FLEXlm -15 Cannot connect to the license server

Troubleshooting


Problem

Attempts to open an IBM Rational product even after successfully importing License Keys results in the error "FLEXlm -15 Cannot connect to the license server".

Symptom

The full error message is as follows:

FLEXlm -15 Cannot connect to the license server


If a Server Status Enquiry is performed it shows that the license server is down.

Cause

This error is often the result of no path being defined to the license file or the incorrect path to the license path is being used.

Resolving The Problem

To resolve this error, perform the following:

  1. Open the License Tools

  2. Access the Config Services tab

  3. Using the Browse button next to the Path to the license file, navigate to the license file.

For example:

If you have permanent keys browse to:



C:\Program Files\Rational\Common\rational_server_perm.dat

If you have temporary keys browse to:

C:\Program Files\Rational\Common\rational_server_temp.dat



Also, if you have to point both permanent and temporary keys on the license server installed on Windows you may apply the following steps:
