LDRA Test tools: Setting up the client machines

This article explains how to configure an LDRA installation to obtain licenses from an existing FlexLM license server. The client (user) machines will have to be set up to access the server.

Prerequisites

Before you begin, ensure that you have:

• .ctl file supplied in the LDRA FlexLM License Delivery email
• Hostname or IP address of the license server
• FlexLM port number used by the license server

The default FlexLM port is: 27000

If your administrator has configured a different port, use that value instead.

Steps

Step 1: Install the CTL File

Copy the supplied .ctl file to the LDRA installation directory.

Alternatively, drag and drop the .ctl file onto the License Configuration dialog.

Step 2: Configure the license server connection

Use the License Configuration dialog:

1. Open the License Configuration dialog.

2. Select the FlexLM tab.

3. Select Network.

4. Enter the license server information using the following format: port@hostname

For example: 27000@myserver

You can also use the server IP address: 27000@192.168.0.24

5. Apply the changes and close the dialog.

The configuration creates or updates the LDRA_LICENSE_FILE environment variable.

Configure the environment variable manually

If required, you can configure the environment variable directly.

Windows

1. Open System Properties > Advanced > Environment Variables.

2. Create or modify: LDRA_LICENSE_FILE=27000@myserver

Linux

The setting is stored in ~/.flexlmrc

Verify the configuration

1. Launch an LDRA application, such as TBvision.

2. Open or create a project.

3. Confirm that the application starts without any licensing errors.

The License Configuration dialog should display two green check marks, indicating that licensing has been configured successfully.

Troubleshooting

License server cannot be found

Verify that:

• License server is running
• Hostname is correct.
• IP address is correct.
• Port number is correct.
• Network firewalls allow FlexLM communication.

Licensing settings are not saved

The connection information is saved only after a successful connection to the license server.

If the licensing dialog continues to appear:

• Verify the server details.
• Confirm that the server is reachable from the client machine.
• Check that the license server is running.

Application reports licensing errors

Verify that:

•  .ctl file is installed correctly.
• LDRA_LICENSE_FILE environment variable is configured correctly.
• Client can communicate with the license server.
• Valid license is available on the server.
