The OpenLM Proactive Application Manager – AN4058

General

OpenLM has been addressed by numerous customers who expressed their concern regarding loss of control over software license checkouts. These customers complained they could not deal with excessive license consumption, resulting in unplanned expenditure or breach of licensing compliance.

OpenLM now presents the capability of directly intervening in the process of license drawing. We call this the “OpenLM Proactive Application Manager”.

Benefit of the OpenLM Proactive Application Manager

The OpenLM Proactive Manager serves as a shell for vendors’ license managers. It provides intricate license management capabilities that are not provided by the vendors’ license manager.

It is designed with the users’ best interest in mind, and with the intention of returning control back to the software users.

The OpenLM Proactive License Manager interfaces the the end-users workstations through the OpenLM Agents, and may be configured to intercept the launching of applications according to predefined configuration.

Components

The image below depicts a simplified block diagram of the OpenLM Proactive application manager solution:

1

The OpenLM Proactive application manager solution is comprised of the following four components:

The OpenLM Agent is a lightweight software component that should be installed on end users’ workstations. The OpenLM Agent:

  1. Monitors processes running on the workstation
  2. Catches events of software launching
  3. Provides the means to intervene in the execution of specific processes on the workstation

The OpenLM Proactive Manager is a Java application that acts as a hub to all OpenLM Agents. It needs to be installed on the same machine as the license server (e.g. FlexLM), adjacent the OpenLM Broker. The OpenLM Proactive Manager:

  1. Is configured by the OpenLM Server.
  2. Obtains information from the Agents regarding active processes and software launching.
  3. Ascertains whether to grant permission, and enables the Agents to launch the software according to the said configuration.

The OpenLM Broker Needs to be installed on the same machine as the OpenLM Proactive Manager. This may, or may not be installed on the same machine as the License Manager (e.g. FlexLM license server) . The OpenLM Broker facilitates the connection to the OpenLM Server.

The OpenLM Server is the main OpenLM component. It:

  1. Provides an administrative interface to configure the OpenLM Proactive application manager,
  2. Maintains license usage information in a database,
  3. Provides a platform for reporting license usage.

Installation

All components are available for download in the Downloads section on the OpenLM site.

After installing the software, make sure the “OpenLM License Manager” service appears as ‘Started’ in the Windows services list.

OpenLM Broker

The OpenLM Broker needs to be installed on the same machine as the OpenLM Proactive application manager, on a stable Windows machine, with decent network connection. Please refer to these documents for more information:

OpenLM Broker Installation Guide: Comprehensive – AN4004b

OpenLM Broker installation Guide: Quick Reference – AN4004a

Follow the OpenLM Broker’s installation wizard’s instructions to complete the installation, and make sure the  “OpenLM Broker” service appears as ‘Started’ in the Windows’ services list

OpenLM Agent

The OpenLM Agent can either be installed manually per workstation, or silently distributed by a script: OpenLM Agent Silent Installation.

During installation, the user should choose to add the Proactive application manager extension.

After installing the software on the workstation:

  1. The OpenLM agent icon will appear on the taskbar:    3
  2. Make sure the “OpenLM Software Locker”  service appears as ‘Started’ in the Windows’ services list.

OpenLM Server configuration

In the OpenLM Server configuration tool, set up the OpenLM Proactive application manager to be monitored as if it were any other license server:

  • Fill in the OpenLM Proactive application manager’s Server name and Port (e.g. localhost and 27080)
  • the OpenLM Proactive application manager’s timezone
  • A descriptive name (e.g. openlm_license_manager)
  • Type: OpenLM Generic
  • Click ‘Apply’ and the ensuing “Restart Now”

4

OpenLM Broker Configuration

Set up the OpenLM Broker to query the OpenLM Proactive application manager as if it were any other type of license manager

  1. Fill in the OpenLM Server name and port number (e.g. Localhost, 7016)
  2. Fill in the OpenLM Proactive application manager name and port number (e.g. Localhost, 27080)
  3. The License manager type should be set to “OpenLM Generic”
  4. The ‘Status’ and “Data Inquiry” should refer to the lmstat.bat batch file, e.g.:“C:\Program Files (x86)\OpenLM\OpenLM License Manager\lmstat.bat”
  5. Click the ‘Apply’ and “Restart Broker” buttons

5

In order to accumulate license denial information, configure the Broker to read the OpenLM Proactive application manager log file. This log file has a similar format to that of FlexLM debug log files, and should be configured as such. The  OpenLM Proactive application manager log file is normally located at:

C:\ProgramData\OpenLM\OpenLM License Manager\logs\lm-log.log

6

OpenLM Agent configuration

In order to enable the OpenLM Agent to intervene in the process of software launching, it must be configured as follows in the Agent Configuration interface:

On the “General” tab:

1. Fill in the OpenLM Server’s name or IP (e.g. my_openlm_server) and Port number (default 7012)

2. Click the “Check connectivity to OpenLM Server” to verify this configuration.

10

On the “OpenLM Proactive Management” tab:

1. Check the ‘Enable’ box

2. Fill in the OpenLM Proactive application manager’s details: Server name and Port (e.g. my_openlm_license_manager, 27080).

3. Check the connectivity to the OpenLM Proactive application manager by clicking the adjacent button

11

4. Click the ‘Configure’ button to add or edit products that are to be managed by the OpenLM Proactive application manager:

  • Type in their descriptive name (e.g. ‘PlusPlus_name’)
  • Type in the full path of the directory that contains their executable file (e.g. C:\Program Files (x86)\Notepad++ which contains the file notepad++.exe)
  • Assign an arbitrary code name (e.g. ‘PlusPlus_code’)
  • Check the ‘Enabled’ box to select whether to intercept the launch of the product of interest (e.g. Notepad++ in this example)
  • Click the ‘OK’ button to apply the changes.

12

Configure the EasyAdmin web interface

In the EasyAdmin Web application click  the start → Administration → “License Manager” icon.

  1. Observe the Products that have been enabled on the OpenLM Agent “OpenLM Proactive Management” (e.g. Notepad++, above). 
  2. Set a limit to the number of licenses, e.g. 4. Notes:
    • If all workstations have the OpenLM Agent installed on them with the demonstrated configuration, and are connected to the same OpenLM Server and OpenLM Proactive application manager , the said configuration will limit the number of launched applications (e.g. Notepad++) to 4.
    • In order to set an unlimited number of licenses, so that OpenLM would not intercept the launch of the , set the limit to -1.
  3. Set the ‘bucket’ policy resolution. In the case of Bentley, the resolution should be set to 1 hour.
  4. Set the “Release Delay Minutes” parameter . This number represents the minimal session length in minutes according to the specific license server. In the case of Bentley, this parameter should be set to 10 minutes, as Bentley considers the minimal session length to be 10 minutes. Note that this  also means that Bentley considers every session that is longer than 50 minutes as consuming at least two ‘buckets’.

EasyAdmin indications

  • Launch a Notepad++ application on the end-user’s workstation.
  • Observe the number of used licenses in the “License Servers” and “Currently Consumed Licenses” windows
  • The OpenLM Proactive application manager denial reports are available on the lm_log.log file, which is read by the OpenLM Broker (See above). Observe the EasyAdmin ‘Start’ → ‘Reports’ → ‘Denials’ window to view license denials.
