IBM LUM

OpenLM supports monitoring a wide and growing variety of license managers, such as FlexLM and DSLS.
This guide describes how to configure OpenLM with IBM LUM to monitor license usage, denials, and statistics.

Configuration methods

There are three ways to query the IBM LUM license server:

• Method 1: Minimal installation — Install OpenLM Server on the same machine as IBM LUM. This is the simplest setup but lacks Broker benefits.
• Method 2: Install OpenLM Server and IBM LUM client on a different machine. Server queries IBM LUM through the client.
• Method 3: Install OpenLM Broker on the IBM LUM license server. Broker queries locally and sends data to Server. This is the recommended method because it enables denial reporting and other advanced features.

Method 1: Query IBM LUM with OpenLM Server

To configure:

1. Download and install OpenLM Server.

2. In EasyAdmin, go to Administration → License Manager Servers.

3. Open the LM Tools tab.

4. From LM Type, select LUM.

5. Copy i4blt.exe to the OpenLM Server installation folder:

   • Default path: C:\Program Files\OpenLM\OpenLM Server\LM.

6. Enter the full path in the configuration and click Save.

Add a new IBM LUM server

1. In License Servers, click Add LM.
2. Enter a descriptive Description (for example, IBM LUM license server).
3. From Type, select LUM.
4. Enter the Hostname (for example, ibm_lum_server).
5. Enter the Port (default: 1515).
6. Set the correct Time Zone.
7. For Enable HAL configuration, check this if using High Availability Licensing (HAL).

Example command to obtain cluster members:

i4blt -H s -N “clusterName”

8. Configure the Use Broker toggle:

• Off (default): Server queries directly.
• On: Server relies on Broker.

9. (Optional) In Custom fields, add details such as country, scope, or description.
10. Click Save.

Methods 2 and 3: OpenLM installed on a different machine

• Method 2: Server queries IBM LUM remotely via the LUM client.
• Method 3 (recommended): Install Broker on the license server. Broker queries locally and forwards data.

Benefits of using Broker

• Robustness: Buffers data during network outages.
• Flexibility: Provides a configuration UI.
• Reports: Collects license denial information.

Method 2: Server with LUM client

To configure:

1. Make sure IIS is installed on the OpenLM Server machine.
2. Install the IBM LUM client on the OpenLM Server machine.
3. Add a reference to OpenLM Server on the IBM LUM license server.
4. After installation, copy the i4ls.ini file:

• On Windows Vista and later:

  C:\Users\<User>\AppData\Local\VirtualStore\ProgramData\IBM\LUM
  → C:\ProgramData\IBM\LUM

• On pre-Vista versions:

  C:\Documents and Settings\All Users\Application Data\IBM\LUM
  → C:\Users\All Users\IBM\LUM

ヒント

If you use the server’s IP instead of its hostname, prefix it with #. This is useful when servers are in different DNS domains.

Method 3: Use OpenLM Broker

The Broker queries license usage locally and forwards data to OpenLM Server. It requires Java JRE and can run on both Windows and UNIX/Linux servers.

OpenLM Server configuration

Same as Method 1, but ensure Use Broker is checked.

OpenLM Broker configuration

1. Download and install the latest Broker.
2. Configure Broker:

• Add Port: Enter the port set in Server (default: 1515).
• Enter OpenLM Server hostname and port (default: 5015).
• Set the Vendor name (for example, CATIADBS).

3. Configure status and data inquiry commands. Replace <fullpath> with the actual path to i4blt.exe.

Broker configuration for HAL

If HAL is enabled, include all cluster servers:

• Status command:

  i4blt -H s -N “clusterName”
  

• Data inquiry command:

  i4blt -s -lc -n “server1 server2 server3”
  i4blt -s -lco -n “server1 server2 server3”
  i4blt -lp -i -n “server1 server2 server3”

Configure Broker via web UI

1. Open Broker web UI: http://localhost:5090/.
2. Go to License Managers → Add License Manager.
3. Select LUM, enter the port (default: 1515), and click Add.

4. Configure Cluster toggle:

• Off: Single server.
• On: For HAL (see above).

5. In Commands, set the path to i4blt.exe.
6. In Vendors, set the correct name.
7. Click Save.

Verify IBM LUM in EasyAdmin

1. Open EasyAdmin.
2. Go to Start → Widgets → License Servers.
3. Confirm that IBM LUM appears in the list.
4. A green circle means active connection.

IBM LUM denial reports

Denials appear in EasyAdmin → Start → Reports → Denials.

注意

Denials are subject to true denial filtering, which introduces a short delay to confirm that a denied user was not later granted a license.

Your OpenLM system is now configured to provide IBM LUM license monitoring.
