automatically detects FlexLM License Managers on the host machine upon first startup. It displays a list of these license managers under the “License Servers” folder on the left pane. In order to add a license server manually, please do the following:

  1. Select “License Servers” on the left side of the screen.
  2. Click the “Add” button. A drop-down list appears.
  3. Type in and enter the hostname or IP of the new License Server. Make sure the hostname or IP configured on the OpenLM Server Configuration tool and on the Broker configuration tool are the same (see images below).

License manager port:

1. Click on the “Port” node under the new License Server key symbol. The “License Manager Port” form appears.

2. Fill in the License manager port parameters:

  • Port Number: This Number is the same as the one configured in the “OpenLM Server Configuration Window”, under the “License Servers” tab.
  • License Manager Type: Type of License server (e.g.: FLEXlm).

3. Type in the vendor name, under the newly created ‘Port’ node (e.g. for Autodesk, the vendor name is adskflex)
