FLEXlm license keys

Creating licenses using the Rational® License Key Center.

Most of the IBM Rational product portfolio uses a license key manager that is powered by FLEXlm software. These products include IBM Rational Suite®, IBM Rational ClearQuest®, IBM Rational Rose®, IBM Rational PurifyPlus™, IBM Rational Robot, and a series of other products.

When you download license keys from the Rational License Key Center, the downloaded file does not contain the license keys for your host that you received before the Rational License Key Center went online in May 2006. If you import this file onto your existing Windows® or UNIX® system license server, the import feature will replace your existing license key file with the keys in the downloaded file. This means you must use the Rational License Key Center to generate new keys to replace your existing keys that you received from IBM before May 2006.

For example, you had received 50 Rational Rose keys and 75 Rational Robot keys for host XYZ using the earlier AccountLink license key fulfillment system. Now, you want to add 100 Rational ClearQuest keys for the same host, XYZ. You access the Rational License Key Center, and generate 100 Rational ClearQuest keys for host XYZ. The file that is downloaded from the Rational License Key Center for host XYZ will not contain the Rational Rose and Rational Robot license keys because those keys came from AccountLink. When you import the downloaded file from the Rational License Key Center the existing license key file containing the 50 Rational Rose keys and 75 Rational Robot keys is overwritten with the downloaded license key file that contains only the Rational ClearQuest license keys. As a result, the license server manages the Rational ClearQuest keys only.

To prevent this situation, you must go to the Rational License Key Center and generate Rational Rose and Rational Robot keys for host XYZ. The license key file will then include keys for all three products for host XYZ:

License key file downloaded from the Rational License Key Center for host XYZ:
  • 100 Rational ClearQuest keys
  • 50 Rational Rose keys
  • 75 Rational Robot keys

Downloading and importing this file from the Rational License Key Center will overwrite the existing license file with the new license file that now contains keys for the three products: Rational Robot, Rational Rose, and Rational ClearQuest.

To add another license key for Rational PurifyPlus to this host, generate the Rational PurifyPlus keys for host XYZ, download and import the file that now contains keys for the four products.
